Beautifully designed to be strong, functional, and to have ample room for your plants, the RIGA V 9.6 x 17.1-Foot Greenhouse is the perfect greenhouse for any gardener. Constructed so that you can grow and protect your plants in any season, the greenhouse features polycarbonate glaze which affords extra protection for your plants. The main body is coated with 8 MM UV-coated twin wall polycarbonate while the front and back is glazed with 10 MM UV-coated twin polycarbonate for additional strength. The strongest greenhouse in its class, the frame profiles are permanently attached so they won't loosen over time. The greenhouse windows and doors are made to ensure optimal ventilation, and the sturdy Dutch barn door even has a key lock. Assembly is a weekend project for one or two people.
