  • 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.

  • 10 lighting tips to help your bottom line

    Published on April 24, 2005
    Suggestions and advice to make the most of the light your plants receive.

  • Lighting greenhouse vegetables

    Published on December 7, 2011
    The primary way to increase fruit yield (fruit number and/or size) is to increase the amount of photosynthetic light provided to plants.

  • How much supplemental lighting do you need?

    Published on December 17, 2019
    Several factors need to be considered when choosing a supplemental lighting system, and arguably the most important one is to determine what light intensity you want to deliver. This article provides steps on how to do that.

  • Effective long-day lighting fixtures

    Published on November 9, 2020
    A large number of ornamental crops flower earlier when grown under long days. This article describes the major considerations when selecting a photoperiodic lighting system to regulate flowering.

  • Control flowering with LEDs

    Published on March 23, 2014
    Is it worth paying extra for LEDs? Researchers at Michigan State University found that the long-term benefits may outweigh the up-front costs.

  • DLI 'requirements'

    Published on May 10, 2019
    This article provides daily light integral (DLI) guidelines to produce plants of at least moderate quality, assuming plants are grown at moderate temperatures.

  • Temperature and light on bedding plants

    Published on July 29, 2003
    Michigan State University research shows what effects temperature and daily light integral have on bedding plant production.

  • Common plant production acronyms

    Published on May 8, 2020
    This article briefly defines 20 acronyms (abbreviations formed from the initial letters of other words) commonly used when discussing controlled-environment production of plants.

  • The importance of light uniformity

    Published on March 3, 2017
    Managing light is obviously critical to the production of crops grown in controlled environments. When considering the different dimensions of light, we often overlook the importance of light uniformity.

  • New, high-resolution, interactive DLI maps

    Published on October 10, 2018
    New maps of the photosynthetic daily light integral (DLI) in the United States have been developed and are now available online.

  • 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.

  • 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.

  • Maximizing photosynthesis to improve growth

    Published on December 23, 2012
    Plant growth is suppressed when light, CO2, and/or water are not sufficiently available inside greenhouses.

  • Developing new plant lighting standards

    Published on October 23, 2017
    Standards are developed so there is consistency and conformity in products to improve confidence and comparability in new technologies.

  • 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

  • Lighting the way with LEDs

    Published on July 10, 2012
    Light-emitting diodes (LEDs) are one of the trendiest technologies in the greenhouse industry. There are particularly interesting opportunities with LEDs in the production of young plants and highwire vegetable crops.

  • UV radiation and applications in horticulture

    Published on May 1, 2018
    Ultraviolet (UV) radiation is outside of the photosynthetically active waveband, but it is biologically active and regulates plant growth.

  • Far red is the new red

    Published on February 6, 2017
    Adding far red to red and blue light from LEDs brings control of plant growth to the next level.

  • Interactions of light, CO2, and temperature on photosynthesis

    Published on June 23, 2015
    Often times, we simplistically think about light as the driver of photosynthesis, and temperature as the key to control crop timing. Although that’s generally true, other cultural and environmental factors influence crop growth and quality.

  • LEDs in floriculture

    Published on June 24, 2009
    LED technology, first used in the mid-1980s, has come a long way and may make its way into the greenhouse in coming years.
