Greenhouse Cooling, Ventilating & Shading
The improved Poly-Vent natural ventilation system from Poly-Tex is an alternative to rack-and-pinion vents and rollup curtain systems. The new frame has improved water drainage and is designed to be mounted to most greenhouse sidewalls without modification. Poly-Vent operates using only small blowers that can be thermostatically controlled. Single-stage allows growers to fully open or close off their ventilation while two-stage gives them the ability to select different temperatures at which the top and bottom will open or close. Combined with aluminum-wall housing, an aluminum shutter and a vinyl-coated wire guard, AL aluminum fans from American Coolair provide years of service. The aluminum blades of fans are bolted to a cast aluminum hub, which also serves as the fan pulley. Power is applied through V-belts directly to the propeller with the blade load concentrated directly over the fan bearings, eliminating overhung bearing load. It is available with single- or two-speed […]

Netafim’s More Sustainable Dripline
Netafim USA’s high performance Techline CV dripline is now manufactured with recycled materials, giving Netafim the opportunity to earn LEED credits on landscape installations. Techline CV is used in a broad range of applications to irrigate turf, trees, shrubs and bedding areas. The flexible tubing features two PSI check valves in each dripper for equalized application of water throughout the system (all drippers turn on and off at the same time). Check valves also prevent low emitter drainage with elevation changes up to 4 1/2 feet. Techline CV’s dripper design offers continuous self-flushing throughout the line, not just at the beginning or end or a cycle. Pressure compensation allows equal amounts of water to be delivered over a broad pressure range (14.7 to 70 PSI), and a physical root barrier protects the internal system from root intrusion without chemicals. Techline CV can be installed above ground or sub-surface, and it delivers water directly […]

Greenhouse Equipment: Improving Your Efficiencies
Dramm The new 350PL Screen-Aire updates Dramm’s popular nursery nozzle by reducing the weight and cost. Made from durable, lightweight POM plastic and stainless steel screens, the 350PL offers high flow with a soft, aerated pattern. Perfect for watering containers quickly, the aerated flow will not disturb soil or fertilizer in the container. The air-intake holes entrain air to soften the flow and add much-needed oxygen to the water for better plant growth. Orival The ORG series of automatic, self-cleaning, line pressure-powered water filters are available in sizes from 1.5- to 8-inch single units that can handle flow rates up to 1320 gpm. Units can be installed in parallel to handle larger flow rates. Fine screens are available down to 1500 mesh in a variety of constructions, including standard stainless steel mesh, multi-layer sintered stainless steel and wedgewire. Growing Systems New boomless monorail traveling irrigators are custom made for any […]

Counting On Carts
Keeping track of carts and making sure there is enough on hand for shipments when spring gets rolling is an issue for wholesale growers of all sizes, whether they serve large retailers or independent garden centers. Take Robin Waldrop Sr. of First Stage Greenhouses near South Bend, Ind., who serves garden centers within a 150-mile radius. He takes good care of his carts and hates to see them swapped out with old rusty ones in exchange on a return trip. “The problem I’ve run into geographically is other growers using the same type of cart as us,” he says. “It’s tough to ship new carts out and get old ones back, even though they are the same type. We have all our wholesale customers unload them while our drivers wait. It’s worth it for me to pay my drivers to wait rather than wondering where my carts are, or worse […]

Spectrum Receives 18th AE50 Award
Spectrum Technologies recently received its 18th AE50 Award from the American Society of Agricultural and Biological Engineers. The prestigious AE50 award represents the best and brightest products developed throughout the world for the agricultural, food and biological systems industries expected to save producers time, costs and labor while improving user safety. Recognizing the need for affordable weather recording in remote microclimates, Spectrum has developed the WatchDog 1000 Series Micro Stations as user-friendly devices to capture, process and store weather history throughout the growing season. These powerful recorders present current and historical weather data, degree-day calculations and plant disease alerts on location. Create your own station with multiple sensor options or purchase pre-packaged Plant Disease, Plant Growth, or Irrigation Micro Stations. Mike Dunning, weather products manager for Spectrum, explains that the WatchDog 1000 Series Micro Stations combine the inexpensive reliability of simple data loggers with pre-packaged sensors specific to a growers […]

New Dramm Filter Filters Finer Than Sand
VitroClean Green crushed glass filter media from DRAMMwater is manufactured from recycled, processed glass and is a direct replacement for silica sand and other materials in media filters. VitroClean offers you the safest, most reliable and cost effective way to upgrade your new or existing sand filter system. Designed to work in existing sand filter, VitroClean Glass Media will filter finer than sand with 20 percent less media required. Unlike sand, VitroClean media has a non-crystalline shape offering less density and more open space between grains to trap fine particulate. Because it is crushed glass, it does not degrade like sand, allowing for a greatly reduced need for replacement due to degradation of the media. Even though it is made from crushed glass, VitroClean media is safe to handle, with no jagged edges. DRAMMwater is a newly formed division of the Dramm Corporation. Focusing on water treatment for horticulture, DRAMMwater […]

Chlorine Dioxide In Horticulture: A Technology Review
Horticultural operations are facing increasing pressure to solve sanitation issues related to water treatment. Some of the pressure is external originating from government regulations and consumer preferences. Most of the pressure, however, is internal and includes better disease management, integrating capture of irrigation runoff with recycling opportunities, elimination of biofilm and algae control. The list of available water treatment technologies is a short one. When the unusual demands of horticultural production and post-production practices are considered, the list of technologies that offers effective solutions becomes even shorter. Chlorination, ultraviolet light, chlorine dioxide, ozone, copper and peroxide comprise the list most growers are considering. This article will present a technology review of chlorine dioxide and discuss its potential to solve sanitation issues in greenhouses and nurseries. Biofilm, Sanitation’s Epicenter Biofilm is a living complex of organic and inorganic components that becomes established on surfaces that are in regular contact with water. […]

Spectrum Receives Two AE50 Awards
Spectrum Technologies has been honored this year with two AE50 Awards from the American Society of Agricultural and Biological Engineers. A manufacturer of weather stations, data loggers and handheld measurement devices, Spectrum was recently recognized for its LightScout DLI 100 light meter. The light meter is a one-button operated meter that measures the light “falling” on your plants. It measures PAR light (photosynthetically active radiation) and, with a push of a button, the meter runs for 24 hours and calculates your daily light integral (DLI). The DLI 100 Meter is sold in sets of three so you can compare light measurements simultaneously at three locations. The prestigious AE50 award recognizes the top 50 innovative new products produced throughout the world for the agricultural, food and biological systems industries expected to save producers time, costs and labor while improving user safety.
