ok. I was wondering, would white poster paper work instead of paint? I'm going to grow in an area similar to a closet but it houses an extraction pump for the plumbing in the house. Its basically a sump room but it is very open, i just placed some drywall over the openings to an extent so noone can look directly at my plant in case i have company. it will be on concrete so i wont have to worry about water damage. and would using 2 desklamps with cfls and one 18 inch florescent light be sufficient for one plant or should i get more light? any input would be great.
