General Hydroponics was founded in the mid-70s near San Francisco, California, by a group of scientists, researchers and technicians. Today, GH is recognised by the international scientific community for its reliability, the quality of its products and its sense of innovation.

Within a few years, our reputation crossed international borders, extending to Canada, Australia and on to Europe, where GH Europe was established in 1995 in the South-West of France.

Since the beginning our objectives have remained the same: to stay at the cutting-edge of technology, to offer the best quality of service and to bring solutions for some of the environmental problems that our planet faces today.

Our technology is called “Aero-hydroponics”: plants grow without substrate, in a perfectly balanced flow of nutritive solution, saturated with oxygen. (A more detailed description follows.) Thanks to its flexibility, this alternative growing method holds an enormous potential of opportunities. It can be adapted to most situations, allowing one to grow anywhere, from the city to the most remote countryside.

One of the first concepts we developed in California was the hydroponics “MicroFarm.“ A Family Farm allows a family or individual, wherever they are based, to produce part of the vegetables they consume, eliminating the expensive middlemen, and eventually providing surplus to sell within the local farmers’ markets, co-ops, restaurants, etc.

In our greenhouse in the south of France, we study the potential of several high value cash crops that will give the grower an alternative to traditional crops, and will allow him to step out of the vicious circle of subsidies. We especially study the field of medicinal plants, where there exists a constant demand of quality stock, and where it is urgent today to stop the gathering of many endangered species. Our research is aimed on selecting the right species, optimising their harvest and increasing their content in active principles.

Aware of the insufficiencies in the food and water supply on the planet, we participate in food development projects in the third world. Indeed, by adapting our technology to the existing resources, we teach populations a way to provide for their immediate basic needs and to create, whenever possible, an unexpected but well needed source of income.

As environmentalists, when possible we utilise recycled and regenerated materials. To respond to the problem of electrical consumption, we are currently testing in California the first systems powered by solar energy.

Today, after several years of intensive research, we are proud to offer you “bioponics” - or organic hydroponics - a new concept in plant cultivation (patent N° 05.11569), which combines the advantages of hydroponics with those of organic farming, while responding to the principles of sustainable development.

Our line of products is vast, often unique and always in evolution. It is developed by our team of researchers, thoroughly studied, then tested in our greenhouses in California and in France. Today our products are used by growers worldwide. They are sought after by the most important laboratories in the world and NASA uses Flora Series and the AeroFlo in their studies on cultivation in their space stations.

GENERAL HYDROPONICS


In 1995 GH Europe was founded in South-Western France to better serve the new European market, with a range of services also covering Africa, Asia and the Middle East. Eighteen years later, GHE gained a dominant position in Europe and opened a great number of markets in countries as varied as Japan, Russia, South Africa, India and Kuwait.

With North America, Australia, Europe and the many countries that join us every day, GH is today a major reference on the world hydroponic market.

This is, of course, especially due to the quality of our products, but also to the reliability of our technology and our unfailing commitment to the principles which always inspired us: Sustainability, quality, simplicity and innovation.

Today, 30 years after being founded by Lawrence Brooke, GH has built factories in California (the west coast of the United States), in Virginia (the east coast) and in Europe (France). This enables us to be close to our markets, in closer contact with our clients, and allows us to react e"ciently and rapidly.

We are also able to adapt to the rules and regulations of the di#erent countries that we serve, and to o#er you authorised and reliable products. Finally, thanks to our local manufacturing, we participate in the growth of our

communities, and we eliminate a large percentage of unnecessary and polluting transportation.

Over time, and because of the di#erences between the markets and regulations on the two continents, our product ranges in the United States and in Europe have been slightly diversi$ed, except for Flora Series, the original fertiliser on which our excellent reputation is built and which still remains a reference of quality at the international level. To maintain the similarity of our two product lines, while respecting the regulations of di#erent countries, we have sometimes had to o#er di#erent products with the same name. But they all serve the same objective in di#ering environments, and will give you the same total satisfaction.

In Europe and in the United States, we also developed the $rst worldwide range of organic products adapted to hydroponics (which we call “bioponic“ products). Based on BioSevia and BioThrive, this range is o#ered under the name of “General Organics.”

In Europe, all our products are tested in our greenhouse. This is also where we grow our collection, a large variety of plants from all over the world. For additional information you can see our greenhouse on www.ghe-blog.com or, if you are visiting the Gers and would like to see for yourselves, don’t hesitate to visit us in Fleurance (France).

GENERAL HYDROPONICSEurope


What is hydroponics?Hydroponics is the art of growing plants in water. The word comes from the Greek “hydro” (water) and “ponos” (work). The concept was rediscovered in 1930, at the University of Berkeley in California by Dr. Gericke, but in reality this growing method has existed since the earliest of times.We have all heard of the hanging gardens of Babylon, and of those people living at altitude around mountain lakes like Titicaca in Peru and Inle in Myanmar, who cultivated their gardens on water surfaces, over straw mats, water hyacinth beds or any other local substrata. In hydroponics, as in these mountain lakes, plants live over water with their roots hanging in the dynamic flow of a nutrient solution.Although plants such as rice and water lilies or carnivorous plants can adapt well in scarcely oxygenated, or even stagnant environments, most have difficulty in adapting to oxygen deficiencies. Indeed, if a plant lacks oxygen in its root zone, it asphyxiates even though it is adequately watered: actually a recurrent cause of death for houseplants is due to over watering. This is often what happens in “hydroculture” (not to be confused with “hydroponics”), a growing method with wicker buckets standing in a “dormant” nutritive solution.Thus, plants can grow in water, but not under all conditions. Water has to be “alive.” One must be aware that, whatever the environment they are growing in, be it soil, air or water, plants absorb their food in the form of ions dissolved in oxygen. In water, when food and oxygen are absorbed, they must be replaced. This is the function of hydroponics: a soil-less cultivating method which stimulates plant growth while controlling the quantities of water, mineral salts and most importantly, dissolved oxygen.The basic concept is quite simple. When roots are suspended in moving water, they absorb food and oxygen rapidly. If the oxygen content is insufficient, plant growth will be slow. But if the solution is saturated with oxygen, plant growth will accelerate. The grower’s task is to balance the combination of water, nutrients and oxygen, with the plant’s needs, in order to maximise yield and quality.To obtain the best results, a few important parameters need to be taken into account: temperature, humidity and CO2 levels, light intensity, ventilation and the plant’s genetic make-up. Essentially this is what any conscientious gardener would do.

