4 x 3m Walk-In Tunnel Polytunnel Greenhouse with Dual-Layer Door Six Roll-Up Windows and Galvanised Steel Frame White

  • Rated to withstand Beaufort 5-6 winds when fully secured, this polytunnel delivers real stability in exposed gardens and coastal locations - guy ropes and ground stakes are included in the box.
  • A dual-layer doorway gives you full climate control - switch between the heat-retaining PE zip door and the insect-screened mesh door depending on the weather, without leaving the entrance wide open.
  • Six roll-up side windows make it easy to manage airflow and temperature inside the tunnel, helping you create the ideal growing conditions for seedlings, vegetables, or tender plants.
  • The reinforced galvanised steel frame with V-shaped side bracing, corner post reinforcement, and a tensioned roof wire keeps the structure rigid and the 140 GSM PE cover drum-tight over time.
  • At 4 x 3m with 2m of standing headroom, there is space to move freely between rows, and the four-bay layout makes organising your growing area straightforward - perfect for most standard UK gardens.
  • Overall dimensions: 396L x 300W x 200H cm | Outer PE door: 174W x 155H cm | Inner mesh door: 153W x 185H cm | Side windows: 47W x 40H cm | Windproof rating: Beaufort Level 5-6 | Assembly: 3-4 people recommended

Transform your garden into a productive growing space with this generously sized 4 x 3m walk-in polytunnel greenhouse in white. Built around a reinforced galvanised steel frame with V-shaped side bracing, it offers comfortable standing headroom and enough room to grow a wide variety of crops, flowers, and seedlings throughout the season. Rated to withstand Beaufort 5-6 winds when fully secured, it suits exposed gardens and breezy coastal locations alike. Assembly requires 3-4 people.

Features:
  • Wind-rated stability gives you peace of mind - secured with the included guy ropes and ground stakes, the frame is rated to withstand Beaufort 5-6 winds, making it suitable for exposed gardens and coastal spots.
  • Dual-layer doorway lets you choose your climate - a PE zip door (174 x 155cm) retains warmth, while a taller mesh zip door (153 x 185cm) allows insect-screened ventilation without leaving the entrance exposed.
  • Six roll-up side windows provide flexible airflow control, letting you regulate temperature and humidity inside the tunnel to suit whatever you're growing.
  • Integrated bracing system including V-shaped side supports, reinforced corner posts, and a tensioned roof wire reduces flex, keeps the 140 GSM PE cover taut, and helps the four-bay frame hold its shape season after season.
  • Garden-ready from the box - ground stakes, guy ropes, a steel tension wire, 10 plant labels, and a pair of gloves are all included so you can get started straight away.
