The Agra Tech Sawtooth Greehouse is a low profile single slope truss. Heated air travels up the roof slope away from the plants.
The two biggest advantages of the Sawtooth design are that it is easy to install exhaust fans mid-house in the vertical wall above the gutter and that it is designed with columns that can continue through the roof to attach an energy truss outfitted with an exterior curtain.
With a vent or opening wall on the windward sidewall and vent on leeward roof, excellent natural ventilation is achieved for happier plants and reduced cooling costs.
"With Agra Tech's support and guidance, these greenhouses are now a reality," Dyer said. "The people at ATI are amazing to work with, because this was a nine year journey and they facilitated every step of it. They understand the educational system because they have worked with high schools and universities over the years. Kent Wright really helped us to learn every aspect of the greenhouse industry, from permitting all the way to dealing with issues and problems and troubleshooting during the entire process."
