The room has sloped ceilings (15ft in center) and is 15ftx20ft. My questions is do I build a self contained system for veg&flower and have a small area for clones&seedlings ect? Or do I just spend the money from constuction and invest it into lights and use the whole space with natural air circulation whitch it has in the eves of the roof? Then I would just use a curtian or something for starting the babeis W/floros or something. Im going hydo,not sure on the system yet but I am leaning towards something like K9 used. The only thing with that is I can't find those damn sprayjets that mount into the pvc anywhere! I tried Home Deblow and a couple of garden shops.Anyone have a better idea of where to find them? What about useing one of those garden hoses with the holes across it instead of the pvc with the fittings across the ABC? Or how about one of those pond fountain sprayers that could sit in the bottom of the ABC ? PEACEOUT!
