A spacious, sturdy polytunnel for serious growing. This 3 x 4m walk-in polytunnel greenhouse gives you plenty of room to grow vegetables, tomatoes, herbs, flowers and seedlings, protected from cold, wind and light rain. A galvanised steel frame with slanted bracing, a reinforced grid PE cover and a proper hinged door make it a strong, practical choice for gardens and allotments.
Key Features:
✅ Spacious 3 x 4m Walk-In Design: At 400 x 295 x 200cm, there’s plenty of space to stand, work, and fit raised beds, grow bags and staging.
✅ Hinged Door for Easy Access: Unlike zip-up doors, the hinged door opens and closes easily for quick, convenient trips in and out with tools, trays and watering cans.
✅ 8 Roll-Up Mesh Windows: Plenty of ventilation keeps air circulating, helps control temperature and humidity, and reduces condensation. The insect mesh helps keep pests out.
✅ Reinforced 140gsm PE Cover: A built-in reinforcement grid helps prevent tears and damage, and the translucent cover lets sunlight through for healthy plant growth.
✅ Galvanised Steel Frame with Bracing: A rust-resistant galvanised steel frame with slanted bracing tubes gives a strong, stable structure built for outdoor use.
✅ Wind Resistant up to Level 5–6: Designed to withstand winds of up to 31mph when properly secured.
✅ 15cm Ground Skirt: The extended cover edges can be buried in the soil or weighed down for extra stability and to keep draughts out.
✅ Anchoring Kit Included: 4 ground stakes and 4 guy ropes help hold the polytunnel firmly in place.
✅ Extend Your Growing Season: Start seeds earlier in spring and keep harvesting later into autumn.
