Walk-In Polytunnel Greenhouse with Zipped Roll-Up Doors Mesh Windows and Steel Frame 300 x 300cm Green

  • Maximise your growing space - this 300 x 300cm walk-in polytunnel is ideal for smaller gardens, giving you a dedicated shelter for plants, vegetables, and seedlings without taking over the whole plot.
  • Stay in control of ventilation with zipped roll-up doors that fix open and mesh side windows that let fresh air circulate freely, helping to keep your plants healthy and prevent overheating.
  • The three-layer polyethylene cover features a reinforcement grid for extra strength and an anti-UV coating that allows 85% sunlight through, giving your plants the light they need while shielding them from harsh weather.
  • A robust arched steel frame resists sagging and holds its shape season after season, ensuring your polytunnel stays looking good and performing well even through the worst of the British weather.
  • Stays firmly grounded in all conditions - extended cover edges bury into the soil, and the included ground stakes and guy ropes secure the structure against winds rated up to Level 4 (below 17.5mph).
  • Overall dimensions: 300L x 300W x 200H cm | Door opening: 180W x 170H cm | Side window: 125W x 50H cm | Windproof: Level 4 (below 17.5mph) | Two-person assembly recommended
