18 Amazing DIY Greenhouse Ideas

There are those of us who could spend an entire afternoon daydreaming about cold frames and greenhouses. Regardless of whether you are looking for something simple and easy to complete or want to undergo a massive project, we have searched far and wide to produce a list of amazing DIY greenhouse ideas.

Each of these products is an end result of the love and passion that went into creating them. We have put together a list containing straw bale as the building material (which needs no tools or equipment to complete), old bottles, tree branches, windows, painted jugs, passive heating elements, and even a trampoline.

This idea is very simple to complete. By using straw bales, the heat will be held by walls that do not require any tools to complete. Finish the frame by simply using plastic or windows. In order to provide growing space, the first design slopes toward the south with tires. Check out the tutorial here.

Combining this hoop house design with straw bales was a great idea. Fencing material consisting of heavy gauged galvanized welded wire constructs the livestock panels. Because of the easy ability to remove the plastic cover, gourds, beans, and other summer plants are able to grow. This tutorial shows how easy this design is to build.

By simply pulling the two pieces of an old trampoline frame apart, you have the two archways needed to support your hoop house. Plastic jugs have been spray-painted black and filled with water. Throughout the day the water will heat up. At night, they provide extra warmth throughout the hoop house. You can find instructions for the project here.
