Abstract
Photosynthetically active photon flux density (PPFD) provided to plants from a grow light may be calculated based on light-canopy distance measurements, intensity measurements around the plants, and a known shape or distribution of light at the measured distance from the grow light. A controller and a method of controlling one or more grow lights can employ closed-loop techniques that repeatedly measure and adjust light until a desired PPFD is achieved and then maintained.
