Yeah, those are nice but nothing a couple sheets of plywood and some flat white paint can't do too and for far less $$$! I use plywood quartered and painted flat white as portable walls in my room so the actual walls don't get used in the grow and any space can be turned into a grow room. They can be moved practically anywhere and set up only takes a few minutes. "L-brackets" with lg wing nuts hold them together and can be made into any shape or size to fit your room and needs.
