Polytunnels
10 WEEK LEAD TIME ON POLYTUNNELS AT PRESENT
Increase Your Growing Season
Because a polytunnel encloses a larger volume of air than a greenhouse, a polytunnel stays warmer longer, providing a frost free environment for a greater proportion of the year. For an even longer growing season, bubble insulation can be used or the polytunnel can be heated.
Why buy a polytunnel?
A Polytunnel can give you a mediterranean or even a tropical climate right in your garden. Grow exotic fruits and vegetables, and enjoy traditional fruit and vegetables out of season. A polytunnel encloses a larger volume of air than a greenhouse which enables a polytunnel to stay warmer for longer, providing a frost free environment for a greater proportion of the year. Polytunnels can give up to 5 degrees of frost protection. Another big advantage is shelter from wind and rain – for your plants and for you!
For the same price as a small greenhouse you can buy a large polytunnel. Polytunnels are also a safer alternative to glass houses. The polythene cover lasts 7 to 8 years and replacement covers generally cost about 20% of the complete polytunnel i.e. less than 3% of the tunnel price per year.
It is not necessary to concrete in the ground tubes – the poly-tunnel is held down by the polythene, which is buried in the ground.

Trust Knowle Nets
Our heritage can be traced back to 1965 at Knowle Farm Bridport, Dorset - the home of net making since the 9th century.
This tradition of hand finishing continues to this day in our exceptional modern Bristol workshops where all netting and tubes are cut by hand to fit your exact sizing. Each order is carefully packaged with clear instructions for easy installation.
Knowle Nets structures have unique tapered ends to the top tubes, allowing all poles to be joined directly. A much stronger structure built to withstand years of work and weather, backed by our 10 year structural guarantee.
