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.

Resources

  • Temperature integration

    Published on February 5, 2018

    Plants integrate and respond to temperature over an extended period, and not just the day or night temperature.

  • Bedding plants with high base temperatures

    Published on December 14, 2016

    In the late winter and spring, many greenhouse growers produce a wide variety of species and cultivars, many of which are annual bedding plants. Crops can have different growing and flowering requirements, so plants shouldn’t all be grown the same way.

  • Crops with relatively low optimum temperatures

    Published on May 17, 2015

    At temperatures above the optimum, plants experience stress and the rate of development begins to decrease. Learn which crops grow best at relatively cool temperatures.

  • Dealing with the cold

    Published on January 17, 2015

    It’s naturally tempting to reduce the greenhouse temperature so that less energy is consumed per day, but there are consequences to such actions that growers should understand.

  • Managing temperature during propagation

    Published on December 19, 2014

    Temperature primarily drives the rate of root and shoot development while light provides the energy to promote that growth. When one of these environmental factors is not optimized, rooting is delayed.

  • 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.
