This Darkroom II (DR II) is the successor of the Secret Jardin Darkroom (DR) series. Jardin Secret has done her best to make as many improvements to the development of the grow tent as possible. The corner pieces of the DR II are three times stronger than that of the old DR series. Also, the canvas of the DR II is manufactured from M210D material, which is 2.5 to 3 times more wear resistant and stronger than the old 190D canvas that was used for making the DR series. The inside of the tent is made of mylar, which reflects up to 95% light. Also, the luminance of the tent improved, this is achieved by including the use of better stitching hems at the break of all in-and outlets of the tent. DR II, with the exception of the DR-60 II, has larger and sometimes more inlets. There are also additional inputs and outlets for cool tubes. The steel poles of the DR II have a thickness of 0.7 mm and 15.9 mm in diameter. All Darkroom II tents are equipped with a waterproof, removable tray. In the mylar on the inside, an anti-copy Secret Jardin logo is placed. Also, all DRII tents are equipped with a serial tracking numbe. All DRII tents include a carry bag. All these tents are equipped with two suspension tubes. Each bar has a capacity of 20 kg, but the maximum total weight of the two beams must not exceed 30 kg.
