Agra Tech`s Continental Greenhouse is a Gothic Gutter Connect structure designed to be covered with poly. A 4` wide continuous single or double ridge vent can be added to provide excellent natural ventilation. Extra large gutters add strength and carry 60% more runoff away from the greenhouse.

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.

The Insulator Greenhouse is a Gutter Connected, Commercial Structure available as Code or Non-Code structures.  This house provides quality, strength and ease of construction with natural ventilation. The Insulator Greenhouse performs well in all climates from Alaska to Mexico and beyond.

Shade curtains play an important role in greenhouse cooling. On a bright sunny summer day, a 30’ x 100’ greenhouse will gain up to 32 million BTU of heat due to solar gain. (Solar gain is sunlight that gets converted to heat.)  Shade fabric with aluminum strips reflect excess light up away from the plants. The fan and pad cooling system will not need to be turned on as soon and will run for less time with a shade curtain.

This is an inexpensive yet sophisticated system that utilizes gas-fired blower heaters with ducts, plenums, and punched convection tubes to direct the heat under the bench to the crop zone.
