The Mammoth Classic+ 90 is a high quality grow tent designed for both beginner and professional indoor growers. Built to last, this tent is covered with a highly protective 600D mylar fabric that’s both durable and light-proofing. This material ensures minimal light leakage and is washable both inside and outside. The frame is made of 19 mm steel poles reinforced with plastic connectors, providing a sturdy structure that can withstand the weight of additional equipment. On the inside, there’s a high-quality reflective material that offers 95% light reflective and retention. The multiple ventilation ports with adjustable cuffs allow more flexible installation of fans and ducting. The assembly is quick and tool-free thanks to the nap-together frame. With a large front door, it’s easy to access the plants.
