YES LINE WITH FOIL OR WHITE PLASTIC.REMEMBER IF USING FOIL USE THE DULL SIDE FACING PLANTS NOT THE SHINNY SIDE HOPE THIS HELPS MR.H
MR.H Reviewed by MR.H on . Rookie Grower 1. How much more on your energy bill for a 400 watt Sodium light? 2. If I were to create a 4x4 box in a room, would I really want to line it with tin foil on the inside? Is that 400 watt light enough for 6-8 plants? I worry about the neighbors seeing these lights on, thats why I wouldnt want to make the whole room a grow room. Any suggestions to get me going. Rating: 5
