DIY Mini Greenhouses

Lengthening the growing season so you can continue to grow your plants when the weather turns cold is done through the use of a greenhouse. However, when most people think of greenhouses, they think of large glass structures that very few can afford to build. Fortunately, this isn't the only type of greenhouse. There are plenty of smaller options you can build on your own. The following are a few DIY mini greenhouses that you can make right in the comfort of your own backyard:
 

  • The polytunnel greenhouse ' You'll want to begin by creating a base out of wood boards connected with metal corner braces. The number of PVC pipes you use depends on the dimensions of your garden plot, but pipes should be about 8-10' in length. Curve pipes from one side of the base to the other, and secure in place  Then, drape a clear plastic sheet over the pipes, stapling it to the base.
     
  • The PVC pipe greenhouse ' PVC pipes are obviously quite useful. In fact, you can build a small greenhouse that includes the base, walls and roof using only PVC pipes. Connect the pipes together using PVC joints and once the structure is complete, cover it with plastic sheeting and use duct or packaging tape to bind it together.
     
  • The picture frame greenhouse ' Instead of using PVC pipes, you can also use picture frames. This will result in a smaller greenhouse that can easily be moved from one location to another. You'll want to attach the frames (and only the frames) to one another by screwing them together. Once the entire structure is built, add the glass back into the frames. If you want to paint or decorate it in any way, make sure you do so before replacing the glass.
