i only use one window in my house for CPs and its actually a sliding glass door. the only thing in it are a couple Sarrs(a few more to be added soon), a Darlingtonia, D. rotundifolia, D. filliformis and a D. binata. everything else is grown under lights. Pings, Drosera, Utrics and Genliseas are in my new shelf system on two shelves under lights. a third shelf will be used once i find a 20 gal aquarium for epiphytic Utrics and Hellies(dont have yet but plan on getting some this summer) this will also have its own automated misting system hopefully if i can get some one to drill a hole or two through the glass for me. my Neps are in two tanks at the moment, lowlands in a 75 gal, highlands in a 10 gal. a few odds and ends are stuck elsewhere, usualy among orchids under lights.
