The Gorilla Grow Tent Pro 4x4 is the flagship 16 sq ft hobby grow tent: 1680D canvas, 19mm steel frame, and a patented height-adjustable design that extends up to 8'11" with the 2 ft extension kit.
Built for growers stepping up from a 3x3 or 2x4 into a full single-LED canopy with commercial-grade light-tightness and a 300 lb hanging load.
The Gorilla Grow Tent Pro 4x4 is a professional-grade 4x4 grow tent engineered for growers who want a 16 sq ft canopy that fits in a spare room, basement, or dedicated grow space. Its 48" x 48" interior floor supports a single 400-500W full-spectrum LED with full 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 16 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.
