Today I was stumbling through Stumble Upon and happened to come across a great tutorial on building a $50 greenhouse! What is especially cool is that the author of the blog (The Door Garden) who wrote the tutorial is also a Tennessean (Cookeville). The greenhouse he built is a hoop house made from PVC and has about 165 square feet of space. This looks like a very economical project that home gardeners could definitely benefit from building. Go say “Hi!” to David and his $50 Greenhouse.
