>>217989I finally got the second layer on the tunnel today. It is 58F outside and 82F inside the tunnel. The pics show the air layer between the two pieces of plastic and some of the freeze damage the plants sustained last week. Hopefully, it won't go above 90F and stay above for any length of time. If it does, I'll need to install some automatic vents that open when it is too hot inside.
I could still see many flowers and fruit still on the plants, so there's hope yet this experiment will work.
Anyone else have tunnels, greenhouse, hotbed, or cold frame?
