Secret Jardin Dark Room DR300W R3 — 3.0m × 1.5m × 2.35m (Tall Rectangular)

Secret Jardin Dark Room DR300W R3 — 3.0m × 1.5m × 2.35m

The tall, rectangular R3 version of Secret Jardin's wider Dark Room range — 3m long, 1.5m wide, and a generous 2.35m internal height. For growers with narrow but tall rooms (typically garage conversions or cellars with high ceilings) who want the DR300 width without the full square footprint.

Why growers choose the DR300W R3:

• 3.0m × 1.5m × 2.35m — 4.5m² rectangular footprint with exceptional 2.35m headroom
• Tallest in the 1.5m-wide range — room for SCROG at height, tall sativa strains, or very high-hanging lights
• R3 standard spec — tent, frame, Mylar — tent-only package for growers with existing extraction kit
• Rectangular layout — fits 8-10 plants in a line, ideal for long garages and cellars
• Secret Jardin build quality at R3 pricing — the premium European tent brand, at the non-Pre-Equipped price

Who it's not for:

2.35m height needs a 2.45m+ ceiling — won't fit in standard UK domestic rooms with 2.4m ceilings. For square layouts or shorter ceiling rooms, the DR240 R3 is better. For the newer R4 tubes and corners with included Pre-Equipped accessories, step up to the DR300W R4.
