The Gorilla Grow Tent Pro 3x3 is a heavy-duty 9 sq ft indoor grow tent with 1680D canvas, a 19mm steel frame, and a patented height-adjustable design that extends up to 8'11" with the 2 ft extension kit.
Built for balanced small-footprint indoor grows that still need commercial-grade light-tightness and room to run a dialled-in single LED with full ventilation.
The Gorilla Grow Tent Pro 3x3 is a professional-grade 3x3 grow tent engineered for growers who want a balanced square footprint that fits in a spare room, garage corner, or dedicated indoor garden. Its 36" x 36" interior floor supports a centered LED with even canopy coverage, while the patented height-adjustable frame lets you grow up to 8'11" with the 2 ft extension kit sold separately.
Roughly 3x the density of standard 600D tents. Blocks 100% of exterior light and resists tears from daily use.
Rigid steel frame rated for a 300 lb hanging load so LEDs, carbon filters, inline fans, and ducting mount without flex.
Diffuses 95% of light back onto the canopy for even PAR distribution across the full 9 sq ft floor.
Inverted-U front door with double-cinching cuffs seals every seam against light leaks.
Patented telescoping design extends up to 7'11" with a 1 ft kit or 8'11" with the 2 ft kit.
Six 11" double-cinching ducting ports plus two 3" electrical ports keep every cable and duct managed.
