Estimating greenhouse supplemental lighting runtime is one of the most practical steps in greenhouse lighting design. After growers know the crop target

Winter and cloudy seasons create one of the most common lighting challenges in greenhouse production: crops may receive enough protection from the

A complete greenhouse supplemental lighting guide covering DLI, PPFD, light transmission, runtime, LED layout, uniformity, crop targets, controls and commercial system design.

Learn the difference between PPFD and DLI, how the two metrics connect, and how greenhouse growers use them for layout, runtime, measurement, and control.

Learn how to calculate greenhouse DLI from canopy PPFD and time, estimate sunlight transmission, find the supplemental-light deficit, and convert it into PPFD or runtime.
