How to Convert Sunlight Hours to Grow Light Hours
To calculate the grow light hours needed when:Plant DLI requirement = 25 mol/m2/dayGrow light PPFD = 600 μmol/m2/sYou can use this formula:Grow Light Hours = (DLI Requirement) / (Grow Light PPFD x 0.0864)
Understanding Photosynthetic Radiation Terms
Bruce Bugbee, president of Apogee Instruments, wants to help everyone understand the confusing terms used to measure light that plants use for photosynthesis. Over the years, these terms have changed, and it's important for growers to know what they mean. A Brief History In the 1960s, scientists used a device...
