Grow More greenhouses feature a heavy-duty tubular aluminum frame, superior 10mm triple wall polycarbonate panels, commercial grade hinged doors (1 Dutch door standard on all models), a built-in gutter system, and plenty of roof vents for maximum air circulation. Combine that with the Fast Click system that drastically reduces assembly time and a price hundreds less than any similarly equipped greenhouse, and you have a package that is hard to beat!
Enjoy the light diffusion and beauty that polycarbonate affords without the fear of breakage and drastic temperature changes experienced in glass greenhouses. The beautiful black painted aluminum frame on the Grow More greenhouses will blend in well in any location. Grow More greenhouses are rated for winds up to 70 mph and snow loads up to 25 lbs. per square foot.

90" x 13" x 12", 104" x 13" x 10", 95" x 13" x 9", 56" x 41" x 4", and 60" x 41" x 4" (x2)
