The Liskey Farms, Inc. greenhouses, located about 10 miles south of Klamath Falls, Oregon, are back in operation. The main greenhouses, originally built in 1978 to raise trees for reforestation, were idle in the late 1980's. In 1990 they were cleaned up and put back into operation growing bedding plants and perennials this time, with the first crop sold in May of 1991. The operation utilizes six geothermal wells to heat five greenhouses, with the waste heat being used to maintain 37 shallow tropical fish ponds
