These tents are designed by Mammoth and Gavita, in synergy with the new Gavita Small Room reflectors. The result of combining this tent and reflector combination: a 1 and 2 light grow room with optimal light uniformity. The flooring of the Mammoth Gavita tents is 100% waterproof, preventing leaks and providing an excellent built in water tray. Each tent has a heavy duty frame built with 22 mm steel poles, a rugged canvas exterior and a reflective mylar interior providing a light proof growing environment.