And what are its advantages?Hydroponics can be used by a wide range of people: plant lovers in general, private or professional plant collectors, small and large greenhouse growers, horticultural societies, research centres, schools and many more.The following list is a summary of its applications and advantages:

! Optimal utilisation of the plant’s genetic potential.! Better control of the plant’s nutrition.! A visible improvement in quantity and yields.! A significant shortening of the growth / production interval for a large variety of species.! A more efficient use of space.! An excellent propagation success rate.! Huge savings on fertilisers, and most importantly, on water in a situation of ever increasing global scarcity.

Often when discussing hydroponics we are greeted, not only by a lack of knowledge, but also with incredulity, scepticism and occasionally downright disapproval, especially when we explain that this method of cultivation consists of growing plants directly in water and plastic, rather than in soil.

And yet our technology represents one of the most sensational developments in recent years. It is increasing rapidly worldwide, spreading into all kinds of projects, from vegetal walls to urban gardens and family farms of all types.

Hydroponics:A Technology for Today

GHE


! A total absence of herbicides. To replace pesticides and fungicides, hydroponic growers will often use IPM (Integrated Pest Management).

! The strength and vigour of plants started in hydroponics then transplanted in soil is such that it opens up enormous commercial perspectives, especially for potted plants.

! In the field of education, at all stages, hydroponics fills children and adults with wonder. Several countries have already introduced it into their school or university programmes.

! Last but not least, hydroponics was, and still is, used for research purposes. For the last 50 years this method has been applied in the most important research centres because of its reliability, its precision and the broad spectrum of its applications. Thanks to hydroponics enormous advancements have been made in the understanding of plants and especially their nutritional requirements.

Like all things, hydroponics can have good or bad results depending on the people who apply it and their objectives. ! It can be used for mass production and to produce tomatoes with little taste or roses with no perfume. But it can grow

products with the best nutritive qualities, bursting with flavour and aroma. ! It can be a pollutant when used with rockwool or in run-to-waste conditions. But it can be applied ecologically in respect

to the environment, sustain a large portion of the planet’s population with quality food and allow third world countries to feed their own people, even when the soil is poor and water scarce.

Another recurring question: Are hydroponic crops organic? The answer is no, they are not. The mere fact that this is a soil-less operation already prohibits an “organic” designation. As for the fertilisers, there was no complete organic nutrient for hydroponics until now. In 2004, William Texier, head researcher in our European laboratories, created BioSevia, the first and only complete organic nutrient for hydroponics that complies with the European regulation on organic agriculture. Furthermore, our mineral fertilisers are so precisely crafted, that they leave no toxicity or heavy metals whatsoever in plants, when used according to the instructions. Today several variations of our technology are on the market: NFT, Drip Systems, Ebb & Flow, Aero-hydroponics. They are applied in industrialised countries like Australia and Canada, and are spreading to many Southeast Asian countries, where an increasing acreage of hydroponic greenhouses are used to grow vegetables, fruits, potted plants, cut flowers, etc.In some third world countries too, teams of volunteers are teaching people to build their own hydroponic systems from indus-trial scrap, and to produce fertilisers with domestic waste.Hydroponics has other applications, particularly in the field of outdoor and indoor gardening. In the US, for more than 30 years, manufacturers have been developing small-sized units for hobby gardeners, using the same technology as the green-house industry. Those systems are designed for the wider public and can be installed on balconies or patios and in sitting rooms and kitchens. They vary from one-plant mini-modules to small kitchen gardens.It is true that these techniques are not relevant for everyone. A common error is to think that if plants have sufficient water supplies then they can be left unattended for longer. In fact, their accelerated metabolism requires greater attention. This methodology is not to save time on maintenance, rather it is conceived to maximise results. In this sense, hydroponics is intended for plant lovers and collectors, from beginners to professionals, rather than for the occasional gardener. Of course, the concept of hydroponics may appear inconceivable to some or just another fad. Others will be curious, amused or interested. To you all, whatever your reaction, don’t hesitate to contact us to give us your opinion or to request more information.

