In this first in a series of “Light Physics 101” articles, basic concepts are explored. What are photons? How is light measured, and what instruments and equipment are used to do so? And how does this all relate to horticulture?
The second article in the “Light Physics 101” series explores the mechanics of how plants respond to and interact with light, and the lighting conditions required to optimize the production of foliage and fruit.
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?
