Secret Jardin has always been committed to the ongoing refinement and testing of their products, which is one of the things that has made their range of grow tents so user-friendly. Always open to feedback from experienced growers, the Dark Room line of grow tents has undergone a series of revisions, leading to the upgraded R3.00 range. This includes the new and improved Secret Jardin Dark Room 4' X 4' X 6.7' Grow Tent.

One of the great new features of the Dark Room 4' X 4' X 6.7' is the highly reflective interior lining which helps to ensure that an optimal level of light from the grow lamps will reach the plants. The reflectiveness comes from the mylar plastic film, which also adds a layer of waterproofing to the tent interior. Mylar is a chemically stable product that was originally used by NASA in the construction of satellites. Now a favorite among grow tent manufacturers, mylar helps to make the Secret Jardin Dark Room grow tents virtually tear-free and boosts their resistance to abrasions. The exterior covering is a heavy-duty black canvas that helps to create a 95% lightproof interior for the garden.

The Secret Jardin Dark Room 4' X 4' X 6.7' has been designed with multiple socks and windows to make it easier for grow light systems and ventilation equipment to be installed. The Dark Room 4' X 4' X 6.7' grow tent also comes with a PocketIT tool pouch (which is height adjustable), a filter strap and grow light hook, plus 15 x CableIT cord clips which help in getting the grow tent set up neatly (you won’t have to worry about electrical cords dangling everywhere). These little added extras are a nice touch from Secret Jardin, as they all contribute towards a more convenient and fuss-free setup.

Growers who may have previously purchased the original line of Dark Room grow tents will notice that the frame on the Revision R3.00 is sturdier (tested as 26% more rigid). This is due to an increase in the frame diameter from 0.63” up to 0.75”. However, the easy to assemble design of the frame has stayed the same, so growers can still set up a Dark Room grow tent by themselves, in less than 15 minutes, without needing any tools.
