i have a shelf greenhouse type thing. its a really cheap unit.. the plastics extremely thin.. i mostly just want to use it to try and make one lame ass attempt to try and keep the rats away from my 2 plants....., so.... my shelf greenhouse is plastic all the way around.. seems like it gets freakin hot and humid as shit in there.... is that a benefit. or is that ok? im gonna keep the zipper open for venting untill notice... i figured it would be fine at night but it seems very hot inside this small shelf greenhouse. and its only like 80 f here.. anyways.. its not 100 percent sealed at the bottum or anything its just sitting on some fairly leveled out ground but.. wow it felt so hot when i unzipped it and stuck my hand in there. i was like holy fuck.. the plants looked fine but i have it unzipped now.. untill night.... night time i wanna keep these ghetto rats away.. theyll fuckin eat damn near anything.. if this fails then its in the CFL cabinet the plants go
