Rough’s Poly Arch Design Is For Poly-Covered Roofs

Rough Brothers recently introduced a new wide span addition to its line of Poly Arch gutter-connected greenhouses. Developed to meet the needs of cost-conscious growers, the wide span Poly Arch structure is engineered specifically for poly-covered roofs and is available in either 30-foot or 35-foot widths. With more than 14 acres ordered or installed over the past year, this product has quickly become one of Rough’s most popular featured structures. Insomuch as growers considering our new Poly Arch design are most impressed with the cost benefits this package offers, the real success of this house lies in its simplicity. With limited components, and an all-bolt-together design, this system is not only competitively priced but also easy to build. Not lacking for strength, the frame incorporates heavy-duty 4-inch round gutter columns on 12-foot centers, 238-inch round pipe Gothic arches on 6-foot centers, easy-to-walk-in gutter assemblies and either a cable cross tie […]

Beneficial Controls Guide Greenhouse Design

Every Nexus project is different. There is no such thing as cookie-cutter. We welcome the challenges that our customers bring to us. Recently we completed a project for Tallman Construction as the general contractor for Sun Rain Seed Potatoes. There were several unique design elements that made this project interesting. The first was the need for insect screening so the operation could use beneficial controls. The whole south end of the greenhouse is designed with bug screening, so every bit of air is filtered to allow only a minimum amount of insect penetration. Tallman also needed warehouse space so we designed the project so the greenhouse was extended and covered with insulated metal covering. It makes for a very attractive design for a multiple-use area. That warehouse is then connected into the company’s two-story office building. The traffic flow was thought through and designed into the plan. Lastly, each greenhouse […]

GGS’ Open-Roof Greenhouse Design Helps Hendriks Greenhouses With Drip Control Problem

Many growers are concerned about maximizing greenhouse ventilation. In some maximum ventilation designs, condensation control is sacrificed and dripping becomes an issue. This was the case for Hendriks Greenhouses, until the operation approached GGS Structures Inc. to help solve the problem. Hendriks Greenhouses, located in Beamsville, Ontario, wanted a design that balanced both ventilation and condensation control, and GGS responded with the open-roof greenhouse design. “Having worked with GGS over the years with the gutter-vented greenhouse, we knew it was possible to work with them and get a nice dry open-roof house as well,” says Craig Barlow, operations manager at Hendriks Greenhouses. GGS created the open-roof design in response to growers’ increasing concerns about ventilation with drip control. “The GGS open-roof greenhouse design provides an optimal system to maximize ventilation while maintaining a smooth surface on the poly and good roof pitch for condensation control,” says Michael Camplin, sales manager […]

How To Successfully Upgrade A Greenhouse

You’ve determined you’re ready for a greenhouse upgrade, you’ve got the financing in place, and now you’re finally ready to implement the changes. But actually carrying out the retrofit often is the most overwhelming part of the project, especially when your livelihood depends on getting your operation back up and running as soon as possible. So how do you make sure everything goes smoothly and your business doesn’t miss a beat? It’s all in the planning, says Richard Brigati, owner of White Post Farms in Melville, N.Y. “Without planning, you don’t stand a chance,” he says. “You’ll just constantly be putting Band-Aids on things.” It Takes Proper Planning White Post Farms grows a mix of annuals and perennials at its 3-acre operation. The majority of the plant material is grown for White Post’s garden center, but the operation also sells to landscapers, nonprofit groups and other garden centers. When Brigati […]

Conley’s Manufacturing and Sales has provided the agriculture industry with greenhouse design and technology since 1946. One of Conley’s current projects includes a vast expansion for an operation that has become a perpetual customer, Duarte Nursery Trees and Vines. Duarte Nursery Trees and Vines is a 23-year-old family-owned and operated permanent crops nursery located in Hughson, Calif., just south of Modesto. Crops include grafted grape vines for the wine industry, citrus varieties, almonds, walnuts, olives, pistachios, cherries, blackberries and poinsettias. As the largest permanent crops nursery in the United States with sales growing more than fourfold in less than a decade, it was time to significantly expand the size of the nursery with the addition of several new custom-designed greenhouses.

Rough Brothers Adds Two Product Lines

In the past year, Rough Brothers Greenhouses, a high-end structures supplier, has broadened its product offerings through acquisition, purchasing the assets of both X.S. Smith and Golden Pacific Structures. The strategy serves a couple of purposes for the company, says Commercial Manager Tom Vezdos. “We wanted to be able to cover the U.S. with sales reps. Now we’re able to cover the southern parts of the country we were never able to effectively get to before,” he says. “And we want to be able to provide a structure to everybody in the greenhouse business.” X.S. Smith and Golden Pacific traditionally offered lighter, less expensive greenhouse structures, so adding these product lines gave Rough a more complete spectrum of offerings. “Somebody might just want a Quonset, or they may want a poly arch or an A frame. On the higher end, someone may want a Venlo or an open-roof structure. Quite […]

Greenhouse Covering Released To USA After 29 Years of Success in Europe

Polydress SolaWrap has been successfully used in greenhouses in Europe for three decades and is now being introduced to America. SolaWrap’s unique qualities have led to reported tomato crop advancement in the Mediterranean of three weeks, in the wintertime, in an unheated greenhouse compared to standard greenhouse coverings. Its durability was tested in the extreme heat of Kuwait for a period of 25 years until the outbreak of war destroyed the testing facility. In that 25-year period, the original SolaWrap covering withstood the elements and remained effective. It did not yellow or become brittle or streak. In the converse climate of Manitoba, Canada, where temperatures drop well below freezing, a trial has been in process for more than five years. The results are very promising. Strawberries are growing in this SolaWrap greenhouse in January, and the only heating occurs at night during the dead of winter. However, the greatest test […]

Greenhouse Retrofits And New Builds: Planning Tips

Here are some tips to help you with planning an expansion, reducing operating costs, or improving efficiency. The first step is to know what you want to accomplish. If operation labor reduction is the key motivator behind a retrofit project, then you need to look at how the greenhouse is affecting your labor. The best value for retrofitting will be different than if increasing crop yield is your main goal. Greenhouse Retrofits For Increasing Worker Productivity • Replace stationary benches with rolling benches. In an effort to pack as much production as possible inside the greenhouse, many greenhouse growers leave virtually no space to walk between the crop. With rolling benches, you only need one aisle per house, so you may increase the width of your production aisles without losing any crop production. This enables workers to move more efficiently between the benches. Typically, rolling benches can also offer the […]

Growing Greenhouse Vegetables: Timing The Gaps

For ornamental growers looking for a new product for the gap seasons between traditional crops, vegetables can make a lot of sense. Many of the necessary structures, equipment and techniques are familiar. But there is plenty to learn as well, from nutrition to irrigation strategies to variety selection — a lot of which revolves around timing. We talked with Paul Gallione of Johnny’s Selected Seeds to learn more about the steps he recommends for growers getting started in vegetable production. GG: A lot of the details for adding a crop like vegetables are obviously going to vary for every grower and his own situation. How does timing impact these decisions? Gallione: There’s more to it than just saying, “OK, I’m an ornamental grower and my greenhouse is empty and I’m going to grow vegetables.” Don’t get me wrong — there’s probably a lot of equipment, labor and infrastructure that can be utilized for […]
