Our Half-Dome Greenhouse: Not Pretty, But Practical


Tabatha and Shane head shotThe final modification we made to our garden in 2011 was to add a greenhouse.  The cold nights were harsh on the plants and managed to kill the green pepper, tomato, and cucumber plants we had.  The beets, cabbage, and broccoli were surviving, but we knew they needed protection from the cold.  About a week after I finished the project, we received our latest issue of GRIT that happened to have an article on a D.I.Y. greenhouse.  I had to laugh a little when I saw the great design in the magazine compared to my half dome version that I built.

  My boys and I made a trip to the local Home Depot to purchase some 1/2 inch PVC pipe (schedule 40), T-connectors, 6 mil heavy duty plastic, and some wide Gorilla Tape.  I wasn't exactly sure what shape to give the greenhouse, so I decided to just start building and adjust as necessary.  The structure naturally took a rounded shape from the beginning.  The PVC pipe was very easy to work with.

I added some short sections of PVC around the edge of the brick garden border.  I covered the tops of these pipes with some tape.  These sections of pipe will help to keep the plastic covering from rubbing against the bricks and tearing.

All I needed to do now was to add the plastic covering, or so I thought.  After I started adding the plastic, I realized that I had not accounted for a way to gain access to our garden after the greenhouse was finished.  At this point I was hoping that I would be able to just pick up the plastic along the center pole in the front and pull it up high enough to access the garden.  In the end, this actually worked!

You can find more pics on our Facebook page: www.facebook.com/stonehillgarden. Right after we put up the greenhouse, the weather warmed up a little. The kids have been a little more interested in helping with the garden, because they like to climb inside the greenhouse. We're hoping that this helps to improve how ofter we can harvest our veggies.

Some of my friends are using the same type, but in a tunnel shape. They can enter either end. Very functional.

Tabatha and Shane, what a great hoop house design. Simple, cheap, and effective to keep the container garden safe from the frosty weather. Involving the whole family will inspire everyone to eat more of what comes from the winter garden. With the warm weather that we are having here in Nebraska, it would have been a great year to have hoop covers over the garden beds. Have a great day under the hoop cover.
