J & K Growers are located adjacent to the New Mexico State University (NMSU) campus in Las Cruces. They use geothermal energy to heat 1.6 acres of 18 polycovered greenhouses and cold frames. At first the owners, Kerry and John Krumrine, grew all potted plants and bedding crops on the ground to limit costs, especially with the use of in-ground heat. However, later they decided to put the crops on benches and further, from the buried heating source to increase air circulation, lower soil temperature and thus, decrease disease and pest problems
