Our new pop-up greenhouse, with shade cloth on! Its not quite as easy as they make it look on the box, but it is pretty easy - just like putting a tent together. I like to have fresh greens all winter and this is how I do it. I have two Juwel Cold Frames. I sprayed black paint on two 1-gallon bottles for each. Fill the bottles with water and put them at the back wall of the Cold Frame.
