New Denver Botanic Gardens Greenhouses Are Standouts
[imageviewer] The Denver Botanic Gardens is an oasis in the middle of the City of Denver. The new, $15 million, 15,000 square foot greenhouse production range and Orangerie officially opened the week of Sept. 20. The project was publicly funded through a voter-approved Better Denver Bond Program that included additional revitalization efforts around the city. Nexus Greenhouse Co. was the design/build/manufacturer of the production range, as well as the Orangerie. There are six Vail, gutter-connected structures in the production range, each 30-feet x 88-feet. They are divided into 12 zones with a 10-foot corridor and a 17-foot gutter height. Glazing is 16-mm impact modified acrylic and Viracon low Solar screen low-E (emissivity) insulated glass.

Ohio State Greenhouses Damaged In Tornado
A tornado ripped through the Ohio Agricultural Research and Development Center (OARDC) on the campus of Ohio State University in Wooster last Thursday, flattening one greenhouse and damaging others. One student suffered injuries, but most of the 400 or so faculty and staff at the facility had already left before the storm arrived. OARDC spokesman Mauricio Espinoza told the Akron Beacon Journal that half of the three-story Agricultural Engineering Building was flattened. Photos of the damage, including a car blown over from a parking lot that rests in front of a research greenhouse, can be seen at Ohio.com.

Aquascape Donates, Installs Rainwater Harvesting System
Aquascape is donating a 500-gallon RainXchange rainwater harvesting system with 20-foot stream to Universal Design Living Laboratory (UDLL), a 3500-square-foot home in Columbus, Ohio. The UDLL project was initiated by Rosemarie Rosetti, a motivational speaker, author and wheelchair user, along with her husband Mark Leder, after a bicycling accident left Rosetti paralyzed from the waist down. The Universal Design Living Laboratory will become a home to Rosetti and Leder upon completion, in addition to serving as a learning resource for builders, designers, architects and consumers. The couple’s mission is to raise awareness of quality indoor and outdoor lifestyle through universal design, green building, safety and healthy home construction practices. Aquascape is inviting a group of Certified Aquascape Contractors to participate in the hands-on training and installation of the RainXchange rainwater harvesting system, which will bring biodiversity and a native aquatic habitat to this suburban property. Rosetti and Leder will be […]

Getting The Most Out Of Light Measurements
Does the quality of your greenhouse-grown plants or number of cut flowers harvested decrease in the winter? Do your cuttings take longer to fully root during certain times of the year? Do you own HID lamps but don’t know when you should use them? If your answer is yes to any of these questions, this article will shine some light on how to solve some of these production problems. In commercial greenhouses, growers can implement several strategies to increase quality and yield, decrease propagation or production time, and enhance root and shoot development of seedlings and cuttings. One fundamental way this can be achieved is by successfully managing and manipulating greenhouse light levels. However, before managing the light in your greenhouse, it is important to know what type of light you are measuring, how to measure it and how manipulating it will affect your crops. Measuring Light 101 The footcandle […]

Embracing Energy Efficiency
For many years, greenhouse owners have stared at their gas-fired unit heaters and watched dollar after dollar escape their vents due to inefficiency. Thanks to the Effinity93 from Modine, owners can now embrace a more energy- and cost-efficient greenhouse solution. The Effinity93 is an efficient gas-fired, condensing unit heater that comes in six models–from 135,000 BTU/hr to 310,000 BTU/hr–all operating at 93 percent efficiency. The 93 percent efficiency rating is a dramatic step forward compared to traditional 78 percent seasonally efficient power-vented unit heaters–and even more so versus 65 percent seasonally efficient gravity-vented unit heaters. So how does that translate into savings for a greenhouse? While savings vary depending on location, in many cases across North America just one Effinity93 heater can save more than $1,000 a year in energy costs. And when you take into consideration the actual number of units required to heat a greenhouse, it isn’t difficult […]

Nexus Supports American Red Cross At OFA
Nexus had a little fun at OFA Short Course this year while raising money for disaster relief for the American Red Cross. At its booth, Nexus had a spinning wheel that allowed people to not only make American Red Cross donations, but also win a few prizes. Ultimately, Nexus helped raise $1,230 for the American Red Cross. The grand prize was a trip for two to either California Spring Trials for growers or to the ANLA Management Clinic in Louisville for retailers. That prize was won by Tom Mahoney of Mahoney’s Garden Centers in Massachusetts. Other growers and retailers went home with prizes ranging from Nexus logo shirts and hats to discounts on their next greenhouse project.
