The ventilation is pretty poor, but thus far does not seem to be holding her back. There are holes in the top bucket, an air gap around the bottom two buckets and I usually have the top bucket sitting on 1/2" sticks for another air gap. At night the top bucket comes off. If she starts showing signs of stress, then I will have to kluge up some sort of computer fan. It would have to go on the outside as there is no room left inside. I will take a look to see what I an come up with because it does not yet look ghetto enough. :rastasmoke:

This is the biggest plant I have ever had in here. If I were to do something similar again, I would use a 50 gallon Rubbermaid or similar trash can with two vent fans. This was initially designed just as a convenient way to veg for 1- 4 weeks and /or do lighting experiments and no more.
