Glad I found this thread. I planned on putting T12s on the sides of my closet for better complete lighting, so now I definitely will. I'd imagine it will help a lot because of how close the plants will be to the wall, preventing even more or the light from the top from getting down to the lower branches.
Any law against what I do on this forum would be impeding on my right to freedom and the pursuit of happiness. So unfortunately, I'm forced to play the role of a cannabis grower instead of actually participate in the hobby.
