The Deer Hunter built our greenhouse back in 2011 and we're still loving it. It's so handy to have it in our backyard. Prior to having our own greenhouse I used one down the road a ways. It was nice to have somewhere to start my seedlings, but looking back it was a good thing when I wasn't able to use that one anymore and we had to bite the bullet and build our own.
He had already bought 13 pieces of 3/4 X 20 foot pvc pipe, four- 4 X 4 posts, seven sheets 1/2 inch osb, and a roll of six mil clear plastic (we bought the wrong plastic-read the rest of the post to see why).
He attached 11 of the pieces to the 2 sides. He added 2 pieces of pvc down the length of the piece that would make the hoop to add additional support.
He then framed in the ends securing them to the ground with 4 X 4 posts. He put a door in one end and a framed opening for an exhaust fan in the other. When he got to this point he decided to bring each end in two feet to make an over hang on each end which would help protect the wood framing.
After that-it was time for the plastic. We draped it over the hoops leaving about two feet extra on each side. He attached the plastic on each end with metal roofing screws-screwing it directly to the pvc.
With the help of the girls-and Ruby Sue-we buried the plastic on each side. After he built and installed the door, we had a greenhouse of our very own for a little less than two days work and 250 bucks.
In the following year we had a couple of hail storms that damaged the greenhouse plastic and a strong wind finished the plastic off. Turns out we didn't buy the right kind of plastic in the first place.
The Deer Hunter said we should look at having to recover the greenhouse as a learning experience and as a chance to change things we wished we'd done differently the first go around.
The second go around we bought plastic specifically made for greenhouses. Once the hail damaged the first type of plastic we used it began to give way at all the pressure points. After studying on the issue for a while The Deer Hunter came up with the idea of using foam pipe insulation to cover the pipe/wood areas that came in direct contact with the plastic. The pipe insulation will also help protect our spring seedlings as it seals off some of the air gaps too.
We've not had any other hiccups with our greenhouse and after 6 years of use I'm still loving it!
p.s. Yesterday I took Granny over to Pap's grave so we could put fresh flowers on it. It wasn't even raining at our house, but by the time we drove the short distance it was coming a down pour at the graveyard. We set in the car until it quit and as I was helping Granny walk to the grave Chitter said "Look-a rainbow!" The rainbow looked like it was right over Pap and Granny's house. I'd like to send a big THANK YOU out to each of you for letting me share Pap's death story and for sharing your comfort and wisdom with me.
