This fall we built the hemlock frame and my boys and I installed the hoops. We've built it across from the barn where it will have protection from wind by being below the riding ring and surrounded by trees which are at a distance that they won't obscure light. Friends helped me build the north plywood wall with doors, installing the channel lock and building the south doors. So much work.
The boys enjoyed swinging between the hoops and they said they had a blast installing a ton of lag screws with me.
This weekend two friends came to help. It was time to install the plastic. Saturday was the installation of the doors, the inflation kit, additional bracing and other little odd jobs that seem to take forever. Sunday was crunch day. The strong winds cleared through Saturday night leaving Sunday morning calm and clear.
We placed cardboard on the ground and then unrolled the plastic on one side. It was one full sheet of plastic which the instructions said to cut up the middle and then lay double layered over the greenhouse frame. Nope. No way was I going to cut anything. We grabbed the mid-line and started pulling it over. Thank goodness there were three of us. That was incredibly difficult. After a ton of work in pulling it over we aligned it straight and what do you know that's when the wind came up.
Immediately I had one person hold onto the plastic on the windward side and the other two of us wire locked one side. What a race! After securing that side we did the other one pulling with all our might to get the plastic as tight as possible.
Then we secured the north end. As you can see from pictures it's not a little greenhouse the peak is over 12 feet high. Using ladders on uneven ground, pulling plastic with one hand and holding on with the other was... quite a feat.
The hardest end was the south facing. We secured the bottom and then stretched and aligned the plastic up over the last hoop and under the other plastic. We wanted to only use one layer of wire lock to hold the main plastic and the end. This meant 2 people outside with one pulling the plastic of the main sheet tight and the other installing the wire lock while I was inside pulling like a mad woman to tighten and align the end plastic. Finally once that was secured we wire locked around the south doors and cut away the excess plastic. We were exhausted but thrilled it was on.
After catching our breath we then cut holes and installed the inflation kit hose. At first it didn't seem to be doing anything and we actually started wondering if we had stretched it too tight. Nope, in less than five minutes the plastic layers had separated and stretched taunt as a drum. I double checked all the wire lock and looked for any holes. Everything was great.
There is still a ton of work to do with it including building a drain outside, installing more support for winter and wind, insulating the plywood, trim work and of course getting the ground ready for planting.
Wow. I have a greenhouse!
