New Equipment Woes

Does this font make me look fat? OK, don’t answer that. If you think you notice something different about Greenhouse Grower this month but can’t quite put your finger on it, you’re right. We have new fonts. It’s a mini-makeover, a grooming. The new fonts are just the visible part of a huge overhaul going on here at Meister Media Worldwide. Our editors, artists and production staff have switched page layout software, moving from Quark to InDesign. And it hasn’t been a completely painless process. There are new keystrokes and workflows to learn, but ultimately this move brings us into the 21st century. Even though we all knew that this switch would increase productivity and add a few tools that would make work easier, I think we all resisted, at least a little. Yes, new is good, but it also takes a while to get used to. Now I have a […]

Fueling Expansion

Generation X growers are ready for tomorrow’s challenges. Pictured from left are John Bonner, sister Jill Cain with husband Todd Cain. When we visited, they were growing Easter crops in new greenhouses.In less than 10 years, Eagle Creek Growers in Mantua, Ohio, has emerged as a model mid-sized operation with room to grow. The modern growing operation was founded in 1998 by Jill (Bonner) Cain about an hour’s drive southeast of Cleveland. She was fresh out of college, implementing a business plan she drafted for a course at Ohio University. Up until recently, Eagle Creek’s primary customer was Eagle Creek Garden Center, an upscale destination garden center she opened in nearby Bainbridge four years later. In 2003, her brother, John Bonner, and husband, Todd Cain, took over the wholesale operation while Jill focused most of her time on retail. Both John and Jill are third-generation entrepreneurs in our industry. Their grandfather, […]

Who’s Your Mr. Fix-It?

To be honest, greenhouses mystify me. I don’t know how all of you out there do it. So much can go wrong–disease and pests, nutrition–and that’s just problems with your plants. Your structures are a whole other story. There are so many things to worry about–not enough heat, too much heat, expensive heat, water logistics. And, of course, there are the more extreme worries–debilitating hurricanes, fires and snowstorms. Getting ahead and staying ahead of structures issues is a job in itself, forget about growing great plants. That’s why we were so impressed when we visited Eagle Creek’s greenhouses in Mantua, Ohio. Siblings John Bonner and Jill Cain gave us the grand tour of the facilities, but Gary Jansen, the facility’s maintenance magician and all-around Mr. Fix-It, really impressed us. The facility has switched its fuel source from petroleum-based products to wood-based products. And the mid-sized operation has two huge indoor pools […]

Under New Management

Last fall, the National Greenhouse Manufacturers Association (NGMA) contracted with Calabrese Management, an organizational management firm based in Harrisburg, Pa. After 10 years with its previous executive director, Melanie Hughes of Hughes & Stuart Marketing in Littleton, Colo., NGMA is sure to go through some changes. NGMA’s new executive director, Denise R. Calabrese, owner of Calabrese Management, says her firm’s goal is to work with the volunteer leadership to strengthen NGMA as an organization. “We will be working with the board of directors to analyze existing programs and ensure that the needs of the industry are met,” she says. Some of these more imminent improvements, she adds, will be in the organization’s communication structure–improving NGMA’s Web site and newsletter, and increasing electronic communications. On the educational side, NGMA’s meeting agendas will be strengthened to provide valuable information to the industry, Calabrese says. For instance, the annual meeting NGMA hosts each spring […]

NGMA: The Next Generation

Fifty years makes a huge difference in the evolution of greenhouse architecture. From lean-tos and quonsets to gutter-connected, retractable-roof structures, commercial greenhouses have gained much from advances in technology. With more modern greenhouses have come advancements in the “furniture” to fill them, also known as greenhouse equipment and supplies, as well as innovative plastic films, which have revolutionized greenhouse shapes and framing systems. The growth of commercial floriculture and greenhouse vegetables over the years has fueled demand for greenhouse technology, and new manufacturers have emerged, raising competition and quality standards. All of this innovation needed organization–enter the National Greenhouse Manufacturers Association (NGMA). Founded in 1958, NGMA represents 65 member companies–27 component, 14 structural and nine service. These include greenhouse manufacturers, equipment manufacturers and suppliers, as well as researchers, students, growers and other allied trades serving the international horticulture industry. Retrofitting Itself Today, NGMA is working to promote and defend greenhouse construction […]

Retrofitting Options

Retrofitting a greenhouse is all about spending money to save money. In many cases, increased energy efficiency may be the easiest way to see new technologies impact the bottom line. However, the benefit of improved crop performance should not be overlooked as a factor in the bottom line savings (or rather gains)–from faster turns and fewer chemicals to improved labor conditions and reduced disease potential. Though there are numerous components of a greenhouse where retrofitting may result in greater efficiency, this article will focus on those that influence temperature and light. Shade Netting For years, shade netting was available in black with the amount of shade determined by how tightly knit the fabric was woven. The purpose was primarily to reduce heat or light. Over the years, new colors have been introduced, including an aluminum covered fiber, in an effort to manage the light while reducing the heat. Frank Giglia, […]

Attacking Growers’ Diverse Challenges

No two greenhouses are alike. Each has its own set of differences, such as the crops, the climate, the production volume, the existing facilities and more. It is also true that no two greenhouse builders are exactly alike in their approaches to the challenges provided by the diversity of growers. "Most of the commercial growers we deal with have a little bit of glass and have a little bit of polyethylene, as well as some longer-term plastics covering," says Scott Thompson, executive vice president at X.S. Smith Inc., Washington, N.C. "They like to see a mixture, because at certain times of the year or in stages of their production cycle, those areas are constantly in operation. Our mission is to try to design and create systems that will accommodate their particular production needs for the crop they grow, as well as the region where they are producing that crop." Maintaining temperatures […]

A Dose Of Precision

Seeking to improve chemical drenching applications, Dramm Corporation has redesigned its popular Chemdose precision drenching system. The new Chemdose 2 system can be worn on the chest or mounted on a small cart for portability. The CD2 connects to the hose from your injector or sprayer (under 100 psi) and accurately measures the solution into even, selectable doses with the push of a button. Push another button and the Chemdose 2 will meter out those doses on a variable interval basis. Utilizing the CD2’s digital controls, growers may select the amount of the dose, change the interval between automatic doses, count the doses made, set a maximum number of doses limit and even lock out the controls. The previous units operated well but were limited by their tank size, power requirements and hose lengths. The CD2 Chemdose eliminates those limitations by functioning as a hose end unit. The CD2 can be […]
