One of the newest products to receive an upgrade in the Revision R3.00 line is the Secret Jardin Dark Room 3' x 3' x 6' Grow Tent. Since 2006, Secret Jardin has been dedicated to continually testing and re-working their products, never satisfied to rest on the laurels of their past achievements. As a result, the upgraded Dark Room grow tents are stronger, better equipped for ventilation and now have a 95% lightproof covering.

This fantastic grow tent comes with a selection of useful accessories that will make setting up an indoor garden easier and more effective. This includes obvious items such as a hook and strap to assist with hanging grow lamps, but also less obvious items such as cord clips; these tiny clips go a long way towards improving the functionality of a grow space and making the interior a neater place to work. The Dark Room 3' x 3' x 6'  also comes with a PocketIT tool pouch which is height adjustable for added convenience.

The upgraded fabric covering the tent is a black heavy-duty canvas which provides good insulation for the grow tent interior. This superior grow tent material has a higher resistance to tears and abrasions, an important factor when working in a confined space with sharp gardening tools. The grow tent interior is highly reflective (thereby improving light distribution to the plants) as a result of the mylar lining. This silver film has a high tensile strength and is chemically stable, so growers won’t need to worry about it leaching any harmful chemicals that could have a negative impact on the plants. The mylar is also waterproof, which is great for ensuring that no moisture leaks out of the grow tent and into the surrounding room. As an added precaution, the Dark Room 3' x 3' x 6'  has a removable floor tray that has also been lined with mylar.

The grow tent frame is now sturdier as a result of Secret Jardin increasing the diameter of the metal frame poles (previously 0.63”, now 0.75”). Powder coated for protection against rust, this frame can be easily assembled by just one person, using no tools, in a matter of minutes.
