  • 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.


  • 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.

  • 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.

  • 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.

  • 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.

  • Greenhouse shading options

    Published on March 24, 2008
    As spring approaches and days get gradually longer, growers need to look at ways to limit the light and heat that affect their most sensitive crops.

  • LEDs: Blue & far-red light

    Published on April 10, 2019
    Part 3 of a 5-part series summarizes results from an indoor lighting experiment with floriculture crop seedlings, where we determined whether blue light could nullify the effects of far red on stem elongation, without inhibiting flowering.

  • 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.

  • Lighting metrics... and what matters

    Published on October 23, 2015
    This article discusses some of the metrics used to describe or quantify the light emitted from various fixtures (or LED arrays), some of which are highly relevant to plant applications and others that are only applicable to people.

  • Sole-source lighting of plants

    Published on September 13, 2017
    Sole-source lighting is a term used to describe the deliver of light to plants that do not also receive light from the sun. In other words, electric lighting is delivered indoors and provides the sole source of light for plant growth and development.

  • 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.

  • Strategies to shorten crop production time

    Published on October 6, 2021
    This article briefly summarizes how genetics, transplant size, and cultural and environmental conditions can shorten, or in some cases unintentionally lengthen, the production time of crops grown in greenhouses.

  • Leafy greens: Carbon dioxide injection

    Published on April 1, 2019
    Indoor production of leafy greens, Part 3 of 4: Is carbon dioxide enrichment beneficial for indoor production of basil seedlings?

  • 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.

  • Light it up!

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

  • White LEDs for plant applications

    Published on November 12, 2018
    Many horticultural lighting fixtures combine blue and red LEDs. However, there are merits to using fixtures that partly or completely contain white LEDs.
