Recycled Materials Greenhouse: Look for salvaged windows, doors, or even plastic bottles to use as the walls of your greenhouse. This not only keeps costs down but also reduces waste.  Below is a video on a greenhouse made from old recycled bottles.  The bottles worked marvelously to provide additional insulation by trapping air in between the walls of the greenhouse.
