Secret Jardin Dark Room DR300W R4 — 2.97m × 1.5m × 2.17m Rectangular Tent

Secret Jardin Dark Room DR300W R4 — Pre-Equipped 2.97m × 1.5m × 2.17m

The long-and-narrow version of Secret Jardin's 3m-wide Dark Room — same premium R4 build quality and pre-equipped spec, but in a 3m × 1.5m footprint. Perfect for long, narrow rooms (spare bedrooms, garages, cellars) where a 3m × 3m square simply wouldn't fit.

Why growers choose the DR300W R4:

• 2.97m × 1.5m rectangular footprint — fits 8-10 plants along the length, ideal for narrow spaces
• 2.17m tall — taller than the standard DR300 R3, better for tall plants and canopy management
• R4 Pre-Equipped upgrades — newer tubes, stronger corners, premium Mylar lining
• Ideal rectangular tent for LED light layouts — pairs beautifully with a Lumatek Zeus 1000W Pro (rectangular coverage) or two 600W fixtures in a row
• Premium Secret Jardin reliability — built to outlast budget tents several times over
• 5-tube parts concept — simple to source replacement poles if one gets damaged

Who it's not for:

Check your available length — 3m is substantial, needs at least 3.2m clear wall-to-wall. For truly square flowering canopies, the standard DR300 (3m × 3m) is better. For shorter spaces, the 2.4m-long DR240 range fits better.
