VOUNOT Polytunnel Greenhouse 4x3x2m Walk-In Steel Frame

This VOUNOT walk-in polytunnel gives you a generous 12 square metres of growing space, making it well suited to kitchen gardens, allotments, or larger back gardens where you want to extend the growing season. At four metres long, three metres wide, and two metres tall, there is plenty of headroom to tend to tall plants comfortably, and enough floor space to arrange raised beds, containers, or growing bags side by side.

The cover is made from high-density polyethylene with UV treatment and water-repellent properties, so it shields your plants from harsh weather while still letting through the light they need to thrive. The steel frame uses 19mm galvanised pipes, which helps resist rust through wet British winters, and the base tarpaulin can be buried into the ground to anchor the structure against wind.

Getting in and out is straightforward thanks to the roller door, and the eight side windows fitted with mosquito mesh allow you to regulate airflow and temperature on warmer days without letting in unwanted pests. The whole structure is designed to be assembled and taken down without specialist tools, which is handy if you want to move it between seasons or store it during periods you are not using it.
