Coverings And Films: A Few New Options

  Poly-Tex The new FieldPro high tunnel (pictured) has been designed with the specialty crop grower in mind. Durable roof poly and roll-up sides will provide an environment that extends the growing season, protects crops and increases yields and profits. It is available in three standard widths and two roof styles. Another recent introduction from Poly-Tex is the Expansion Mansion (below), a sturdy and versatile growing structure. It is easily expandable and can be upgraded with a variety of ventilation and mechanical system options. Its traditional arch design can be fitted with double poly film or polycarbonate sheeting. It can be constructed as a freestanding or gutter-connected greenhouse. Co-Ex Corporation Polisnake is a new style of multi-walled sheet that is minimal in weight, offers high-load resistance and excellent light transmission. Due to unique reflection and refraction characteristics of the Polisnake sheeting, light transmission does not decrease but actually intensifies. Each […]

When To Water

University of Georgia’s Marc van Iersel is focused on knowing when to water. For the last seven years he has been working with soil moisture sensors to improve irrigation and reduce leaching and runoff water– seeking total water-use efficiency. Simultaneously, colleagues at the University of Maryland and Carnegie Mellon University were developing equipment that could take soil moisture measurements and transmit them to a central computer. In addition, the University of Colorado team had been focused on technology that demanded real-time modeling of water use based on environmental conditions in the nursery. “We had basically several projects that have been going off independently for the last seven years, and now we’re combining all of our efforts to develop a system that will be commercially available,” van Iersel says. So what’s the key ingredient keeping these somewhat separate agendas together? A $5.16 million, five-year USDA Specialty Crops Research Initiative Sensor Networks […]

Virtual Grower Now Available En Espaňol

The USDA-ARS Virtual Grower program is now available in Spanish as Virtual Grower 2.5 en Español. It can be downloaded for free at VirtualGrower.net. The software program is a decision support tool for greenhouse growers and those interested in building a greenhouse. Users can build a virtual greenhouse in the comfort of their home or office with a variety of glazing materials, heating setups, fuel types, supplemental lighting and energy curtains. The program enables the user to schedule temperature set points throughout the year and predict heating costs for more than 230 sites within the United States. Different heating and scheduling scenarios can be predicted with a few inputs. The program can estimate fuel costs and plant growth for a production season or crop. Virtual Grower is continually being updated with information generated by the USDA-ARS and universities across the U.S. The Spanish version can be installed alongside the existing […]

Online Only: Costin Talks Carts

Greenhouse Grower caught up with Container Centralen (CC) President Sonny Costin, who shares his vision for a rented transported cart system in the United States, his take on the effectiveness of RFID in tracking carts and more. Are there a lot of carts purchases being made by growers right now? Cart usage and growth is very strong. Retailers strongly prefer delivery on carts over floor-loaded trailers. In addition, retailers want live plants delivered using sustainable packaging. Container Centralen’s cart system offers a nationwide sustainable packing system for the horticultural industry and this has reinforced growth in usage of CC carts. In addition, larger growers are buying in more and more product and want their inbound purchases to flow seamlessly into their businesses – this is another major source of growth for horticultural carts. Lost carts: How big a problem are they for U.S. growers? Anybody who uses carts has an […]

Minimizing Cart Loss

A driver recovering Container Centralen racks finds a person at the rear of a retail store loading Container Centralen equipment into a truck. That’s odd, the driver thinks, so he questions the person about the loading job. The driver quickly realizes this person is stealing carts and planning to deliver them to a scrap metal yard. Container Centralen files a police report with the information the driver provides, and the driver now qualifies for a $500 reward as an incentive of Container Centralen’s new Equipment Protection Program. Container Centralen wins because it maintains its equipment; the driver wins because he’s eligible for a fistful of cash; growers win because they’ll have a load of carts to use for their next shipments; and retailers win because they’ve helped their vendors keep costs down and prevented an act of theft on their property. “Cart and rack theft varies by region,” says Sonny […]

Neptune Pump Now Complies With Standards

Neptune Chemical Pump Company’s Polymaster polymer makedown systems now comply with UL778 and CSA C22.2 No. 108-01 standards. The Polymaster system dilutes, mixes and thoroughly activates emulsion, dispersion and solution polymers. Polymasters are available in a range of models to produce from 20 to 1200 gph (75 to 4500 lpm) of activated solution at concentrations from 0.1 percent to 2.0 percent. The motorized Gatlin distribution head allows the Polymaster to achieve a high degree of activation at all flow rates. The Gatlin distribution head hydraulically segments polymers into ultra-thin film platelets to maximize the polymer surface area exposed to dilution water, providing maximum activation. The Gatlin distribution head also ensures the degree of polymer activation is not affected by fluctuating water pressures or dilution water-ratio changes. Automatic units adjust polymer pump-flow rate by pacing the speed of the polymer pump to an external 4-20mA signal. Loss of dilution water causes […]
