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!

The beautiful black painted aluminum frame on the Grow More greenhouses will blend in well in any location.
