BEST FRAME IN THE INDUSTRY: This grow closet is constructed using thick, 3/4" diameter powder-coated metal poles for rock solid stability (many competing tents use flimsy and thin 1/2” poles). In addition, we provide a crossbar to hang your lights and ventilation. MAX-EFFICIENCY SHELL: Crafted entirely from durable, tear-proof 600D nylon (much thicker than 400-series nylon), double stitched throughout and backed with top-grade, highly-reflective, maximum-efficiency Mylar film. This 100% light-proof, space-age surface returns practically all light back to the plants to increase growth without additional energy consumption. INTEGRATED VIEWING WINDOW: Check in on the condition of your plants and monitor growth without opening the main door. TOP OF THE LINE FEATURES: All vents are double-socked to cinch up tight, keeping odors and CO2 inside and pests and ambient light outside. For easy maintenance, also features a removable floor insert made with the same upgraded Mylar-backed nylon as the rest of the tent. Large, zippered door allows for easy access and convenience, and is built with the toughest zippers we could find to provide secure protection and long-lasting use, without catching or snagging. NO TOOLS REQUIRED: Place your indoor grow tent anywhere - in an apartment, condominium, greenhouse, or any underutilized space (just follow proper safety guidelines anytime you grow indoors). Assembles in minutes without tools. INCLUDES: Helios Hydro grow tent, premium frame with one cross bar for equipment hanging, removable floor insert, filter straps and easy-to-follow instructions.
