A professional 10x10 grow tent engineered for maximum light efficiency, heavy equipment support, and fully customizable airflow in demanding indoor grow environments.

The Secret Jardin Dark Room 300 v3.0 is built for growers who need a serious, room scale solution without committing to permanent construction. With a 10' x 10' footprint, this grow tent functions like a true grow room, offering tight environmental control, high load capacity, and zero compromises on light containment. The 95% reflective, hammered mylar interior (210D) pushes light back into the canopy, improving uniformity and maximizing usable PPFD across large plant counts.

Designed for high-intensity LED or HID grow setups, the Dark Room 300 v3.0 handles real equipment with ease. Reinforced equipment bars support heavy fixtures and carbon filters, while the fully pre-equipped ventilation layout eliminates guesswork during installation. If you are running full flower cycles, high-density veg, or a perpetual system, this tent gives you the structure, durability, and flexibility to run consistently at scale.

    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.
