Customizing Crop Foliage Color With LEDs: Ornamental Crops
Do you find that your purple fountain grass (Pennisetum setaceum ‘Rubrum’) crop is often green to light purple? What if we told you there is a quick solution to enhance and darken the foliage of purple fountain grass or other floriculture crops? In this second article of a four-part series highlighting the multiple uses of high-intensity light-emitting diodes (LEDs), we will discuss our research methodology and findings for enhancing the foliage color of ornamental crops with end-of-production (EOP) supplemental lighting (SL) in the greenhouse. Many ornamental crops that greenhouse and nursery growers produce vary in size, shape and color. These variables are often influenced by the growing environment. For example, leaf color (intensity, distribution or both) of ornamental crops such as purple fountain grass is a key component that often influences the consumer’s perception and ultimately an impulse purchase. The red or purple pigmentation of purple fountain grass leaves is […]

Technology Provides Solutions For Growing In Drought
In April, California Gov. Jerry Brown directed the State Water Resources Control Board to institute reductions in cities and towns across the state with the goal of reducing water usage by 25 percent. The announcement comes following the lowest snowpack ever recorded in the High Sierra. It was the first time in state history that action was taken to implement mandatory water restrictions. In May, the farmers in California’s Sacramento-San Joaquin River Delta agreed to reduce their water use by 25 percent in exchange for assurance that they will not face further curtailment during the June to September growing season. Their proposal was approved by the State Water Resources Control Board. Growers who participate in the program could opt to either reduce water diversions under their riparian rights by 25 percent, or fallow 25 percent of their land. Given these conditions, growers and retailers are in need of methods and […]
