Ok someone please help! I want to get the supplies and start working tomorrow. Since I have a whole closet to work with I have some options: a.) just grow the plants directly in the closest. Light proof the closet and surround the plants by reflective material. Also, need to make sure temp stays ok and can control smell. b.) build a small box in the closet. I would want it to be cheap, easy to build, and light. I was thinking of making the frame out of either pvc and covering with foam or/and reflective material. I could alsobuild the box out of foam insulation I found at home depot????? This seems easiesst of all. Just secure all the sides/corners and paint white. Would this work?? Is it better to just use the closet or build and actual box. which would be better as far as smell and temp control?
