Greenhouse

The greenhouse is a temperature-controlled structure which is used for starting seedlings, teaching and growth of warm-weather plants during the hot months. There is a water hydrant available for connecting hoses.

Heating
For starting seedlings in the colder margins of the season, propane based heat can be used. There is a dial that allows th temperature to be set. If the sensor detects that the temperature has fallen below what the dial is set to, the heater will ignite and proceed to heat the structure up to the desired temperature. It is not really feasible to begin production in the greenhouse before mid to late March and even then the heater should not be set on a high temperature (above 50-60 degrees F). Heat mats and tents may be used to enhance the local temperature around a flat for germinating seedlings and keeping roots warm.

Cooling
There is a ventilation system comprised of two sets of louvers on the west side and a large exhaust fan on the east side. There is a dial which sets the maximum temperature which will be allowed before the fan comes on. If the dial temperature is exceeded, a louver will open and the fan will come on. If the temperature is greatly exceeded, both louvers will open and the fan will come on at a higher speed. This can rapidly bring down the temperature of the structure and is essential during the hottest months. In extreme cases, opening the door on the west side can enhance the amount of cool air being drawn into the structure as the exhaust fan removes warm air.
