What does container capacity refer to?

Container capacity refers to the maximum amount of water that the container can hold. This measurement is crucial for effective greenhouse management, as it directly influences the watering schedule and overall hydration of the plants within the container. Understanding the container's water retention ability helps growers determine how much water to apply without overwatering or underwatering, which can significantly impact plant health and growth.

While space for plant roots, volume of soil media, and the ability to support fertilizers are important aspects of container gardening, they are not the primary definition of container capacity. The focus on maximum water retention emphasizes the importance of moisture availability to plants as a key factor for successful cultivation in a containerized environment.
