Avoiding Overheating

You can block heat using expensive computer or manually operated shades or by applying colored coatings to glass. Shades are prone to operational problems and use energy. Colored coatings need to be removed to maximize light transmission after the hottest time of the year. For existing glass greenhouses, another option is to install clear, colorless window film that will block unwanted heat while allowing in desirable natural light. Once installed, such film may last up to 20 years. It does not need to be removed, does not change the appearance or visual clarity of the glass, does not need special care and will not fail to perform because of computer or mechanical malfunction. Affix it and forget it. Tinted window films do reduce heat into greenhouses, but they can also reduce a significant percentage of visible light through the glass, according to V-Kool President & CEO Marty Watts. “Most conventional […]

Master Builders

While most growers got into the greenhouse business because they love to grow plants, others really take pride in building greenhouses and have dedicated employees and crews. One prime example is George Lucas of Lucas Greenhouse in Monroeville, N.J. While he and his wife founded the business with just 9,000 square feet of greenhouse about 30 years ago, today Lucas Greenhouse spans 630,000 square feet and ranks at No. 100 on our Top 100 Growers. The company has undergone three major buildouts with Nexus Greenhouse Systems since 2002 and just constructed 170,000 square feet of Dual Atrium greenhouses with a glass roof and polycarbonate sides and gables using its own crews. This summer, Lucas will be adding another 130,000 square feet. Where is all this growth coming from? Young plants. Forty percent of production is propagation and prefinished plants, and the rest is finished plants sold to independent garden centers within […]

Building A New Greenhouse

So you’re thinking of building a new greenhouse? Here are some tips I’ve learned building our new propagation range in Fresno, Calif. The first thing on your list should be to create a master plan on how your structures will be laid out now and potentially in the future. This should include all utilities entering the greenhouses and any special requirements for your equipment. You might not build on your greenhouse for a while, but you should always give yourself the option of adding on in the future without any obstructions. Questions you need to address during this process: – Can the new greenhouse(s) be built on our existing property without any modifications? – Do we need to move older structures to accommodate our new greenhouses? To keep the flow of your new greenhouse, it might be better to move some of your existing structures. – What are the timelines to […]

The Liquid Crystaled Greenhouse

The Cleveland Botanical Garden has teamed with Kent State University’s Liquid Crystal Institute in an attempt to examine how greenhouse plants grow under sunlight that passes through liquid crystal windows.  The idea, highlighted in a recent edition of the (Cleveland) Plain Dealer, spawned from the botanical garden’s desire to reduce the cost of energy. If results of the experiment are positive enough, a second experiment will be conducted to determine whether ultraviolet and infrared waves can be modified enough to, perhaps, shorten the time it takes plants to grow.  And that’s where cost-saving enters play. If liquid crystals prove more beneficial in growing plants, greenhouse owners can use them instead of shade cloths to control the amount of sunlight entering their structures.  Liquid crystals aren’t common in greenhouse coverings. They’re usually found in television screens and wristwatches, but that didn’t stop Cleveland Botanical Garden from pursuing this experiment and considering […]

Al’s Loses Roof In Wind Storm

The Statesman Journal in Salem, Ore., reported this weekend that a heavy storm ripped the roof off a greenhouse at Al’s Garden Center and damaged several other structures on the property. According to the article, the garden center’s owner Jack Bigej said the roofs on the 82 greenhouses on the property are built to withstand at least 65 mph winds. Fortunately, none of the damaged structures housed poinsettias. Damage to the poinsettia crop would have been a hard hit to the business, Bigej said in the article. The National Weather Service is working to determine if a tornado touched down in the area. In addition to the production facility in Hubbard, Ore., near Woodburn, Al’s has retail locations in Portland’s suburbs Sherwood and Gresham. Al’s Garden Center happens to be our October cover story.

Growers And Retailers Share Snow Stories

On The Radio In Buffalo We are a full-service retail florist in Buffalo, N.Y., with a half acre of greenhouses. We had our localized storm on Oct. 12 and 13, where 22 inches of snow brought down tree branches that had not shed their leaves. Eighty percent of the area was without power for several days and we lost 240 panes in the greenhouses. Hortica Insurance took care of this nicely. For Valentine’s Day, we had about 400 deliveries to make in one day. The threat of the storm was frightening, but love must prevail. Our talk radio station, WBEN, where we were advertising called my brother Frank (the oice in our ads and dispatcher of our drivers) on Tuesday afternoon to ask if they could do an on-air phone interview on Valentine’s morning, which he agreed to. The next morning they announced they would be interviewing Frank Mischler of […]
