Dennis and his wife, Gaylo, built their first greenhouse in 1997 and started farming alfalfa. When the price of water became too expensive they took a break from agriculture and leased their land to other farmers. When Dennis’ nephew became interested in greenhouses, the Elstons decided to try it on their own land and built their first greenhouse in 1997. Growing in greenhouses works well with Dennis’s off-the-farm job in construction, because the majority of their season takes place during the winter months. They plant in October and end in late May. The Elstons’ greenhouses are heated with propane when it is cold, and cooled with electric fans and cooling pads when it is warm.
