We have a lot of experience growing a diverse range of plants under different combinations of LED grow light colors. In our (and others') experimentation, it is clear some plants such as green leaf lettuce are capable of growing with extremely limited spectrums (i.e. with only red light), although the plants do not grow "normally"-- they exhibit significant differences from the same variety of plants grown in natural sunlight. Many plants will not grow well with limited colors of light (even with red and blue included), and without key spectra, normal pigmentation and other secondary metabolites (such as vitamins, compounds related to flavor, THC and CBD, etc.) may not be produced by the plant in normal quantities, or at all. However, if all necessary spectra are included in a light, all plants will grow optimally and produce desired secondary metabolites.

Black Dog LED's Phyto-Genesis Spectrum® has been painstakingly developed to grow plants of all different types. By going far beyond the "bare minimum" spectra required to just get plants to survive, we successfully grow plants of all species and strains. We have grown over 400 different species of plants under our lights, with representatives from most of the major divisions of the plant kingdom (Plantae), separated by hundreds of millions of years of evolution -- and the results are always the same: plants thrive under Black Dog LED.

For the record, we have tested species from the following divisions of plants:

• Chlorophyta (green algae)
• Marchantiophyta (liverworts)
• Bryophyta (mosses)
• Lycopodiophyta (club mosses)
• Pteridophyta (ferns, whisk ferns and horsetails)
• Cycadophyta (cycads)
• Ginkgophyta (Ginkgo)
• Pinophyta (conifers)
• Magnoliophyta (flowering plants [including Cannabis])

The 3 divisions we have yet to test are: Charophyta (stoneworts / desmids), Anthocerotophyta (hornworts) and Gnetophyta (gnetophytes).
