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 […]

Going The Distance For Quality

Dan & Jerry’s Greenhouses, an operation in Monticello, Minn., uses about 10 DosaCart fertilizer injectors from Dosatron within its greenhouse walls for production purposes. But Dan & Jerry’s actually owns about 220 Dosacarts. So what does it do with the others? It distributes the majority of them to its retail customers to keep up with fertilizing once product is out of Dan & Jerry’s hands. “We wanted our customers to feed the product at the garden center level,” says Jerry Quaal, co-owner and CFO of Dan & Jerry’s. “We saw what was happening at the chain store level. So we distributed the DosaCarts and said we want the trees, shrubs, annuals and perennials you’re getting from us fed once a week.” Dan & Jerry’s distributes its DosaCarts to retailers around the middle of April, and its customers use the fertilizer injectors through the end of June. “We’re doing this with […]

If At First You Don’t Succeed …

All Sam Martin wanted was to lessen his fuel costs, and he’s finally on the right path for his operation now that he’s burning coal to heat his greenhouses. But Martin’s journey to the right fuel source had its twists and turns. Lessons were learned, Martin got an extensive education in a variety of energy sources and others can use his experience as a reminder of what to do when exploring non-fossil fuels–and what not to do. Martin’s journey is unique because he has employed three different alternative energy systems–wood, corn and coal–in response to a recent rise in propane prices. Martin is heating four greenhouses that span about 20,000 square feet, and he’s using those greenhouses to grow vegetables for his business, Earth n’ Eats, in Chambersburg, Pa. The first alternative source Martin gave a try was wood. He has a friend who owns a sawmill, so slab wood […]

Double Harvest Provides Lifeline In Haiti

While ports have been jammed as international aid flows into Haiti, the Double Harvest Christian mission the Van Wingerden family founded in 1981 that is only eight miles from Port-au-Prince has immediately begun providing food, water, shelter and medical care for thousands devastated by last week’s earthquake. On Sunday, Abe Van Wingerden of Metrolina Greenhouses in Huntersville, N.C., provided this update on the relief efforts: – The Double Harvest team fed more than 3,000 people during the day Saturday in a kitchen/cafeteria that is set up to feed only 300. The tilapia farm has been a miracle as they await additional supplies. One fish can feed three people and they have more than 40,000 fish in the tilapia farm ready to eat, which was just built and finished in the last few months. – The Double Harvest team also gave out rice, eggs and fish to the five surrounding villages as hunger […]

Hanna Introduces HI 5000 Mini Fertigator

Hanna Instruments recently unveiled its latest product, the HI 5000 Mini Fertigator, which is an all-in-one, ready-to-use control system. The Mini Fertigator is compact and versatile, bringing precision nutrient and acid control to professional growers. It’s easy to install and comes completely pre-assembled. To install the unit, growers simply attach two pipes and plug in the power cord. No wiring or assembly is required. To inject nutrients, the Mini Fertigator uses a venturi, so there are no high-maintenance peristaltic pumps to worry about. Hanna’s included Blackstone pump can handle full-strength acid, so there is no need to risk an accident with dilution. Hanna’s flat-tipped probes are also highly resistant to fouling and clogging. Additionally, an automated dosing feature allows growers to optimize growth without spending half the time measuring, mixing and dosing. The Mini Fertigator allows the grower to set precision dosing during vegetative stages, maximizing harvest and profit. For […]

Irrigation Technology Reduces Waste Water

Forsta Filters has developed technology for reducing backwash waste water by as much as 75 percent. The company’s technology is called Green-Clean. Without interrupting system flow during backwash, Green-Clean technology utilizes smaller flush valves to minimize the volume of water required to remove buildup on a filter element. Using internal vacuum nozzles, the new Green-Clean system scans and removes debris from the filter in 15 seconds or less. This combination of short duration and small flush valve make the Green-Clean backwash cycle efficient. Forsta Filters offers a full line of self-cleaning water filters (1- to 36-inch flange size) with screen elements ranging from 5 to 4,000 micron. Integrating the Green-Clean technology in all products maximizes efficiency and reduces waste water and energy costs. Filters are constructed from all stainless steel and designed to provide a long-term solution to a wide range of industrial and municipal applications. For more information on […]
