Walk-In Polytunnel Greenhouse with Galvanised Steel Frame and Roll-Up Windows 3.81 x 2.92 x 1.97m Green

  • Extend your growing season confidently - the fully enclosed UV-resistant PE cover maintains warmth and high humidity, making this polytunnel ideal for vegetables, herbs, tropical plants, and more across UK gardens.
  • Built to last with a heavy-duty galvanised steel frame that resists rust, corrosion, chipping, and peeling, supported by two extra reinforcing rods for added rigidity and long-term stability.
  • Stay cool and in control - a large roll-up ventilation window on each side of the tunnel provides effective cross ventilation on hot days, helping to regulate temperature and prevent overheating.
  • Walk in with ease thanks to the hinged door design, giving you comfortable, upright access to tend to your plants without the back strain of crouching into a traditional cold frame or cloche.
  • Lightweight and portable enough to reposition around your garden, patio, or allotment as your growing needs change throughout the seasons.
  • Overall dimensions: 3.81L x 2.92W x 1.97H m | Door size: 84W x 184H cm | Window size: 140L x 33H cm | Note: Not suitable for severe weather conditions

Extend your growing season and keep your plants thriving all year round with this large walk-in polytunnel greenhouse. The fully enclosed UV-resistant PE cover maintains high humidity and protects vegetables, flowers, and herbs from light rain and pests, while roll-up windows on each side ensure excellent cross ventilation on warmer days. Assembly is required.

Features:
  • Galvanised steel frame offers a robust, corrosion-resistant structure that won't rust, chip, or peel, giving your polytunnel lasting stability season after season.
  • UV-resistant, fully enclosed PE cover retains warmth and humidity - ideal for growing tropical plants, vegetables, and herbs even in cooler UK climates.
  • Two large roll-up windows, one on each side, allow effective cross ventilation on hot days and help drain excess water to reduce pressure on the frame.
  • Hinged door provides easy walk-in access, making watering, pruning, and harvesting far more comfortable than with smaller cold frames or cloches.
  • Two additional supporting rods reinforce the tunnel structure, improving overall rigidity and making the greenhouse more resistant to light wind.
