You should see it with redneck sthealth. That's duct tape up all the widows so not as much light comes out. I show one in my thread (redhair ladies). They have reflectant on the windows so when lights are out you can't see in. They have to be kept where you can controll temps, like house AC or they get too hot.. There water tight so I will keep trying to make a hydro unit with one. You can do much better and cheaper with regular hydro a few flouro's and a cabinet with vents. If you have them laying around, you know sometimes you have to work with what you have.
