I ve tortured myself for a month or more about how i m going to keep the veg in my new tunnel watered from november to may when there s no water on the all.
Polytunnel gutters are expensive to buy but this idea does exactly the same but at a bargain price.
Make sure that you have a drop of an inch or two at the end where the water is going to go so that the guttering can be lined up with it.
Or if you don t have a timber side rail and your polythene is trenched or fixed to a base rail we supply an extruded aluminium backing profile.
To ensure rainwater runs directly into the gutter a series of timber battens we used 19mm x 38mm pressure treated battens may be required to close off any gaps between the guttering and the side rail.
It can be fitted to a timber side rail on your new or existing polytunnel.
