Should cloches have an air gap top prevent over heating. I use them, as I am on a south-facing slope and my garden is usually a month behind others in the same area since my soil is colder. I made mine in an "A" frame shape, as I had some "Polygal" sheets rescued from the tip. They are opaque, not clear. Would this affect the sunlight entry too much?
