2-25-2016 / Greenhouse Ventilation:
-----------------------------------------------------------------------------------------------
The ventilation system in a greenhouse plays a critical role in your plants health and crop production. Slow growth, poor yields and the plants overall health can be attributed to the ventilation system.
Ventilation systems in greenhouses actually serve four functions:
* Temperature control
* Humidity control
* CO2/oxygen replacement
* Air circulation.
Temperature Control:
Greenhouses trap solar radiation and raise the temperature in the environment (Greenhouse effect). If this heat is not removed from the environment it can cause undesirable conditions for plant growth or worse.
(Automatic roof vent openers should be used)
Humidity Control
Just about every mold, fungus, and mildew can thrive in high humidity conditions. Plants transpire moisture that, if not removed, can build up in a greenhouse.
(Roof Vents, Louver Windows, Fans, Solar roof fans are available)
CO2 / Oxygen Replacement
Plants use CO2 which they acquire directly from the air. Maintaining an adequate level of fresh air intake guarantees sufficient CO2 levels for plant growth.
Oxygen is required for the roots to continuously grow.
Air Circulation
Air circulation, or air movement strengthens the cell walls of a plant’s stem.
Many vegetable and ornamental plants are pollinated from the air or wind movement inside the greenhouse. Oscillating fans within a greenhouse are a great tool to help create air movement.
