Does any one else use Mylar slips on the bottom of their plants especially during early development? I`ve found that this effectively doubles my lumen absorption in foliage, but once they grow bigger they tend to be less effective. They also reduce the ammount of water evaporated from your soil, so you don`t have to water nearly as much. The instructions are in my signature, but all you need is glue, some mylar, cardboard, and electrical tape.