FLORAduO® Floraduo Grow, Floraduo Bloomconcentrated liquid nutrient

THE ULTIMATE IN 2-PART PLANT FOODSFloraDuo is a “classic“ mineral nutrient with a di# erence (and an essential one) where each of the elements a plant needs is derived from a large variety of di# erent sources.To create an excellent nutrient you need, of course, a precise formula. But this is not all you need! It’s also very important that each element is derived from di# erent sources and di# erent salts. This is how all the elements are made available at all times, in an easily absorbable form. And we don’t stop at that! We also add “bio-activators” into each bottle. These are not direct nutrients for plants, but instead they improve the plants’ general health, help them to better absorb their food and increase their resistance to pathogens and insect infestations.FloraDuo is a complete nutrient, especially designed for fast growing plants, with a marked di# erence between growth and ! owering needs. It comes in two parts: FloraDuo Grow and FloraDuo Bloom. To guarantee the best results, FloraDuo “Grow” is available in both hard water and soft water versions. Use FloraDuo Grow “soft water” also for demineralised and reverse osmosis water.Note that the internodal distance is shorter with FloraDuo. That is accomplished through our use of puri" ed nutrients, NOT by using PGRs (Plant Growth Regulators). Shake well before using.

RIPEn®late flowering nutrient

Ripen is a complete nutrient and can also be used as a stimulant: It increases flowering and production of active principles. It eliminates nutrient excess.

Ripen is a mix of refined mineral salts and buffers, formulated by our laboratories with the greatest precision. Indeed, at this stage, accuracy is of the utmost importance. The plant, at the end of its life, is generally more fragile and the assimilation process is greatly reduced when compared with the vegetative phase.

Ripen acts at different levels: It gives the plant a strong signal that it is coming to the end of its life. The

plant reacts by speeding the ripening process, in a last effort to spread its genes.

It forces the plant to strengthen its defences and thus increase its active principles.

It delivers all the mineral salts the plants need in a form easy to assimilate. In case of a previous accumulation of nitrate or microelements, it helps

metabolise these residues, which will improve the taste of the crop.

Ripen

Ripen has many properties:

Outdoors, it enables you to quickly harvest a crop before it is spoiled by cold and damp weather. Indoors, it helps you harmonise the end of the grow cycle by speeding up the ripening of the slowest plants. In case of a severe infestation of fungi or insects, it allows you to accelerate the natural cycle and get

something out of a crop that would otherwise be completely lost. It allows metabolisation of mineral salts excess. It increases the active principles in medicinal plants.

Ripen is a “forcing solution.“It is designed to accelerate plant ripening,

improve content in active principles, and eliminate mineral salt residues.To achieve best results :

Hydro : EC = 2.4 - 2.8. - Soil : EC = 2.2 - 2.6.RIPEN IS A POWERFUL NUTRIENT. ADAPT THOSE ECS TO THE VARIETY OF YOUR PLANT AND ITS GROWING CONDITIONS

BioSevia®BioSevia Grow, BioSevia Bloomconcentrated organic plant food 100 % soluble

BioSevia is the spearhead of bioponics. It is the first nutrient for hydroponics to be authorized for organic cultivation.BioSevia is the first authorized organic nutrient to be complete and perfectly soluble. For four years our researchers studied and tested exhaustively to obtain a nutrient containing everything a plant needs to perfectly grow, and which would at the same time, respond to all the requirements of a European organic registration.

BioSevia has several essential qualities: It is an exhaustive plant food that conforms to the European regulation on organic

agriculture N° 837/2007. Its specific composition and its excellent solubility make it easy for plants to

assimilate. It contains fulvic and humic acids which improve soil conditions and enhance the

plant’s absorption capacity. It contains amino-acids. It is efficiently applied in fertigation and drip irrigation. It brings a sweet, pleasant taste to your crop. It works in soil and also in hydroponics!

Feeding charts for bioponicsare available with each BioSevia product (see page 49).

BIOSEVIA® IS A "BIOPOnIc" nuTRIEnTBioSevia gives perfect results in soil but uniquely works beautifully in hydroponics too, be it with bare roots or on substrates. No other nutrient is adapted to this type of growing.

Generally, organic nutrients are formulated in order to slowly decompose in soil, so when in water, some of their elements will rot and release quite unpleasant smells. They would also clog filters and drippers.

To be bioponic, a nutrient must be liquid and perfectly soluble. It must be rapidly degradable and readily available to the plant. BioSevia accomplishes all these conditions.BioSevia Grow and Bloom are very concentrated: 2 ml / L are enough for a complete and balanced plant nutrition.

BIOPONICS (or ORGANIC HYDROPONICS)

Patent N° 05.11569 - 15/11/05

BM (Trichoderma harzianum) micro-organisms:bioponic mixBioSevia works perfectly in soil. We recommend using a small amount of BM (1g / 10 L) every 6 to 8 weeks to facilitate the decomposition of organic matter and to enhance growth performance.

In hydroponics, it is essential to use BM to recreate the decomposition process in the nutritive solution that would happen naturally in soil.

bioponics

BioSevia and Bioponics

BM is only used to breakdown organic matter.

In hydroponics, do not use Mineral Magic with micro-organisms. See page 25.

Bioponics or ”organic hydroponics”Bioponics creates everything that a plant needs in the nutritive solution for perfect growth.For many years researchers of several countries have been looking for an efficient way to achieve real organic hydroponics. It was William Texier who in 2004 discovered and adapted the concept of bioponic growing, the new method for an organic hydroponic cultivation. Patent N° 05.11569 - 15/11/05.Bioponics goes much further than just a change of nutrients. The concept is “liquid earth.” BioSevia, the appropriate nutrient, was the missing link. By combining it with BM, bioponics creates everything a plant needs in the nutritive solution.The water is present, of course, and oxygen too, especially if the growing system is well designed. You need to add:

BioSevia: the nutrient that brings the humus fraction of soil, and which contains a wide range of large organic molecules to reproduce the complexity of soil in the nutritive solution. It is specially designed for this utilisation (to recreate the natural fertility conditions of soil, but without soil).

