For committed growers, the reference series Dark Room from Secret Jardin offers a lot of growboxes and accessories at fair prices. With a floor space of 2.40 x 1.20 meters (2.88 sqm) this grow tent has enough space for a lush indoor grow. An easy to understand assembly instruction is of course included in delivery.

Cost-effective with well thought-out concept

With the Dark Room series (version 4.00) Secret Jardin has developed a series of growboxes with a great price-performance ratio for advanced growers. The boxes are solidly manufactured and fulfill all functions you can expect from a modern grow tent. Dark Room grow tents are of course 100% lightproof and the new 19 mm support tubes can hold up to 15 kg. The Secret Jardin Dark Room DR240W has a total of 4 doors and 2 windows. Due to the 6 ventilation connections you can realize almost any exhaust air concept. Furthermore the growbox has 2 openings for cooltubes and 4 cable openings. The hammerblow inner coating of the Dark Room Growboxes is completely made of Mylar with a reflectance of up to 95%.

Many accessories included in delivery

In addition to the growbox, Secret Jardin offers you with the Dark Room series a lot of practical accessories to perfect your grow. Especially interesting are a set of Space Boosters, horizontal poles that prevent the tent walls from bulging inwards and a matching WebIT (scrog net). CableIT (cable holder), HookIT (lamp holder), StrapIT (filter holder) and PocketIT (tool bag) complete the offer perfectly.

Perfect illumination with 2x 600 Watt NDL or 2x 400 Watt LED

For the perfect light supply of your plants we recommend a set of two sodium vapor lamps (NDL) with 600 watts each for this box. For example the inexpensive GIB Lighting Flower Spectre. If you prefer to work with energy-efficient LED grow lights, 2x 400 watt LED or 4x 200 watt LED are the right choice for you.
