This Outsunny large walk-in polytunnel greenhouse is perfect for year-round gardening. It features a durable polyethylene covering with grid threading and a sturdy Galvanized Steel Tube frame. Our poly tunnels with a door are great for seeding or protecting your young plants from the cold. The walk-in design provides protective surroundings without the high cost of a purpose-built greenhouse. It's ideal for growing tropical plants, vegetables, fruits, and flowers. The fully closed UV protection PE cover maintains high humidity levels and allows nourishing sunlight to pass through. Extended edges (15 cm) should be buried in the soil to tighten the cover for stability. The galvanized steel frame is solid and rust-resistant. For added stability, 4 included wind ropes should be tightened and fixed to the ground with 4 ground stakes. The overall dimensions are 3.5L x 2W x 2H meters, with a door size of 107L x 197W cm. Please note: To prolong service life, strengthen the greenhouse yourself before bad weather (windy, rainy, snowy, haily etc.). Not suitable for severe weather conditions.