BM (or ”Trichoderma harzianum”): the micro-organisms which bring microbial life and participate in the carbon cycle.

How to manage the micro-organisms?In water, the life conditions of micro-organisms are not very comfortable, as they lack the buffering capacity of soil that protects them against sudden fluctuations in temperature or pH. They also need to be ”fixed into a substrate,” and cannot survive and propagate in water alone. They need a highly oxygenated and wet habitat. If they dry they’ll die!There are two possibilities:

On humid substrate like coco fibre, rockwool or perlite, simply sprinkle BM directly on the substrate. On bare roots or in draining substrate like clay pebbles or lava rock, use GHE BioFiltre, or build your own. Biofiltres provide

your micro-organisms with the correct environment to live in and develop (see p. 17).Use 10g/100 L of nutritive solution. Add every six to eight weeks.Wherever they are, in a BioFiltre or directly in the substrate, the micro-organisms will happily thrive as long as their environment is oxygenated and humid. To guarantee good development, it is imperative to avoid any sudden changes, especially in temperature and pH levels. The happier and more abundant your BMs are, the better fed your plants will be!

BM conforms to the European regulation 2008/113/CE on organic agriculture.

It is registered in Germany under: BBA Nr LS 004987-65-00.

BM is available in


GHE

Important note for organic farmers:Agencies certifying organic produce do not recognise hydroponics as an organic means of cultivation, even when you use BioSevia. Soil is the basic criteria for an organic certification, and as we all know, hydroponics does not use soil as a substrate. This is why growing hydroponically will not be considered as organic, and hydroponic crops will not be given an organic certification.

How to manage bioponics

Managing bioponics needs much more attention than a traditional hydroponic growing method. Not in terms of time spent, but in terms of “visual attention and examination”. Bioponics is managed by eye as much as with pH and EC parameters, although these do still remain important references. Here are a few basic notions to guarantee your success when growing bioponically.Also use the feeding charts given with BioSevia.

pH levelBioSevia has an almost neutral pH. It will not affect your water. During cultivation, the pH is more difficult to stabilise than in mineral hydroponics because (the somewhat quite arbitrary!) organic regulations prohibit the use of some extremely efficient buffers. This means the pH will tend to rise.But the pH doesn’t have the same importance in bioponics. It can rise up to 7.5 with no problem. Over 7.5 it has to be driven slowly down to 6.0, but progressively, over a period of five to six days. To do so, use GHE’s liquid pH Down, as it contains organic buffers and adapts well to BioSevia. (Note: GHE’s pH Down is not an organic product.)Add your regulator slowly, little by little, and dilute it well each time. Pour it into the reservoir, far away from the pump (or switch the pump off ). This will help to avoid plant stress due to a rapid a change in pH levels.

Absolutely avoid: chlorhydric and acetic acids (vinegar, etc).

A significant drop in pH is an alarm bell that indicates the death of a large quantity of micro-organisms. In this case it is important to find the cause, treat it, and replenish micro-organisms.

ConductivityThis is the most complex part of the bioponic process because organic molecules don’t carry electric charges, and therefore, are not read by your EC meter. When you dilute BioSevia in water, only a small fraction is immediately dissolved and transformed into ions, resulting in very little conductivity.

On day one, with a dose of 15 ml / 10 L added to normal tap water, you will obtain a reading around 0.65 (0.6 to 0.7). This low conductivity is generally enough.

After this period, only add nutrient when your EC goes under 0.8. At that stage add 20 ml / 10L. Keep your conductivity under 1.0 and above 0.8.

Use this dosage without changing the nutritive solution, if possible, to maintain all the benefits of the environment you have already created.

While nutritive elements are liberated, others will be absorbed by the plant, and conductivity will tend to remain in balance around the same values. When the stock of organic matter becomes insufficient, EC will drop. It is time to add more nutrient.This looks simple, but to obtain the best results, it is important to anticipate this drop in EC, and ensure the constant availability of organic matter. Do not add too much nutrient at once as the breakdown of molecules happens according to room temperature. In fact, micro-organisms act at radically different velocities depending on temperature fluctuation in the nutritive solution. If there is too much organic matter in the solution, a rise in temperature could increase conductivity to a level that will harm your plant.

It is not always easy to find the correct balance. This is where the grower’s eye will make the difference!

ADVANTAGES OF BIOPONICS

Bioponics is founded on one of the very basic principles of sustainable, organic agriculture. This consists of giving small quantities of nitrate to the plant in order to increase flowering and fruiting rather than producing abundant, but sometimes useless, vegetative growth.

Indeed, this is one very interesting aspect of bioponics. You create very little vegetative mass compared to yield. For the same yield, 1 kg of tomatoes grown in bioponics would produce a much lower volume of leaves and stems than 1 kg of tomatoes grown using classic hydroponic (and even soil) methods! This makes bioponics a very economical way to grow, as water and nutrient consumption is very much reduced in comparison to any other form of cultivation.

Bioponics combines the advantages of hydroponics with organics. It helps to save water and nutrients and grow good quality, organic crops in smaller areas. However, it does not allow you to obtain an organic certification for the products you grow.

Tomato roots grown in an AeroFlo with BioSevia and BM.

FiltrationFiltration is very important, especially in hot weather conditions, and when working with bare roots that hang directly in the nutritive solution. It is indeed necessary to filter the largest particles, as they could asphyxiate the roots, particularly in hot weather. It is always better to have only easily assimilated ions in the root zone.With BioSevia, a simple foam filter on the pump’s input is enough. It will not clog the filter. But still, thorough and regular filter maintenance is required. Rinse once a week for best results. Make sure you stop your system while cleaning.

