Grandio makes polycarbonate greenhouse kits for home growers, from the compact 6-foot-wide Element to the 12-foot-wide Summit. Every kit uses a powder-coated aluminum frame, twin-wall polycarbonate panels, roof vents and built-in rain gutters, and Grandio rates its greenhouses for up to 25 lb/ft² of snow and 76 mph winds when properly anchored. OffGrid Horizon is an authorized Grandio dealer.
