VIVOSUN 3x3 Grow Tent P336 PRO 36x36x72 — 2000D Lightproof with 100% Reflective Interior and Reinforced Steel Frame

VIVOSUN P336 PRO is a heavy-duty 3'x3'x6' indoor grow tent built with 2000D lightproof fabric, a 100% reflective interior, reinforced steel poles, and user-focused features for stable, efficient cultivation.

Compact yet rugged, the P336 PRO grow tent gives hobbyists and small-scale cultivators a controllable, light-tight environment for year-round plant care. The tent combines thicker canvas, a fully reflective lining, and robust structural components so lights, ventilation, and support equipment perform predictably inside a confined footprint. Included components and thoughtful access points simplify setup and routine maintenance.

How does the P336 PRO prevent light leaks and improve light efficiency?

The tent uses a layered fabric system to stop stray light and maximize usable reflected light inside the chamber. A durable 2000D Oxford outer canvas is paired with plant-safe PE and a 100% Mylar reflective lining to redirect light toward plants rather than letting it escape.

• Three-layer material: 2000D Oxford, PE lining, and 100% reflective Mylar.
• Black-backed zipper section and interior lining to eliminate gap glow.
• Sealed seams and precision-cut entry points to minimize light seepage.

What structural features make this tent durable and stable?

VIVOSUN designed the P336 PRO with thick steel poles and optional high-CFM reinforcements so the frame resists flexing under heavy equipment. The φ22mm steel pole system and included support bars provide a solid anchor for lights, filters, and trellis attachments.

• 1" (φ22mm) steel poles for a robust frame and long-term durability.
• Three hanging bars included; supports additional bars for heavier loads.
• High-CFM support kit reduces sway from strong fans and secures trellis netting.

How does the tent simplify access, observation, and equipment routing?

The P336 PRO balances easy monitoring with maintenance-friendly access. A larger observation window lets you check plants without entering, the SBS zipper and removable door speed daily tasks, and dedicated ports and pockets keep cords and controllers tidy.

• Oversized observation window for quick visual checks without disturbing the microclimate.
• Smooth, secure SBS zipper and a removable door that attaches with hook-and-loop fasteners.
• Multiple cable-management slots, ventilation openings, and an external storage pocket for tools and controllers.

What equipment and accessories come with the tent, and what can be added?

The package ships with the essential hardware to get started: the tent shell, multiple hanging bars, support poles, and a floor tray. You can pair it with extra hanging bars, a ventilation fan, carbon filter, grow lights, and trellis netting; the PRO’s reinforced design supports heavier setups.

• Included: 36"x36"x72" tent, three hanging bars, four supporting poles, and a floor tray.
• Compatible with VIVOSUN fans, filters, lights, and additional support bars.
• High-CFM kit (included on PRO models except P224 & P276) stabilizes high-power configurations.

Who is this for? The VIVOSUN P336 PRO is aimed at indoor gardeners who need a compact footprint with commercial-grade components: hobby growers, apartment cultivators, and small research or propagation setups. It suits anyone who prioritizes a light-tight chamber, sturdy hardware for heavier lights and fans, and convenient, organized access for frequent monitoring and maintenance.