The plant’s environmentThe environment must be adapted to the plant, independently from the growing method you use. Temperature, humidity, cultivation cycle, prevention and pest control, must, of course, be adjusted to your plant’s needs.

General Organics provides gardeners with a complete line of superior plant foods and supplements. Each product in the “GO” line enables you to enrich your garden, your life and the planet. General Organics products bring together the time-tested materials of traditional gardening with the ecological and efficient methods of the future. General Organics represents our deep commitment to sustainability, quality, simplicity, and innovation.

Launched into the North American market by GH US in 2008, GO has received fantastic success. California is home to some of the world’s best growers, so having passed the ‘Californian Test’ we know that we can really trust the products. We are continually receiving positive comments from satisfied customers.

GO includes our current organic fertilisers, as well as new additions, some of which have been developed in Cali-fornia and others in France. All the GO line has the same objective: to improve plants’ health and their resistance to sickness, and to increase flowering and fruiting not only in quantities, but most importantly, in quality. Of course, we don’t expect you to use all these products at the same time! Even though they all serve the same objective, they don’t all work in the same way. They work in synergy at different levels of the plant’s physiology.

With the GO line, we offer you a new concept where you don’t need to follow pre-established feeding programmes. Instead, you can choose your preferred supplements and mix them according to your own needs. You will notice that there are two root activators (BioRoot Plus and Bio Roots) and two bloom activators (BioBud and Bio Bloom) in our supplement line. Our traditional boosters Bio Roots and Bio Bloom are highly concentrated and are usually sold in 30 ml and 60 ml bottles whereas BioRoot Plus and BioBud are sold in larger bottles. Of course, you should not use both of them. Some growers choose the super-concentrated forms and others prefer to work with ml rather than with drops. The products are not the same, but they produce the same great results!

With General Organics, the feeding charts we provide are guidelines with multiple choices and we advise you on the combinations that we think are the best. But the GO product line is your playground. An open space for your creativity, innovation and your best personal formulas!

dIAMOnd nEcTAR® natural bio-stimulatorDiamond Nectar is an exclusive fulvic acid extract from a combination of unique Leonardite sources providing the highest availability and diversity of these bio-active plant compounds. It is a stimulator for all stages of plant growth.

Millions of years ago, prehistoric plants and animals were consumed in the ecological cycle of life. Buried thousands of feet deep and converted to carbon, some of these deposits produced “Diamond.” Others were pushed to the surface during the ice ages and became what is known as “Leonardite.”*

* The General Hydroponics research team has analysed over 300 different Leonardite sources around the world to create a proprietary, pH balanced, fulvic acid with maximum agronomic benefits.

Beneath some ancient lands in New Mexico, an extraordinary Leonardite deposit was formed. It contains the riches of natural organic matter composted for millennia and freely available to growing plants. This deposit is carefully mined and natural compounds called “Humates” are extracted. Soluble Humates (the humic and fulvic acids family) contain a myriad of natural plant growth promoting compounds plus nutrient enhancing ingredients. Diamond Nectar is not a fertiliser. It is an additive to be used in combination with comprehensive nutrients like Flora Series, FloraDuo, FloraNova and BioSevia. Combined with a conventional nutrition programme, it leads to earlier harvests, healthier disease resistant plants and enhanced qualities of flavour, fragrance and essential oils, plus significantly higher yields. Apply Diamond Nectar to all cultivated plants, including ornamentals, culinary and aromatics, fruit and vegetables, trees etc. It is adapted to hydroponics and soil. Pour directly into the reservoir or use as a foliar spray.

Thanks to its leveling and chelating action, as well as its important ionic exchange capacity, Diamond Nectar:

increases the size of the root system, and therefore improves absorption of the nutritive elements.

transports nutrients to all plant parts: roots, stems, foliage, flowers and fruit.

affords growers the benefits of natural organic matter in a liquid form.

In hydroponics and soilless cultivation, Diamond Nectar helps to create an environment closer to soil conditions.

Mineral Magic

MInERAL MAGIc®organic natural additiveSilicate is an essential element for higher plants, especially when growing with water as a substrate. Mineral Magic contains ancient sea-bed deposits of biologically transformed organic matter, plus naturally formed silicic acid clay.

Mineral Magic is an organic product. Use as a natural additive to the nutritive solution.

!IMPORTANT NOTICE :MINERAL MAGIC AND MICRO-ORGANISMS:

In hydroponics, avoid using Mineral Magic with the micro-organisms (BM). It is counterproductive since in water, silicate dissolves into silicic acid, which slows the develop-ment of beneficial colonies.

Conversely in soil, when mixed in powder form, the large range of elements included in Mineral Magic stimulates the growth of beneficial micro-organisms, and helps create a natural environment for extremely healthy plants.

Mineral Magic provides a naturally soluble form of silicon which enters plant cells and builds a hardened shield against disease and insect attack.

Mineral Magic’s natural colloids improve cation exchange capacity to nutrient solutions. This enhances nutrient availability.

Stabilises nutrient solution pH and conductivity which reduces stress for rapidly growing plants.

Protects against toxicity of metals.

Last but not least, Mineral Magic also contains more than 60 minerals, which add more nutritive elements for plants to thrive on.

