The Secret Jardin DR300W is a professional-grade grow tent designed for cultivation plants up to 150 cm in height. This tent is very spacious and can handle various types of plants. Built to last, the exterior is made with M400D mylar canvas and stainless steel poles for extra strength. The interior is lined with a silver layer that’s highly reflective and also retains light. The double-flapped zipper offers extra protection against light leaks. This grow tent is equipped with a removable fibered liner water tray and PE600D bottom that lowers the chances for spills and makes maintenance and cleaning easier. The DF25 ducting flanges are optimal for intake and exhaust management, providing odor control and efficient air movement all around the tent.
