ya, well im using a huge walk-in closet, i just sectioned part of it off and lined the walls with an emergency blanket, i can always make the space bigger, but im not too sure what would work out better... i think i will mix both, ill use the 400W HPS from above and put flouro tubes up and down the sides and see what kind of monsters i can get :jointsmile: i usually flower when the nodes start alternating which with the last 10 or so plants was about 2' tall. i want to maximize my yield as much as possible, with this grow i will be LST'ing like crazy, then next grow ill probably try a scrog grow.
