THE Greenhouse Project is partnering with Schaus Vorhies of Fairfield to put together a small food production hoop house for local schools. The project is located at 1000 W. Stone Street in Fairfield.
Schaus Vorhies has a manufacturing business. They burn/sand blast the paint off of agriculture equipment. The temperature in their furnace hood can get to 1600 degrees. That heat is blasted through a conduit that travels through their plant, heating as it goes. The final stage of removal of the heat from the plant, is a bag house where the impurities are removed from the air and the air and heat travels up a stack (above the building) to exit.
This hoop (greenhouse) will be heated by the waste heat coming out the stack at the plant, so the production facility will be located adjacent to the bag house air purifier. Testing of soil and air shows that this will be an ideal location and we expect that production will begin this fall/winter.

- Construction Phase I continued
The bed for the greenhouse growing area is insulated down 6 feet deep (with 4 inches of pink insulation board) to preserve the heat for the plants.
The pex tube is installed 4 feet underground. It will carry the hot water out to the sand/soil to warm the earth.
We had volunteers from the Horticulture Club at Fairfield High School –THANKS!
Putting in the concrete foundation under the poles that will hold up the trusses for the Greenhouse.
30 Truck loads of Certified Organic topsoil was moved into the greenhouse growing space. Thanks to Dan Walker for his help with this.
Finishing the plastic work along the ridge vent.
Putting up the trusses for the greenhouse structure.
Thanks to Mark Burnham and the Schaus Vorhies folks!
We were given this 17,000 gallon tank for use as a boiler (heat sink) to reserve heat for use in the greenhouse on weekends when the Schaus Vorhies plant is shut down. It came from the Jefferson Co roads crew.
The project as of November 20, 2013
- Construction continues
The tank needed cleaning, inside and out.
Thanks to the Jefferson Co Road Crew for moving the tank into the SVK shop for cleaning and painting…
Stretching the double layer of plastic over the trusses….
David Alan Yoder from Fox River Produce was our builder for the greenhouse structure.
- We kept working out the details of the waste heating system throughout the frigid winter.
- We set up the new growing space in the greenhouse
- We put in 24-inch raised beds. There was room for 10 long rows.
- The master gardeners installed the water lines, too.
- Drip irrigation seems to be working.
Grinnell College volunteers cam and worked on insulation for the water heating system.
Steve Keller, Master Gardener, helped till and set up the new growing space in the greenhouse.
- The Jefferson County Master Gardeners came to plant March 1.
- Heating System is up and running! We are convinced that it won't get below 40 degrees in the facility, so we are planting traditional spring salad greens and sprouting peas.
