Nurturing Urban Gardens

An urban garden in St. Louis will be able to produce more fresh produce for its neighborhood this spring thanks to a new greenhouse it received from Nexus Corp. as part of a national contest. New Roots Urban Farm was chosen as the winning entry. The nonprofit was founded by four friends in 2004 to provide healthy, locally grown food for the impoverished neighborhood located between St. Louis Place and the city’s Old North neighborhoods. No grocery stores are available within walking distance to offer healthy food options. The consensus-based collective is dedicated to serving as a model for urban agriculture, food security and self sustainability. Last year, the farm harvested more than 3,000 pounds of fresh produce and distributed it through its farmers market, which accepts food stamps, and through food pantries, churches and community centers. With the new Cultivator Premier Kit Greenhouse from Nexus, the farm will be […]

September’s here, and heating season is just around the corner. It’s the perfect time to get out and make sure your heating system is ready for the next few months. A bit of routine maintenance will ensure your plants will have the warmth they need, when they need it. The National Greenhouse Manufacturers Association offers heating guidelines (you can download a copy at www.ngma.com/downloads.htm), including a 12-point preseason maintenance checklist. We spoke with a few experts in the field–Russell Zabel, general manager, Delta T Solutions; Gregory Gawne, vice president business development, Total Energy Group; and Chris Smith, marketing manager, L.B. White Co.–to get their input on some of the items on the NGMA list, as well as a few other helpful tips on how to get the most out of your fall heating maintenance: 1. Check equipment for physical damage. Check the sheet metal, fans and air movers, wiring, fuel piping […]

Money-Back Guarantees?

Maybe the old adage is true – they just don’t make things the way they used to. But a lot of times, they make them better. Greenhouse equipment, like transplanters, continue to grow in their flexibility and options, while innovations like heat retention curtains and plug tray fillers solve problems in new ways. It all sounds great, but who has the capital for it all? Return on investment is an elusive calculation with all the moving parts of a greenhouse, but how do suppliers suggest growers approach equipment purchases?  Why Automate? As owner of a greenhouse and (presumably) the highest paid staff member, your time is valuable. “A lot of growers don’t consider their time being worth enough, or don’t consider their time at all,” says David Steiner, vice president of the Blackmore Co. Whether it’s your own time or the time of employees, labor is a tricky equation for growers. […]

In Control

Wadsworth Control Systems’ STEP Up control has more functionality than the traditional STEP 50A control but costs less. STEP stands for Single Total Environmental Control, and in addition to loads of new features, the STEP Up has a new look, too. “We decided to update our classic line of STEP controls, and the newest member has a very different look,” says Gary Dean, president of Wadsworth Control Systems. The new device also uses a flat panel touch pad layout with a wheel to navigate, which is high tech yet simple, according to Wadsworth’s Vice President Patricia Dean. “This easy-to-use design appeals to both traditional STEP 50 and STEP 500 users who are accustomed to the easy turn knob, but it is also familiar to iPod users who click and select by turning a virtual wheel,” she says. To make room for the STEP Up control’s push button override switches, the […]

Essential Equipment

If you think about it, there has been a huge increase in tools and instruments available to greenhouse growers during the last couple of decades that vary from large instruments like greenhouse control computers, to more portable instruments that help with day-to-day monitoring of plant growth. This article outlines some of the portable instruments available today and advantages and disadvantages of each. In many cases, these instruments can save you money by avoiding production problems, reducing the amount of outside testing that needs to be done and helping in immediate problem solving. How many times would you like to know your pH and EC immediately to decide what to fertilize with at that moment? What is your plant temperature? Is your media temperature what you think it is? New instruments available today can answer these questions.  Infrared Thermometers Temperatures are rarely what we think they are! This is especially the […]