BIO ESSEnTIALS® comprehensive mix of micro and sub-micro elements

Bio Essentials is a unique product: it is a comprehensive concentration of micro-nutrients in a chelated form, plus essential sub-micro particles and an organic buffer. It is used as a complement to the nutritive solution in soil and water culture, as well as in foliar spray.

Micro and sub-micro nutrients are essential trace elements that a plant needs, in conjunction with primary and secondary elements, for a comprehensive and harmonious diet. Some of them are required in such minute quantities (the sub-micros) that they are not included in most nutrients on the market. However, laboratory tests have demonstrated an important overall improvement in a plant’s health and resistance to pests when those elements are added.

Bio Essentials

ABOUT CHELATES: All the elements included in Bio Essentials are chelated.

A chelated element is released to the plants only when it becomes less abundant in the nutritive solution. This way, the chelate not only maintains a stable level of the nutrient, but it also protects the plant from an unwanted accumulation of harmful salts.

When plants are rapidly growing, they absorb a lot of elements from the solution, and this destabilises its pH. The faster the growth, the wider the imbalance. This is why it is essential to have a good quality buffer that helps stabilise the pH. In the same process, the buffer will also help to control the level of calcium in the solution. An important feature in the case of hard water.

All the elements included in Bio Essentials comply with the European regulation on organic agriculture.

Bio Essentials can therefore be used in organic gardening.

FLORAkLEEn®salt deposits clearing solution

FloraKleen is a clearing solution unique within this industry. It can be used at any time throughout the plant’s life.

FloraKleen is formulated to remove fertiliser residues that can accumulate over time in hydroponic systems, growing media and potting soils. It is safe for use in all systems and media while plants are growing. It can also be used between crops to clean accumulated salts from the systems. Contrary to other products on the market, FloraKleen is not enzyme based, and uses a completely di#erent technology. Its high concentration and low price make FloraKleen the economical choice for maintaining your plants in both hydroponics and soil based environments.

During cultivation, FloraKleen: dissolves accumulated fertiliser salts. reduces plant stress from excess and imbalanced nutrients. breaks nutrient bonds that attach fertiliser salts to growing media, therefore correcting nutrient lock-out. nourishes the microbial life in the substrate.

Use FloraKleen each time you purge your hydroponic system or potted plants from excess salts that can accumulate as a result of regular fertiliser application.FloraKleen is also an excellent $nal "ush: Use it a few days before harvest to terminate maturation and promote sugaring.

FloraKleen

APPLICATIONS: Hydroponic systems

When changing nutrients: Mix 1.5 to 3 ml / L of water. Use a milder solution for young or fragile plants, and a stronger solution for more established plants, close to harvest. Re-circulate in your system for 48 hours with FloraKleen alone before adding your nutrients. Final flush before harvest: 1) Alone - Drain old nutrient solution and discard. Refill hydroponic reservoir with fresh water and mix 3 ml / L of

FloraKleen. Run this solution during the last day or two before harvest.2) After Ripen* - Add 3 ml / L of FloraKleen during the last two days before harvest to increase the sugars level in your crop.

Potting Soil & Soilless Mixes1) Alone - Every fifteen days fill a watering can with fresh water and add 1.5 to 3 ml / L of FloraKleen. Drench until there is

runoff from the bottom of the pot. Resume your regular fertiliser schedule with the next watering.2) After Ripen* - Add 3 ml / L of FloraKleen during the last two days before harvest to increase the sugars level in your crop.

* FloraKleen and Ripen work together in perfect synergy.

pH REGuLATORSOur unique concept of pH control allows you to adjust and stabilise your pH level, even in presence of fast growing plants.

Use your regulators from seedling to harvest. pH Up and pH Down are adapted to all stages of a plant’s life.

pH downpH Down is not an ordinary acid, but an exhaustive, complex and precise formula. The acidity and alcalinity levels of a nutritive solution have an important impact on the solubility of mineral salts, and the capacity of plants to absorb them. There is no such thing as an ideal pH. A high range favours cation intake and a low one favours anion intake. So every chosen pH is a compromise. The usual safe range recommendation is from 5.5 to 6.5. Our advice is to stay on the low side: from 5.5 to 6.2 (see p. 45).

pH Down includes organic regulatorsUnlike the pH regulators generally available on the market, pH Down is not a common acid. It is a precise formula that regulates, feeds and buffers your nutritive solution all at once. Together with a balanced blend of acids, we incorporated organic buffers to stabilise pH and help control calcium in hard water situations. Use it when preparing the nutritive solution to reduce the pH level. Thanks to its buffering capactiy, the level will remain stable until you renew your solution. Adjust it from time to time to keep good control of pH.

pH uppH Up contains silicateTo raise the pH level this solution is especially useful to growers using Reverse Osmosis or demineralised water. pH Up contains silicate to improve your plant’s environment.

Silicate deficiency can be a limiting factor in hydroponics. Because of its low solubility, it is difficult to put enough of it in the solution. This is why we incorporate it in our products wherever we can.

dry pH downpowder form

A unique product in the industry: harmless as long as it is dry, it becomes a potent acid when diluted in water.

pH regulation is an essential practice for all growers. It makes mineral salts available and stabilises chelates. Two primary conditions for a good absorption of nutritive elements by a plant (see p. 45). To do so, different brands of acids are manufactured in the industry. Some of them are highly concentrated and can be dangerous, depending on their formulation.In several countries, such as Switzerland, the law restricts the sale and handling of these products. In order to sell them, a retailer is submitted to a series of mandatory requirements. Moreover, for shops who offer mail order, sending liquid acids by post is a risky matter, sometimes restricted by the postal authorities.

pH Test Indicatorfast and reliable testsOur pH Test Indicator is perfect for easy testing. It covers a wide range from 4.0 to 8.5. Simply fill the test tube half way with nutrient solution, add two drops of pH Test Indicator, shake and observe the resulting colour. Compare with our colour chart to check your pH level. Good for up to 500 tests.

