The folks at BeerAdvocate note that while hydroponic growing techniques have been around since the early 17th century, growing hops in a mineral-rich nutrient solution is a recent endeavor, one they think will impact the beer indus- try, especially the craft beer brewers. “In the world of beer, one ingredient reigns supreme,” they report, “and that’s hops.” Getting them fresh and frequently from the field has been problematic, but the harvesting of hydroponic hops, grown under species-specific horticulture techniques, can be done in perpetual production according to HydroHop Farms in Colorado. “We have designed and developed methodology to over- come the single hop harvest per annum in field-grown condi- tions. Our Hoponics research model of perpetual production allows the ability to grow three to five crop cycles per year.” HydroHop harvests several varieties for wet-hop brewers using fresh product, hops that have been harvested less than 24 hours before. One brewer lauded the indoor efforts, noting the fresh hops were sticky and smelled great with no leaf burn found on outdoor-grown hops. Colorado State University (CSU) horticulture profes- sor Dr. Bill Bauerele leads that university’s research program focused on controlled environment hydroponic hop production. “January 2016 was our first crop. Now we’re doing five to six crops a year,” he says. Housed in a 40x80-foot greenhouse, Bauerele has some 3,200 square feet of growing space to experiment with an initial six or seven species of the 130 cultivars that are currently commercially available. “There’s some funding for hops breeding, but USDA has no federal grant monies for hops production, and at one point in our set-up, we ran out of money. As an army of one, we moved forward slowly and after a year and a half, have built a nice system with environmentally controlled watering and individual plant nutrient injections.” As an open-field farmer before becoming a researcher, Bauerele says, “People don’t realize how much work is involved here. Hops are a physically demanding plant and I’ve never worked this hard in my life.” grow cycle 103
