Why Do You Need to Ventilate Grow Rooms?
Unlike outdoor plants that are exposed to breezes and the wind, plants indoors lack proper airflow. When airflow around and through plants is restricted, your indoor growing space can remain damp for extended periods. A damp environment is a perfect setup for the growth of fungal diseases like black spots and mildew.
Plants also need fresh air to photosynthesize. A flow of fresh air then helps turn light, water, and carbon dioxide into food, helping plants grow.
