What Changed in the Secret Jardin DR90 3.0
The frame, mostly. Tube diameter went from 16 mm to 19 mm, which Secret Jardin measures as 26% more rigidity. The corners were re-engineered to match. A five tube concept replaced the older assembly, so spare parts now cover the whole range rather than one size.
Fitting a DR90 Grow Tent Into a 3 by 3 Space
Footprint is 90 by 90 by 185 cm, or about 36 by 36 by 73 in. That is a nominal three by three with a little over six feet of headroom. That headroom decides whether a fixture and a filter both fit above the canopy. The frame carries up to 30 kg, 66 lbs of lighting and ventilation. Seven ports are cut into the walls: one for extraction, two for intake, two for cables and two for cool tubes. Lining is 95% reflective hammered mylar on 210D fabric. Secret Jardin rates that at 2.5 times the tear strength and three times the abrasion resistance of the older cloth. A webbed interior fabric handles light proofing, and a waterproof tray covers the floor. It goes up in minutes, by one person, without tools.
