Lighting for Horticulture – Light and the Environment

Lighting for Horticulture – Light and the Environment

This third article in the “Light Physics 101” series goes beyond light itself to explore the other variables and environmental factors—like temperature, humidity, soil acidity and carbon dioxide—whose complex interactions, when carefully controlled and calibrated, promote plant health and reproductive viability.

How do other factors such as temperature, PH, humidity and CO 2 interact with light and affect plant growth?
