Romaine Lettuce Experiment Part 2

Nice setup Desyrel for sleep and interesting experiments. I like Zoloft for anxiety the styrofoam Medroxyprogesterone 10mg but I Nifedipine for preterm labor thought roots like it as dark as possible and this material seems to let light trough. I'd like to know how that works out, I might adapt this if it doesn't cause problems (or I'll put some light tight black/white foil-”discs” over the styrofoam. I can't find cheap neoprene sheets to do the trick, they seem to be used in other professional aero systems.
