Circulation ensures all plants receive high-quality air. The ideal cross-breeze travels at 2-3 mph. This constant air circulation will provide carbon dioxide to all corners of the house. In addition, it helps to balance the temperature and humidity, ensuring an even growing environment.
Air circulation does more than just influence the environment. Wind is a natural pollinator. A gentle breeze shakes the plants to move pollen around the house, fertilizing the plants. This moving air will ruffle leaves and create stronger plants with strong root systems. They are more resilient against pests like white flies and aphids, which find it difficult to thrive in such an environment.
