Thanks Derek and Wardy, I'll probably use them for growing some early lettuces, herbs and small carrots. I'm also going to see if they will work for producing some early strawberries. The irrigation hose inside the ones I don't use for salads and strawbs will probably be put to use under my potatoes next year. And I might build a cold frame or melon house and use these (cut down) to make the lid. Thanks for the suggestions :D
