Amish Environmental Controls

By |

Amish growers operate without the luxury of electricity, but they could use a signal when their greenhouses are too hot or cold for their liking.

R&K Greenhouses, located in Fredericksburg, Ohio, has a unique environmental controls thermometer that’s battery operated and sounds a horn when the temperature is too hot or cold for the grower’s liking.

“We monitor greenhouse temperatures with battery-operated cordless indoor/outdoor thermometers and battery-operated alarms,” says Robert Hershberger, R&K Flowers.

Additionally, R&K moderates greenhouse temperatures with shutters on air thermostats and rollup sidewalls. R&K’s greenhouse space is just 6,720 square feet, but it also has four fans for cooling that turn because compressed air moves them.
