Spacious 8x8 grow tent with 95% Mylar lining, pro-grade ventilation, and heavy-duty build for full-scale indoor cultivation.

The Secret Jardin Dark Room 240 V4 is a serious tent for serious growers. At 8' x 8' with nearly 6'7" of vertical clearance, this beast is built to handle large-scale soil or hydro setups without breaking a sweat. The 210D hammered Mylar lining delivers 95% reflectivity for superior light spread, while its double-stitched, light-proof canvas and 0.75" steel frame hold strong under intense equipment loads.

This tent was made for growers running 4 HID or high-output LED lights, managing aggressive veg or bloom cycles, and needing clean, efficient air exchange. With 14 duct socks, 8 light holders, and enough floor space to manage canopy like a pro, it’s the go-to choice when you’re scaling up for real yields. If you're ready to turn your grow room into a true production zone, the DR240 is your next smartest investment.

        FAQs

        How do I choose the right grow tent size for my plants?

        It depends on your plant count, lighting setup, and available space. A 2’x4’ tent suits 2–4 plants, while 4’x8’ and 10’x10’ options can handle full cycles for commercial or caregiver grows. Also consider height for light clearance and vertical growth.

        What features should I look for in a high-quality grow tent?

        Prioritize thick canvas material (1680D+), heavy-duty zippers, double cinching duct ports, and a strong steel frame. Also look for diamond reflective mylar, large access windows, tool pouches, and height extension kits for taller plants or lights.
