  • Increasing the daily light integral

    Published on August 6, 2021
    The daily light integral (DLI) refers to the cumulative amount of light received per day, which influences the quality and yield of horticultural crops. This article discusses ways to increase the DLI for plants grown in greenhouses.

  • LEDs: More than μmol×J–1

    Published on July 7, 2021
    Light-emitting diodes (LEDs) are known for their efficiency at converting electricity into light. While efficacy is a very important consideration, there is more to them than just their μmol×J–1.

  • The indoor lighting guide: Growing seedlings under LEDs

    Published on July 1, 2021
    This 24-page guide provides research-based information about producing young plants indoors (without sunlight) under LEDs. Developed in partnership with GrowerTalks magazine.

  • Greenhouse Pest Management with Insecticides

    Published on June 14, 2021
    Research-based information is presented on how to manage greenhouse insects and other pests including thrips, aphids, whiteflies, mites, fungus gnats, and mealybugs.

  • Challenges of growing vertically in greenhouses

    Published on June 8, 2021

  • “Hidden” benefits of supplemental lighting

    Published on April 7, 2021
    High light can at least partly decrease the effects of other environmental parameters on greenhouse crops. These can be considered “hidden” benefits because the effects are often not obvious.

  • Sole-source (lighting) for seed

    Published on April 5, 2021
    By producing plants indoors under sole-source lighting, not only can we control plant traits by manipulating the light quality and/or quantity. but we can potentially produce more resilient plants.

  • Maximizing photosynthesis, minimizing respiration

    Published on March 8, 2021
    Conceptually, anything growers can do to increase photosynthesis and decrease respiration can increase growth, leading to thicker stems, faster rooting, more branches, and more and larger flowers and fruits
