Greenhouse Temperature Management

Temperature controls the rate of plant development and thus, crop timing.  Temperature can also influence extension growth of plants, greenhouse energy consumption, and crop quality attributes.  Additional information on temperature, including crop responses and greenhouse energy consumption, are listed in the articles below.  Additional resources follow.

  • Growing your crops above their base temperature

    Published on November 17, 2014
    Is lowering temperature set points in the greenhouse the best option for you to combat rising heating costs?

  • Dealing with high temperatures

    Published on May 17, 2014
    Some of the most common heat-stress symptoms on ornamentals include lower-leaf yellowing, thin and elongated growth, delayed flowering, and small flowers.

  • Cold-intermediate bedding plants

    Published on February 22, 2014
    Bedding plants that stop developing at moderately low temperatures can be labeled as cold-intermediate plants. This categorization is based on estimates of base temperatures derived from research data primarily generated at Michigan State University.

  • Cold-tolerant bedding plants

    Published on January 22, 2014
    Bedding plants that stop developing at low temperatures can be labeled as cold-tolerant plants. This categorization is based on estimates of base temperatures derived from research data primarily generated at Michigan State University.

  • Cold-sensitive bedding plants

    Published on December 22, 2013
    Bedding plants that stop developing at a relatively high temperature can be labeled as cold-sensitive plants. This categorization is based on estimates of base temperatures derived from research data primarily generated at Michigan State University.

  • Temperature on chyrsanthemum

    Published on July 17, 2013
    Once flower buds are visible, adjusting the growing temperature has little or no impact on time to flower unless plants are held at low temperatures (50° F or less).

  • Wave petunia smart scheduling

    Published on March 22, 2013
    We quantified the effects of temperature and photosynthetic daily light integral on flowering time and characteristics of 15 Wave petunia cultivars, then generated temperature-based flowering time models for more predictable greenhouse scheduling.

  • Manipulating day and night temperatures to control flowering and heating costs

    Published on February 22, 2013
    The difference between the day and night temperature influences plant height of many floriculture crops, as well as greenhouse energy consumption for heating.

  • Plant temperature under greenhouse curtains

    Published on October 17, 2012
    Retractable energy curtains save energy costs by serving as an insulative layer and reducing the amount of space heated. In addition, plants under the curtains can be at least a few degrees warmer than plants not under a curtain.

  • High-temperature stress of bedding plants

    Published on May 17, 2012
    There are some bedding plant crops that tolerate high temperatures quite well, while others develop heat stress symptoms at lower temperatures.

  • Are you recognizing your heating costs?

    Published on November 17, 2011
    Crop heating costs increase as production time increases, the size of the container increases, and the earlier in the spring that plants are finished.
