  3. 6 x 3m Polytunnel Greenhouse with Dual-Layer Mesh Door 8 Windows and V-Brace Wind Reinforcement White

6 x 3m Polytunnel Greenhouse with Dual-Layer Mesh Door 8 Windows and V-Brace Wind Reinforcement White

  • Dual-layer door for all-season flexibility - the outer PE cover closes down for warmth and wind resistance whilst the inner mesh door keeps insects out during the day, giving you precise climate control from late winter through to autumn.
  • Level 5-6 wind resistance when fully anchored, thanks to V-shaped diagonal bracing, reinforced corner posts, and a roof-mounted steel wire rope that minimises frame movement even in blustery British conditions.
  • Eight adjustable roll-up mesh windows let you fine-tune airflow around your plants to manage humidity and heat build-up, preventing the wilting and disease that poorly ventilated polytunnels are prone to.
  • A 15cm ground skirt seals the base of the tunnel against cold draughts at soil level, working alongside the four guy ropes and ground stakes included in the box for a stable, draught-resistant setup.
  • Spacious 6 x 3m walk-in interior - tall enough to stand in at 196cm - gives you ample room for raised beds, shelving, and seedling trays, making it practical for serious kitchen gardeners and allotment growers alike.
  • Overall dimensions: 591L x 300W x 196H cm | Outer door opening: 174W x 165H cm | Side windows: 47W x 38H cm each | Windproof level: 5-6 (when fully anchored) | Assembly: 3-4 people recommended

Give your plants the space and protection they deserve with this generously sized 6 x 3m polytunnel greenhouse. Engineered for the unpredictable British climate, it features a reinforced galvanised steel frame with V-shaped diagonal bracing, a 140gsm PE mesh cover, and a dual-layer zippered door system that balances ventilation with insect and wind protection. Designed for 3-4 people to assemble, it arrives with everything you need to anchor it securely and get growing.

Features:
  • Dual-layer zippered door system combines a PE cover and an inner mesh door, letting you control ventilation and warmth independently - ideal for early spring when temperatures can swing dramatically.
  • Advanced wind reinforcement using V-shaped diagonal bracing, reinforced corner door posts, and a steel wire rope along the roof reduces frame movement and delivers wind resistance up to level 5-6 when properly anchored.
  • Eight roll-up mesh windows with tie straps provide adjustable airflow around the tunnel, helping you regulate humidity and temperature without exposing young plants to sudden cold draughts.
  • A 15cm extended ground skirt works in tandem with the included guy ropes and ground stakes to seal the base against soil-level draughts and improve overall stability in exposed garden positions.
  • Durable 140gsm PE mesh cover features PVC-coated polyester edging and heavy-duty No.8 zips at all stress points, ensuring the polytunnel stands up to repeated seasonal use without deterioration.