Very reliable, simple to use and economical, the pH Test Kit advantageously replaces an expensive pH meter.

The first application of this product is, of course, pH regulation. But due to its strong concentration and high phosphoric acid content, it can be used to disinfect and clean growing systems, irrigation lines and substrates. At homeopathic dosage, it can be used as a foliar spray after an insecticide treatment to clean the leaves while feeding the plant.

Dry pH Down also brings a certain amount of essential nutritive elements to a plant, during its entire lifecycle: Nitrates in a form slowly assimilated by a plant and harmless to the flowering process. Phosphates for flowering and also for healthy roots, lush foliage and harmonious growth. Plus some magnesium, sulphur and micro-elements.

Plants are grown within a chamber filled with clay pebbles. The growing chamber is suspended above a reservoir filled with nutrient-enriched water. An air pump drives the nutrient solution up through the “pumping column,” to the drip-ring, where it then drips down through the clay pebbles. This infuses the nutrient with oxygen and constantly bathes the roots, stimulating the plant to grow like you have never seen before!

Technically similar to the AquaFarm, the WaterFarm differs only in size and price.

The essentials of successful gardening

LightThe amount and quality of sunlight that your plants receive will also a# ect their growth. Seasonal variances, exposure and shadows from buildings and trees must be taken into account when setting up a garden. If arti$ cial light is to be used, it must be of a robust spectrum and su" cient intensity to satisfy the needs of the plants without overwhelming them or drying them out. Di# erent plants and di# erent phases of growth require di# erent light spectra and intensity. Light supplies the energy used in photosynthesis, which is one of the most fundamental plant processes.

AtmosphereThe atmosphere a# ects the growth and life of plants dramatically. Plants require lots of fresh air, so growers who are using greenhouses and indoor facilities must supplement their air! ow with fans. The temperature and relative humidity have a major e# ect on plant physiology and growth. Both photosynthesis and transpiration are dependent upon proper humidity, temperature and air circulation. Plants can survive in a wide variety of atmospheric conditions, but to truly thrive they must have plentiful fresh air and proper temperature and humidity. The ideal temperature and humidity for your plants is between 18 and 32°C and 40% to 80% relative humidity.

GenesThe genetics of your plants will play a major role in the outcome of your garden. As the plant goes through its life cycle it can sometimes be di" cult to assess whether it is responding to its environment, or whether it is following the instructions written in its DNA. With the rise of genetically engineered crops, the choice of which varieties to grow can become a charged issue. We have an ethic at GHE, which is to promote growth and ! owering by improving the nutrition of the plants. Therefore, our products contain no hormones or synthetic precursors of any kind. The amazing results that you experience with our products are not due to a manipulation of the metabolism of the plant, they are merely the best expression of its genetic make-up promoted by comprehensive, holistic nutrition.

nutritionPlants need nutrients to grow. GH has several nutrients which provide all of the elements required by plants. These fertilisers contain an ideal blend of macro and micro nutrients, and can be adjusted to suit the needs of the plant based on its age and growth stage.

To boost plant performance, successful gardeners add supplements to the nutrient solution. These additives can improve plant vitality, enhance !avours and increase yields. Since these nutrients and supplements are absorbed through the roots of the plant, optimum nutrition requires strong and healthy roots. Proper nutrition is a major component of healthy, thriving plants.

WaterThe quality of the water that plants receive will a#ect their health and vitality. Tap water can contain harmful additives, such as chlorine, and even natural well water can contain an excess of minerals or have an extreme pH. A surplus of many common elements in water can cause a chain reaction in a nutrient solution, resulting in many of the vital elements fusing together and becoming unavailable to the plant. Testing your water will inform you if your water is an issue.

If your problem is excessive minerals, using the hard water versions of our nutrients might be su"cient. Truly problematic water must be $ltered and pH adjusted before being used for plants.To know the quality of your water, ask for an analysis from your water supplier.

InsectsUnfortunately for gardeners, there are a host of organisms which survive by destroying plants. These range from microscopic bacteria, viruses and fungi to larger organisms such as insects and arachnids. Cleanliness can help prevent pests from arriving. By keeping garden tools and surfaces sterilised, destructive micro-organisms will have a harder time gaining a foothold. Moist, warm and damp conditions are favourable to developing mould and mildew, so avoiding condensation and ensuring su"cient air circulation will help keep these undesirables away. Larger pests require a more aggressive approach. There are many products available which assist in the eradication of these invaders, but cleanliness is a good start in managing pathogens and pests.Used as preventatives, products like BioProtect (that stimulates the immune system), Mineral Magic (that strengthens the plant structure), or Urtica (that kills an amazingly wide range of insects) are very e"cient in improving plant resistance.There are also integrated pest management (IPM) techniques which use natural predators to $ght harmful insects. The e#ectiveness of IPM is now well proven.

GHE

Heat and nutrientsArid, bright, hot environments can have an impact on nutrient solution. As the solution loses water through evaporation and plant transpiration, nutrient strength increases. When growing conditions are more intense, using a less concentrated nutrient solution and monitoring nutrient strength with a meter can help prevent overfeeding. As nutrient solution becomes warmer in hot weather, it loses its ability to hold dissolved oxygen, which is essential for root health. When hot weather strikes, monitor the solution temperature and keep it below 24°C or use a BioFiltre.

nutrient strength and metersNutrient strength is a key factor in proper plant nutrition. Although the recipes GH provides you with should create nutrient solution at the proper strength, there are many environmental factors which can cause nutrient strength to change. A nutrient strength meter is an essential tool for the advanced grower.There are two di#erent types of meters which measure nutrient strength - PPM and EC meters. Both types make the same measurement, but then present the result in di#erent units. Nutrient strength is measured by passing an electric current through the solution; the more easily electricity travels through the solution, the stronger it is. An electrical conductivity meter (EC) will give this result as an electrical value, such as a milliSiemen (mS). This number is directly related to the strength of the nutrient.PPM meters measure the conductivity of the solution, and then attempt to estimate the actual parts per million. The problem with this method is that di#erent meters may use di#erent scales to convert EC measurements to PPM readings, so two di#erent PPM meters could read drastically di#erent values in the exact same nutrient solution. In Europe we use EC meters, which simpli$es things a lot.Whichever meter you choose, it is very important to use a measuring device, in order to track changes in nutrient strength and make decisions and adjustments which will contribute to success.

advanced growing techniques

digital meters: Ec & pHElectrical meters are a fast way to control EC and pH.To make sure your meters remain accurate regularly test them with calibrating solutions.

Quick tips for reverse osmosis users:For those who use reverse osmosis $lters, here is a great tip to bu#er your water and help stabilise the pH. There are two ways, and both are e"cient:

easy steps: 1. First increase your pH up to 10.0 with pH Up or potassium carbonate. 2. Then bring it down to 6.0 with pH Down.

In both cases you’ll obtain water well adapted to hydroponic nutritive solutions, while avoiding untimely pH !uctuations.

Use our pH adjusters to raise or lower pH as needed. Adjusters are available in liquid form (pH Up & pH Down) or in powder (Dry pH Down). Add regulators gradually to avoid overshooting.


GHE

pH and nutrient availabilityThe pH of a nutrient solution describes its acidity or alkalinity. Although extremes of pH can damage roots, the primary reason that pH is relevant to growers is that it a#ects whether certain elements in the solution are available to the plant or not. Speci$c nutrient de$ciencies can arise in a well balanced nutrient solution if that solution exceeds the optimum pH range. Therefore, it is bene$cial to your plants to monitor and adjust pH as needed to ensure complete nutrient availability. Many factors work to change the pH of your nutrient, including microbial activity, atmospheric interactions and recirculation.

For best results regularly check pH to ensure that it does not exceed the acceptable range. Keep nutrient pH between 5.5 and 6.2.

deficienciesHydroponic nutrients contain all elements needed by plants. Under normal circumstances, all elements should be available and nutrient de$ciencies will not occur. A pH imbalance can cause nutrient de$ciencies by creating mineral interactions. Hard water or incorrectly mixing nutrients directly together will also contribute to pH problems. If you observe signs of a speci$c nutrient de$ciency while using high-quality nutrients, examine environmental factors $rst.

advanced growing techniques

Liquid pH testersA liquid pH indicator is the most reliable and econo-mical way to check your pH level. With a liquid pH test indicator, you can also regularly validate the accuracy of your pH meter, and make sure it is working properly. Remember, it only takes a few hours to kill a crop if your digital meter gives you an incorrect reading.

Add two drops of liquid pH Indicator to half a tube of

nutritive solution. Compare with the colour chart

provided to identify your pH.


GHE

In soil or in hydroponics, hydroponic nutrients provide the ultimate in comprehensive and customisable plant nutrition.

Why use hydroponic nutrients?

Providing superior results in both soil and hydroponic gardens, hydroponic nutrients are mineral-based plant food which provide complete and total plant nutrition. Because hydroponic systems do not use soil, they rely on the nutrient solution to provide all the elements needed by the plants. As a result, hydroponic fertilisers, unlike most commonly available plant food, must contain the entire spectrum of necessary elements, making them a robust and complete nutrient source suitable for all gardens.

Typical Fertiliser: Unsuitable for HydroponicsThis fertiliser only provides partial nutrition and must be combined with other fertilisers and soils to provide complete nutrition. (In this case we recommend using Bio Essentials.)

Hydroponic Nutrient: Full-Spectrum Plant NutritionIn a hydroponic system or in soil, this fertiliser will ensure that everything the plant needs will be right at its root-tips.

The nutritional needs of your plants will change throughout their lifetime. A seedling needs a completely di#erent nutrient than a !owering or fruiting plant, and due to their precise composition and modular components, hydroponic nutrients can easily be tuned to match the needs of a plant at any stage of growth. In addition to supplying complete nutrition, hydroponic nutrients are also easily customisable and adjustable to match the changing needs of your plants.

In soil and in hydroponics, supplements add essential qualities to the diet of your plants.

The role of supplements

Although a properly mixed, high-quality, hydroponic nutrient will provide everything a plant needs to thrive, plant performance doesn’t end with supplying just the necessities. Plants cannot live without nutrients, but nutrients alone will not unlock their full potential. Even though supplements may not contain “food” for a plant, they improve a crop by performing such functions as introducing essential organic compounds, accelerating nutrient uptake, boosting ! owering, protecting the root-zone, activating the immune system, reinforcing the plant structure and clearing excess and unused nutrients. Enhancing a garden is easy when working with the supplement options available from General Hydroponics.
