For any type of grow room, proper ventilation is critical for the health of the plants. The amount of ventilation, like the amount of light and water required, does vary based on the type of plant and the stage of growth.
Growing plants indoors is more challenging than outdoor environments for several reasons. While there is the ability to control the temperature and the moisture, it is more challenging to get the variations in light and the air circulation around the plants.
Airflow is Crucial for Growth
The key with any type of grow room ventilation system is to be able to provide airflow throughout the area and around the plants without creating high volumes of moving air. The circulation is essential to prevent mold, mildew, and other types of fungus from becoming established on the plants or in the soil or growing medium.
On the other hand, too much air movement can inhibit pollination and growth, and this can vary based on where the plants are positioned in relationship to the fans or ventilation system exhausts. The ideal grow room ventilation system circulates the air without creating excessive air movement, providing a constant source of CO2 for the plants while also eliminating excessive areas of heat, cold spots, or areas of high humidity that allow the growth of bacteria, fungus, and mold.
The use of a top grow room ventilation system is also linked to fewer issues with harmful insects in the grow room. Insects tend to thrive on high heat and high moisture pockets, and eliminating these can help to control the bug populations without the need for pesticides.
