How much water supply is needed in a peak-use greenhouse per square foot per day?

In a peak-use greenhouse, the water supply typically needed is about 2 quarts per square foot per day. This amount ensures that plants receive adequate moisture to support growth, especially during high-demand periods such as flowering, fruiting, or in the heat of summer when plants transpire more actively.

Providing the right amount of water is crucial for maintaining plant health and productivity. Insufficient water can result in stress, reduced growth, and poor crop yields, while too much water can lead to problems such as root rot and waterlogging. Therefore, a balance, often around 2 quarts, is established based on the average needs of the plants grown in greenhouses during peak conditions to optimize both growth and efficiency in water use.

In context, while other options suggest higher or lower quantities, they do not align with the generally accepted guidelines for maintaining optimal moisture levels necessary for greenhouse crops during peak times.
