you're going to have some challenges cooling that box. you want to make sure the temps are ok before you put plants in thereits 36" high, 20" wide and 17" deep. im looking to extend in the future but that as it is, is fine with me for now.
this is a common problem with small boxes that i luckily do not experience as i grow in a closet. try searching "ventilation" as a tag under the search function. you should find lots about small box ventiation tricks.got any good suggestions on howi can keep the temps down ? so i dnt end up cooking the plant.
