In a small area where I am growing I have some aluminum foil around the area of my plant...do I need to cover the walls, floors, everything etc? It is only a small amount of foil and I know it isn't enough but it is dull side out and it helps it get pretty warm, but it would help if I had details. ~~Ryan~~
u should at least cover the outside of your plants with foil a surface that is painted white works even better though
