Do you have tons of plastic bottles lying around your house and excess backyard space? If so, you might want to look into building a plastic bottle greenhouse. The greenhouse idea was devised and brought to life by Blue Rock Station. For $5 (the electronic version is $4), you can buy instructions to build one yourself.
Make sure you have plenty of tires for the rammed earth foundation, at least 1000 2-liter plastic bottles, straw bale, and two 55 gallon rain barrels. A hefty load of starting materials for sure, but nothing compared to what you would need for a traditional greenhouse. And what better use is there for plastic bottles (besides energy-intensive recycling)?
Blue Rock Station’s greenhouse booklet discusses design creation, site prep and drainage, wind issues, orientation, insulation, and more.
