The new owner of a private hot springs in south-central Idaho plans to use the 160-degree water to heat greenhouses as part of an aquaponics system to grow lettuce by recycling fish waste.
White Arrow Ranch owner Ron Miller tells The Times-News (http://bit.ly/1bKc0fO) that he hopes to be producing 43,000 heads of lettuce a month by Jan. 1 and employing eight to 14 people per acre.
Miller obtained the ranch in September after the winner of an auction in May bowed out.
The central feature is a shallow geyser that produces 1.3 million gallons of 160-degree water a day.
In aquaponics, fish waste is pumped from a tank into grow beds, where bacteria convert it into the nitrates plants need. Miller says he plans to use tilapia and largemouth bass.
