Start Your Seedlings in Grow Tunnels

Give your seedlings the environment they need to grow with our unique range of grow tunnels. We supply materials to protect from insects, birds, wind or heavy rain from damaging your small crops. Choose between a fleece, micromesh, net or polythene cover options below. They are large enough to stand on their own on top of raised beds, patio planters or directly in your garden patch. Our grow tunnels are designed to sit above your row of veg, and stay put with secured ground pegs.

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.
