Containerized Greenhouse At Towner Nursery
The State Forest Service Nursery at Towner, North Dakota began construction on a 30 by 96 foot greenhouse with a 12 by 30 foot attached headhouse in September, 1976. The frame of the greenhouse is inch galvanized pipe purchased from Weeber Manufacturing Company. The hoop stakes, which support the arches, were permanently set in the foundation. A two by six framework for the walls was attached to the hoop stakes by use of pipe clamps. Treated (Chemonite) plywood insulated with technifoam forms the remainder of the 40 inch sidewall. The greenhouse end opposite the headhouse was covered with tedlar fiberglass. We found it necessary to reinforce the purlins with corner braces where they attached to the end wall. Without the extra braces, high winds would push the wall in, causing the clamps to slip. We also put poles under the 48 inch fans for extra support.
