Blocks all light from escaping: Made from top-quality materials with all seams reinforced, the Solhydro growing tent is completely light-proof and keeps even odors from getting in. No need for additional flap or tape—just zip the black lining to create a light-proof seal. Top fabric and industrial-strength zipper: Solhydro clone tents are made with 2000D canvas PE material that is double stitched and paired with 99% diamond reflective technology mylar lining. They have heavy-duty metal zippers reinforced with dual leak-proof binding tape. Non-toxic, no odor, anti-aging, and washable! Built with the grower in mind: Solhydro grow closets have special observation windows distributed at 360 degrees, 5 different-sized dual cinching duct ports, a reflective floor tray, 3 side-access doors, and a convenient tool pouch. They are ideal for both professionals and beginners. Sturdy built, long-lasting performance: The tent’s heavy-duty frame is composed of 22mm diameter hardened steel tubes, alloy locking pins, and pure metal-welded corner pieces that bear up to 150lbs of weight. These make the frame of the hydroponic grow tent much secure and solid.
