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.

“I can’t possibly afford that,” they think
The Latest Updates in Environmental Greenhouse Controls, Greenhouse Grower, Technology
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
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
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.
