2025年1月16日 · Enter the name of your plant below to quickly find its recommended PPFD and the recommended daily light integral (DLI). If you're like us — you want to optimize the PPFD and DLI levels for your plants for the best results in both plant growth and electricity consumption.

2021年9月20日 · Learn how to measure, calculate, and use daily light integral to provide your plants with perfect lighting.

2024年12月17日 · Read along as we describe recommended DLI values for cannabis from seedling, to vegetative, to flower (a.k.a. bloom), to harvest. You'll learn what the DLI is, how it affects plants, how it can save you money, and how you can optimally use your grow lights by measuring and adjusting the DLI.

Check your Daily Light Integral with our free DLI Calculator to gain insight on how much light is available for your plants.

The DLI combines light intensity (PPFD) with the lighting duration (photoperiod) over a 24 hour window and is measured in the unit of mol/m²/d i.e. light per area per day. Ultimately, providing the right DLI level for your plant is what you must do for optimal plant lighting.

Jim Faust and colleagues at Clemson University have developed maps of monthly outdoor DLI throughout the United States (Figure 1). These maps illustrate how latitude, time of year, length of day (photoperiod), and cloud cover influence DLI and vary from 5 to 60 mol∙m-2∙d-1.

2024年12月16日 · The daily light integral (DLI) specifies the usable light received within a 24 hour window. Understanding and optimizing DLI is crucial for healthy plants and bountiful plant yield.

This DLI chart is plant-specific. It lists many greenhouse crops, showing the minimum DLI levels that the plants would need to achieve an acceptable quality of growth. These dimmable LEDs are an excellent way dial in the perfect PPFD levels without needing to alter the hanging height.

2021年2月27日 · DLI is now a common term (measurement) used by commercial growers and plant scientists. In this article, an interactive and useful tool made by Joanne Logan and James Faust to check the Annual and Monthly DLI Values (mol/m2/day) in the United States of America.

PPFD = Photosynthetic Photon Flux Density: The amount of light that actually reaches your plants within the PAR region or the number of photosynthetically active photons that fall on a given surface each second. The PPFD is expressed in μmol/s. m2.
