This polytunnel greenhouse is perfect for both new and experienced gardeners. It can accommodate a considerable number of plants, and is great for seeding and protecting your plants from the cold weather. The portable greenhouse is constructed from a hard-wearing green polyethylene covering with gridded reinforcements and a sturdy powder-coated steel frame for durability. The cover helps protect your plants and minimise damages from exterior. It is a great alternative to a traditional glass greenhouse. The walk-in greenhouse features a front door with double zippers, which can be rolled up, for easy entry as well as air ventilation. 8 windows (4 on each side) with roll-up covers are also perfect for cross ventilation on hot days. Assembly is really easy. This polytunnel greenhouse can be quickly fastened with the included rope. No special tool is required. Please note the roof of our greenhouse cannot withstand heavy snowfall or very strong wind.
