USA, Idaho: 170° Fahrenheit Geothermal Waters Help Grow Produce at Hydroponic Farm

Laura Lee Farms: Growing hydroponic lettuce via renewable energy (AT&T)

White Arrow Ranch in Bliss, Idaho has hot springs that produce 1.5 million gallons of 170° Fahrenheit water daily—perfect for geothermally heating a greenhouse.

Technology is king at Laura Lee Farms. Geothermal energy heats the greenhouse. During the 50 days that it takes each seed to grow into harvestable food, sensors monitor temperature, humidity, and sunlight, keeping conditions ideal for plant growth and pest control. A computer monitors total dissolved salt in the feed water and injects more salt as necessary.
