this is some good shit. Whats up with yall. Curious to see how this one turns out. Is your plant a female and what light cycle do you have her/him on? If it were me I'd use the 400 without anything else. Reduce heat, clutter i dont know just seems the practical way. Oh yeah for peats sake go pick up your plant, probably got dirt on the floor and start slowly tying her down. Use that 400 air cooled or not think your safe in the big closet for a while but if it's already gettin in the 90's where you live go air cooled, besides you can get the plant that much closer. Good Luck, and oh yeah, pick that plant up.
