Looking for a grow tent that fits inside a closet, a spare bedroom or a corner of your garage without giving up build quality? The Dark Street R4.00 from Secret Jardin checks every box: 60x60 cm footprint, 158 cm height, hammered M210D Mylar that bounces back up to 95% of the light from your LED, and full lightproof + waterproof construction. The grow tent designed for indoor cultivators who want a pro setup without taking over the room.

The interior wall of hammered M210D Mylar bounces back up to 95% of the light emitted by your horticultural lamp. The hammered pattern diffuses rays without creating hotspots, evens out PPFD across the entire canopy and accelerates photosynthesis where it matters most.
Doubled stitching, drawstring ventilation socks, light-trap zipper flaps: no light gets in or out of the tent. Critical for respecting flowering photoperiod and avoiding the light-stress that triggers hermaphroditism in sensitive cultivars.
The watertight floor tray clips in within seconds and catches up to several liters of overflow if your reservoir leaks. It pulls out completely for end-of-cycle cleaning, preventing organic residue buildup and disease carryover between two crops.
Six pre-cut ventilation socks (100/125 mm exhaust and intake, plus cable passes) with drawstring closures. You install your extraction kit and carbon filter in under ten minutes, with no DIY tinkering or fabric perforation needed.
The 16 mm steel poles are coated with anti-corrosion treatment that resists the tropical humidity of a flowering room. Crossbars carry up to 30 kg — more than enough to suspend a 200W LED, a carbon filter and an inline fan without flex or sag.
For a 0.36 m² footprint, target between 100W and 200W of real LED draw (not marketing wattage). A quality 120W LED like a Mars Hydro TS1000 or a Samsung LM301H Quantum Board is plenty for 1 to 4 plants in veg and bloom. Above 200W you generate more heat than this volume can dissipate.
How many plants fit in this grow tent?Depends on the method: 1 mainlined plant outyields 4 cramped plants in SCROG. For autoflowers in 11L pots, count 2 to 4 plants. In SOG (Sea of Green) with 5L pots, up to 9 plants in fast bloom. The 158 cm height pushes you toward LST or SCROG with vigorous strains.
Is the inline fan included with the tent?No, the tent ships bare: fabric, frame, removable tray and instructions. You will need to add your ventilation kit (100 or 125 mm extractor, intake or passive vents, carbon filter, ducting), your horticultural LED and pots. BloomLED stocks complete starter bundles if you are building from scratch.
Is the Dark Street really 100% lightproof at night?Yes, provided you fully close the front zipper and tighten the ventilation socks. The doubled seams and the light-trap flap over the zipper prevent leaks in either direction. No light from your LED escapes outside, and ambient room light will not disturb your 12/12 flowering photoperiod.
The Dark Street R4.00 60x60x158 strikes the perfect balance between minimal footprint and pro Secret Jardin build quality: M210D Mylar, lightproof, removable tray, 30 kg load rating. At €95 it is the most cost-effective entry point into serious indoor cultivation in a small space.
