well when it started doing this i only had one of those light that are used to hook onto the hood of cars so you can see i was only using that for my heat now i have a desk lamp in there but it get around 20 degrees here at night time and the only time of the day i can check on my plant is around 3pm-4pm which its usually around 40-50 at that time and i put my hand inside the box and it feels extremely hot so do you think it could really be getting that cold at night time (this is after i put 2 bulbs in there for heat)-----------also is there anyway to keep my plant from getting really tall and just keeping it fat and short i had an idea of tieing it down sideways and seeing what that does but i thought id look into it first
