Greenhouse build progress
It has been a while since we sharing an update on our greenhouse build progress. Not much was accomplished during the heat of the summer. Now that fall is here we have taken advantage of cool weather and got busy with this project. The structure is up, the end walls are built and all of the double wall plastic is up and secured. The blower motor that inflated the canopy is installed and operational.
What’s left to do to the greenhouse
What do we have left to do with this greenhouse? The side curtains on our greenhouse need to be installed. This Zimmerman High Tunnel kit has curtains that secure at the bottom and drop down from the top to vent excess heat. After the side curtains are up and operational, the door needs to be built, covered with plastic and installed.
Once the door is on we need to bury an electrical line pulled through conduit. It will provide the power to the for the inflated fan and the fan that will blow air for the heat sink. Once the power is run to the greenhouse we will work on the grow boxes and making the heat sink operational.
The grow boxes
We have all four of them built and pushed to one side of the greenhouse. They need to be placed, spaced out, leveled and secured in place with stakes. An application of preplant will applied to the soil inside the grow boxes. Then they need to be topped off with a mixture of sand and sawdust. After mixing in an application of weekly feed and preplant with the sand and sawdust the grow boxes will be ready.
The two grow boxes down the center of the greenhouse will have the a-frame structure built to allow vertical gardening. That can be built after the seedlings are in and in the warmth and comfort of an operational geothermal heat sink greenhouse.
What’s left for the heat sink
So far we don’t have any more greenhouse build progress to report on the heat sink portion of this project. But it’s on our list of things to accomplish. Once the greenhouse is buttoned up the heat sink is our next project. The pipes on the inlet side of the heat sink will be bundled together and cut at the same height above the ground. The fan that will move air through the heat sink will be mounted on top of the barrel that will be our manifold. That barrel will then be partially buried over heat sink pipes.
