Greenhouse Ventilation & Cooling
The main goal of greenhouse gardening is to maintain an even or optimum growing environment for your plants. One way to accomplish that is by offering ventilation and cooling assistance during the warm, summer months.
ROOF AND SIDE GREENHOUSE VENTING
- Roof venting is still considered the best of greenhouse ventilation systems.A roof vent serves as an escape route, but it also provides a source of cool air intake.
- Individually controlled roof vents allow the intake of cool air to be a gentle flow to bench level, not a strong force that suddenly lowers the temperature.
-
Glass louvers or hinged side venting is also very common at the bench level or lower. Side venting will certainly assist in cooling the greenhouse in the warmer seasons.
- During the spring and summer, direct sunlight can quickly overheat the greenhouse and destroy both plants and seedlings.
- Exterior shading is the most effective method of preventing heat build-up.Shade cloth, or screening material, has been used by commercial growers for many years and is now available for hobby greenhouses.
- Higher density shade cloth is more suitable for orchids or other tropicals.
