Use these special PVC fittings to make almost anything: raised bed frames, cold frames, scrog screens, hoop houses, greenhouses, awnings, limited only by your imagination! And recycle yourself into another project later. These represent a revolution in building design and construction—inexpensive, amazingly versatile, and easy to use. Anyone can use these to make things to your exact specifications and save hundreds, even thousands of dollars. Designed for construction and not irrigation, better to not use for water.
