Prospiant’s Zephyr greenhouse offers the most cost-effective solution for natural ventilation. Top-ridge vents allow heat to escape at the optimum point, and are great for dehumidification and ventilation, even when the gutters are full of snow. The vertical vent design creates the chimney effect at the peak, allowing hot air to escape at the highest point in the greenhouse—not at the lower gutter area, as in competitors’ gutter-vented designs.
