  • Light Management in Controlled Environments

    MSU Extension’s floriculture educational and applied research programs help improve greenhouse crop production and business management by providing trusted information on new production techniques and management strategies.


  • Investment considerations for greenhouse lighting

    Published on October 11, 2017
    Many growers install and operate supplemental (photosynthetic) lighting to increase crop quality and yield. This article describes some of the factors to consider when investing in a supplemental lighting system for greenhouse crop production.

  • Boom lighting

    Published on July 23, 2015
    We have developed some general guidelines based on limited research with simulated boom lighting, studies with cyclic lighting, and grower experiences.

  • Red light spectrum - Role of far red radiation

    Published on November 9, 2016
    What are the potential benefits for including far-red radiation when growing seedlings indoors?

  • The economics of lighting young plants indoors

    Published on June 12, 2019
    This article provides the framework of the economics of indoor lighting of young plants (transplants). It includes example costs for an indoor plant factory in Japan, and provides highlights for indoor lighting used by two commercial growers in the U.S.

  • Grower 101: Controlling photoperiod

    Published on October 24, 2002
    Since many important “cash” crops are photoperiodic, a basic knowledge of manipulating daylength is essential.

  • An update on LED lighting efficacy

    Published on July 5, 2018
    In plant lighting, the photosynthetic photon efficacy of a fixture quantifies how effectively a fixture converts electricity into light useful for photosynthesis. This article provides an update the efficacy values of LEDs as of 2018.

  • A little far-red light goes a long way

    Published on May 3, 2019
    Part 4 of a 5-part series presents information on how a relatively low intensity of far-red light influences seedlings grown in fully controlled, indoor environments.

  • Light it up!

    Published on July 24, 2006
    Erik Runkle talks about how to measure and maintain light for new and learning greenhouse owners.

  • Factors that influence leaf coloration

    Published on November 15, 2017
    Growers usually focus on quality attributes that relate to flowering, but this article reviews cultural and environmental factors that influence foliage color.

  • Plant lighting efficiency and efficacy

    Published on July 10, 2017
    Plant lighting continues to be a hot topic, especially as light-emitting diode (LED) technology continues to advance. Learn more about how electric lamps convert electricity into photons of light useful to plants.

  • DLC requirements for LED fixtures

    Published on December 5, 2018
    This article highlights the DesignLights Consortium's (DLC's) requirements for testing and reporting horticultural lighting fixtures that contain light-emitting diodes (LEDs).

  • Green and blue LED lighting

    Published on March 6, 2019
    Indoor production of leafy greens, Part 2 of 4: How green light affects lettuce growth can depend on blue and red light.

  • Is green light useful to plants?

    Published on June 17, 2019
    There is some confusion about the efficacy of green light at promoting photosynthesis. This article explains why and how green light is useful to plants.

  • LIP it! (Limited inductive photoperiod)

    Published on January 24, 2008
    Providing a limited inductive photoperiod (LIP) can produce compact long-day plants and energy-cost savings.

  • Leafy greens: Green & far red LED lighting

    Published on February 1, 2019

  • What is the ideal lighting spectrum?

    Published on March 16, 2020
    With LEDs, we can tailor the light spectrum to elicit specific growth responses. This article discusses some of the considerations to identify an “ideal” plant lighting spectrum. As you will read, it’s highly situational.
