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 […]

5 New Heating Options For The Greenhouse
Five heating systems manufacturers share their latest and greatest products. Tubing And Aluminum Heat Pipes (BioTherm) From Megatube and MicroClimate tubing to DuoFin and StarFin aluminum heat pipe, BioTherm is dedicated to providing heat solutions that can withstand the toughest greenhouse environments. The MegaTube and MicroClimate tubing options are easy to install and ideal for bench or floor heating. The tubing has a conductive heating surface that allows for maximum root-zone heating. The DuoFin and StarFin aluminum pipe options are great for perimeter heating and melting snow trapped in the greenhouse gutter. It can also be useful for bench heating. Both pipe options provide gentle, radiant heat for plants and don’t require welding. TrueLeaf.net Infinite Energy 2 Condensing Boiler (Delta T Solutions) With up to 98 percent efficiency, the IE2 condensing boiler boasts a stainless steel heat exchanger with larger waterways to ensure maximum heat transfer. The product’s design ensures flexibility while […]

Aquatrols Renews Cooperative Research And Development Agreement With USDA
Aquatrols Corporation recently announced a new Cooperative Research and Development Agreement (CRADA) with Dr. Matt Madsen and the USDA Agricultural Research Service. The objective of the new CRADA is to further refine and evaluate surfactant seed coating technologies for use in wildfire rehabilitation, turf and pasture grasses, restoration species and other horticultural and agricultural systems. The three-year agreement renews a CRADA that Aquatrols first signed with the ARS in 2012. The original partnership has resulted in promising field and greenhouse trials, pending patents and initial steps toward commercialization of the surfactant seed coating technology. “We are very encouraged by the work that Dr. Madsen and his team have put together over the past three years,” says Aquatrols’ President and CEO Tracy Jarman. “This innovative technology has shown incredible potential with wide-ranging impacts in multiple industries. Aquatrols’ stated mission is to change the way the world grows and this technology has the […]
