  • Highly reflective interior coating - maximum light output
  • 100% lightproof with strong frame
  • extra high box for extra large plants
  • with many practical accessories

The reference series Dark Room from Secret Jardin offers all highly motivated growers a lot of grow box and accessories at fair prices.

With a footprint of 3.00 x 3.00 meters (9.00 square meters), the DR300 offers you plenty of space for a successful indoor grow. The height was raised to 2.35 meters, so even very tall growing plants have plenty of room. Easy to understand assembly instructions are of course included in the delivery.

Price-effective with well thought-out concept

With the Dark Room R3.00 series, Secret Jardin has developed a range of grow boxes with a great price-performance ratio for advanced growers. The boxes are solidly made and fulfill all the functions you expect from a modern grow tent. Grow tents of the Dark Room series are of course 100% lightproof and the new 19 mm support tubes hold up to 15 kg payload. The Secret Jardin Dark Room DR300 has two large windows in the front and two in the back. The 8 ventilation ports allow you to realize almost any exhaust concept. The hammered interior coating of the Dark Room grow boxes is made entirely of Mylar with a reflectance of up to 95%.

Many accessories included

In addition to the grow box, Secret Jardin offers you with the Dark Room series a lot of practical accessories to perfect your grow

Of particular interest are a set of Space Boosters, horizontal poles that prevent the tent walls from bulging inward, and two matching WebIT 300 (scrog nets). CableIT (cable holder), HookIT (lamp holder), StrapIT (filter holder) and PocketIT (tool bag) perfectly round out the range.

Ideal illumination with 6 x 600 watt grow lamps

For plant lighting, we recommend 6 x 600 watt NDL for this grow box, for example, the Osram Plantastar NDL for the flowering phase or the Philips SON-T PIA Green Power for the vegetative phase. If you prefer to work with LED grow lamps, we advise you to use 8 pieces SANlight Q6W S2.1 Gen2 with 245W each. For ventilation we recommend our perfectly matched ventilation set 1030 silent including a powerful tube fan and matching activated carbon filter for NDL or a Torin MDF softbox.
