Secret Jardin Dark Room DR300W, 300x150x235cm

  • highly reflective inner coating - maximum light yield
  • with many practical accessories
  • extra high box for particularly large plants
  • rectangular version - for alternative room use

For committed growers, the reference series Dark Room from Secret Jardin offers a lot of growboxes and accessories at fair prices. With a footprint of 3.00 x 1.50 meters (4.5 square meters), the DR300W offers you a lot of space for a successful indoor grow. Its rectangular shape creates an alternative for areas where a square box does not fit. The height has been raised to 2.35 meters, so even very tall plants have plenty of room. An easy to understand assembly instruction is of course included.

Cost-effective with well thought-out concept

With the Dark Room R3.00 series 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 expect from a modern grow tent. Dark Room Series 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 DR300W has two large windows each in the front and back. With the 8 ventilation connections you can realize almost any exhaust air concept. 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 two matching WebIT 150 ( Scrog nets). CableIT (cable holder), HookIT (lamp holder), StrapIT (filter holder) and PocketIT (tool bag) round off the offer perfectly.

Perfect illumination with 3x 600 Watt Grow lamps

For plant lighting we recommend a set of 3x 600 Watt for this growbox, for example the Osram Plantastar NDL for the flowering phase or the Philips SON-T Green Power for the vegetative phase. If you prefer to work with LED Grow lamps, we recommend 6 pieces SANlight Q4WL S2.1 Gen2, with 165 Watt each. For aeration and ventilation we recommend our perfectly tuned Ventilation set 1030 silent including a powerful tube fan and matching activated carbon filter for NDL or the Ventilation set 800 PRO for LED.
