The Dallas Arboretum opens a giant new greenhouse so it can grow its own plants

Dallas Morning News 2019

A new technologically advanced, 17,000-square-foot greenhouse will nurture new plants before they grace the Arboretum’s walkways and gardens.

GrowerTalks June 2018

Nearly 45 years ago, Wadsworth Control Systems installed its first curtain system—a blackout at Irwin Greenhouses in Canyon, Texas. The system ran on a time clock to maintain a balance of day and night, creating the necessary environment for the crop of kalanchoes, chrysanthemums and poinsettias. To a lesser degree, the curtain addressed a second need, one that had just arrived in every American’s life.

The Newest Control from Wadsworth Control Systems: Seed

CNGA LooseLeaf Tech News

Greenhouse automation was pioneered in Colorado, and Wadsworth Control Systems was the first company to design and build greenhouse automation products in the U.S.  This contribution earned our father, George Dean, a place in the Horticultural Hall of Fame in 1992.

That set a high bar for the third generation of the Dean family. With the release of the Seed control, we believe we’ve made another significant contribution to the greenhouse industry.

Curtain Checkup

With energy costs increasing and little relief in sight, everyone is looking for ways to reduce heating costs. One way of conserving energy is the use of an energy curtain in the greenhouse that, when pulled closed at night, creates an attic of air that acts as an added layer of insulation. Any future greenhouse that growers may be designing or planning should allow for at least a single-curtain system, whether they are being installed initially or at a later date. Preplanning will allow any greenhouse business to then add the first or even a second system without too much retrofitting

Greenhouse Upgrades Part I

If I were a grower, I would want to put my precious capital into something that helped me reduce costs, reduce labor and increase quality all at once. Hot water heaters can do just that.

To do a good job of heating your greenhouse space means delivering the heat evenly. The heat should be delivered in a way that allows your plants to take away the most benefit possible. We call this “distribution efficiency.” If you heat with hot air furnaces, no matter the type or efficiency, your distribution efficiency is probably around 50%. This means of all the heat you generate, only about 50% is put to good use by your plants. The rest is lost to leakage in your glazing, or rises immediately to the peak, where it does nothing beneficial for you.

Using Temperature to Control Growth

An early morning DIF or DROP, which lowers the greenhouse temperature before sunrise, can help control plant growth and save on energy costs.

Reducing temperatures at sunrise creates a morning DROP and reduces stem elongation.Much has been written about DIF, which is defined as the difference between day and night temperatures or day temperature minus night temperature. A negative DIF, the result of a night temperature that is warmer than the day temperature, prevents stem elongation in many crops. Considering today’s increasing fuel prices, efforts to use negative DIF to keep greenhouse temperatures warmer at night isn’t necessarily a good business practice. Many growers have decided it’s not worth the extra cost.
