“Going solar” doesn’t have to cost you an arm and a leg … nor does it necessarily mean a big investment of time and materials. In fact, you can complete the small-scale sun energy project pictured here in only a few minutes–using a handful of common household items–for as little as 15¢. And, once the device is assembled, the efficient little window greenhouse can be employed to start early garden seedlings or to raise greens and radishes through the winter.

Supplies and Construction

The first step in constructing the cardboard conservatory is to gather the necessary materials … all of which can probably be found right in your own home. If you have a closet or attic full of empty cardboard boxes, choose one that measures about 12″ X 12″ X 16″. (Folks who don’t have a ready supply of containers on hand can usually pick up cartons–for free–at large supermarkets.)
