Spectrum

We recommend full-spectrum lights unlessyou just need supplemental lighting with aspecific color spectrum.

Two Options White LEDs Multiple colored LEDs

Proponents claim they best approximate natural sunlight and are a perfect combination of HPS and MH light.

Best Option: Pro Max Grow

Full Spectrum White LED Lights

Proponents say white LEDs include too much light in the green and yellow spectrum range.Since this light is not usable by plants, it goes to waste, making white LEDs less efficient.

Multi-Band Full Spectrum LED Lights

We prefer multi-band fixtures.They all (the ones we sell at least) include white light.

Best Option: Kind LED: they have a 12- band spectrum
