Tunnel cloches

I have plastic designed for tunnels and have used the same sheets for four years now - tatty and dirty, but still in one piece. I use rebar as supports because we had a load left after building.
Clay soil here too which can get too dry inside the tunnel so I have to remember to water. I use it to extend the season for beetroot, lettuces, parsley, and will direct sow radish later this month and lettuces in Feb or March.
To be honest, the spring side is much less successful than extending the autumn.
