Description
The Secret Jardin DR300 is the largest grow tent we sell and measures a whopping 300 x 300 x 235cm.
Features include:
- Strong, easy to use roof support system capable of supporting up to 30kg
- SupportIT bar to provide extra stability in the centre of the tent
- Tear-proof, highly reflective, light-proof and washable Mylar 210D lining
- New engineered corner pieces that are three times stronger than before
- Two sealable and removable 50cm x 30cm ventilation flaps
- 2 x cable access ports at the bottom, 2 more at the top
- 4 x 315mm mm top vents
- 4 x 315mm bottom vents
- 4 x 250mm Cooltube vents
- Removable floor tray
- Comes complete with the Secret Jardin accessory set, WebIT, Space Savers bars etc
The DR300 is a large grow tent size suitable for 4 x 1000W or 6-8 x 600W lights.
Extraction wise you will need at least 2 x 8 high powered fans for either of the above configurations, to be able to keep summer temperatures under control.
This tent has a very large growing area of 21.2 m2 making it one of the biggest on the market. There are larger tents out there but you then start moving into a price bracket of £1k plus, which for most people is a bit strong.
The tent weighs 48.5kg making it impossible for us to ship via standard courier - it will need to either come on a pallet or be picked up in-store.
We sell a surprising amount of these tents considering their size and have quite a lot of knowledge about the different configurations that work well with them, if you have any questions just give us a call and well be able to put a bespoke kit together for you.

How to use
The tent comes with the Secret Jardin accessory set, WebIT and Space Savers bars. With either light set-up you will need at least two high-powered 8 inch extractor fans to keep summer temperatures under control.
At 48.5 kg it is too heavy for a standard courier: it goes on a pallet, or you can collect it from the shop. We sell more of these than you might think, so call us if you want a kit put together for it. See all Dark Room tents.
