Is anyone here in to `cold frames,` which are a sort of do-it-yourself version of greenhouse? If so, how did you construct it, what materials did you use, and how effective is it compared to a bought greenhouse?

tom, how about using 4 Hay Bales and a Window Frame?

Another and even cheaper option is to build a simple, more or less "old-fashioned" cold frame yourself, using four rectangular bales of hay and an intact window frame. Arrange the hay bales so that they form a square with a space in the center of a size that can be covered by laying the window frame flat on top. The hay will provide insulation and the window frame will let in light. Just remember when it's sunny to prop the window open with a brick to provide adequate ventilation (so you don't "cook" your plants), and don't forget to water.

After a little while in the nourishing environs of the cold frame, your plants will be "all grown up" — ready to make it on their own out in the garden. :wink:
