HERE is the link to my thread for making a spectrometer for anyone wanting to jump in on that. I'm still stoked on this martian method tho, being it is what got me interested in the spectrums of lighting in the first place Mother, I'm still curious if you saw my last post pertaining to the lighting schedule, and about those last pics.. In the center pic the fans look like they only have one or two leaves on them are they pruned to let more light through the canopy or what am I seeing there?
