I have a single 120V 60HZ grow light that I am wanting to use as a terr. light. I'll be using a ten gallon terrerium. I'll will turn the light on when I get up in the morning(around 7:30-9:00) and turn it off when I go to bed at night (anywhere from 9:30-11:00 though I usually 10:00) Will this work. Oh, also will it help to wrap the back sides and maybe the top with tin-foil?
