  • 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.


  • Ornamental photoperiodic lighting strategies

    Published on February 5, 2018

    Roberto Lopez discusses the photoperiodic response groups of a variety of ornamental crops. He also discusses strategies and equipment to create long days in greenhouses.

  • Optimizing LED lighting for flower crops

    Published on July 1, 2021

    Questions abound when considering use of LED lighting. Choices of fixtures and light quality can be very confusing. In this 45-minute video presentation, Dr. Erik Runkle simplifies the selection and use of LEDs, both indoors and in greenhouses.

  • How to Measure Greenhouse Light

    Published on February 3, 2018
    Are you providing too much light and wasting electricity by operating your supplemental lighting when it is not required? The only way to answer this and many other light questions is to learn how to select and effectively use quantum sensors.

  • How Adding Far - Red Radiation to Supplemental Lighting Affects Plugs

    Published on August 13, 2020
    The majority of LED supplemental lighting fixtures on the market provide either a mixture of blue and red radiation with or without green radiation (white LEDs). This can potentially affect subsequent flowering of long - day plants.

  • Controlled Environment Agriculture (CEA) Carbon Dioxide Injection

    Published on April 13, 2019
    Is carbon dioxide enrichment beneficial for indoor production of basal seedlings?

  • Moving Indoors

    Published on December 8, 2017
    How does light quality, light quantity and carbon dioxide influence young ornamental plant production in greenhouses and indoor controlled environments?

  • Producing High Quality Plugs Part 2

    Published on August 5, 2017
    In this article, we will discuss how continuous 16-hour or instantaneous threshold supplemental lighting from HPS lamps and LEDs and photoperiodic lighting influence plug quality and subsequent flowering.

  • Producing High Quality Plugs Part I

    Published on September 4, 2017
    In this article, we will discuss how continuous 16-hour or instantaneous threshold supplemental lighting from HPS lamps and LEDs and photoperiodic lighting influence plug quality and subsequent flowering.

  • Forcing Long-Day Perennials into Flower with High-Intensity LEDs

    Published on October 3, 2019
    Providing long-day perennial plants with supplemental lighting containing greater than 15 μmol∙m–2∙s–1 of blue light is as effective at inducing flowering as low-intensity day extension lighting and supplemental lighting from HPS lamps.

  • LEDs vs. HPS lamps: A reality check

    Published on June 23, 2014
    With all of the promise and potential of LEDs, some myths and misconceptions are being perpetuated - hence the need for a reality check.

  • Lighting young plants indoors

    Published on February 4, 2019
    Part 1 of a 5-part series is an introduction to producing young plants indoors under fully controlled environments.

  • 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.

  • Including far red in an LED lighting spectrum

    Published on September 9, 2019
    Growers sometimes wonder whether it is beneficial to include far-red radiation in a light-emitting diode (LED) spectrum. Not surprisingly, it depends on the application and crop.

  • Indoor propagation

    Published on July 14, 2020
    High-value crops can be propagated indoors, inside refrigerated growth rooms and without sunlight. This article briefly lists some of the important considerations for an indoor propagation facility.

  • 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.

  • The red to far red ratio

    Published on May 23, 2011
    Plants absorb and use most of the red light available to them for photosynthesis, but reflect or transmit most of the far-red light.
