Sun Hut? The Big Easy? Grow Tents are enclosed greenhouses that have a durable, lightweight, and light-tight 190D outer material with a highly reflective interior. The Big Easy? has reinforced stitching in high-wear areas and has a new improved zipper, creating a rugged and durable grow environment. All sizes have a “U” shaped rear door for total access to your growing space. The frame of The Big Easy? consists of galvanized steel poles and unique quick connect molded plastic corners. With these two features combined, the assembly of this grow tent is both quick and simple. Other features include 10 in duct ports, high and low lamp/power cord ports and a tray bottom. The 2 ft x 4 ft, 4 ft x 4 ft, and 4 ft x 8 ft models are large enough to fit the largest plastic grow trays on the market. Note: model numbers identify the approximate cubic feet.
