Interesting thought on the plant cover...but it seems like that'd increase humidity around your bud, which, to my unexperienced mind, seems bad.
But know this: where there's a will, there's a way. If you figure it out, you'll be the cat that takes RIU mainstream... 'i remember when he was growing popcorn with cfl's...'
Beyond that, your grow looks pretty cool. I'm a novice, but from what I gather about you, you're a reasearcher, too.
My reasearch says: don't underlight the plants.
I'm making a pleasant place for some plants. I was going to paint it all white, even the floor...but then I read in Jorge Cervantes's Bible, the underside of the leaves do not have the same photosynthesis receptors. On the underside of the leaves are the stomata which do the transpiration for the plant...so don't paint the floor white.
It looks like you managed to not kill that bagseed weed, so I guess it's not the bane of marijuana...but I can't help but think that the plant looks a little skinny.
May I inquire as to your yield and quality?
Also, the calyxs (?) seem like they're way long...they're pretty, but they've grown way beyond the compactness of the bud area...almost like they're streeeeetching for some reason...trying to get pollinated - like a blackroots bar around cutoff time...
I've heard that was a sign of stress, but I forgot from what. Perhaps an OG will catch your post at the top of the mount and hand you the stone tablets containing the ten commandments of chronic.
