Passive Ventilation Concept Located nearly at sea level about 25 miles east of the Sarasota coast on the Gulf of Mexico, Enza Zaden’s Myakka City, Florida, location presents a favorable climate for this effort, though not without its challenges.

Mild winters bring an average low of 48F (lowest recorded 18F) and five days per year with below freezing temperatures.

That’s balanced by high average annual temperatures of 92F. The highest recorded temperature reached a steamy 105F, and they see approximately 134 days per year at about 90F.

Plus, it’s one of the highest light environments on the east coast.

Those warm temperatures are assets; heavy rains and frost threaten production.

We use 5 gutter connected, 28’ wide by 150 long tunnel spans that are covered in a single layer of polyethylene with 88% light transmission.

With the use of roll up doors, arched end cap vents, and the use of Svensson’s OLS30 shade cloth over the trellis we successfully achieve a “Passive Ventilation” system that keeps optimal temperature in the growing zone.

The porous ceiling of the shade cloth inside the tunnel creates a barrier with the hottest air being concentrated in the attic space and ventilated out through the arched end cap vents by wind and buoyancy.
