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.

  • 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 perils of low (greenhouse) temperature

    Published on February 13, 2020
    There can be some undesirable and insidious consequences if the temperature is lowered too much, or for too long. This article describes some of the pros and cons that can arise from low temperatures, especially in the greenhouse.

  • Greenhouse environment checklist

    Published on October 10, 2019
    Every autumn, ensure greenhouse systems that regulate the major environmental parameters are working well and positioned properly. This article highlights many of the control systems and equipment to check.

  • Accelerating growth: What works and what does not

    Published on April 1, 2018
    The most effective way growers can accelerate plant development is to increase the greenhouse air temperature.

  • 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.

  • High tunnel and outdoor production of cold-tolerant bedding plants

    Published on November 10, 2016
    As greenhouse space becomes limited in the spring, you may consider using outdoor spaces and high tunnels. Read on for insight into the benefits and risks associated with these growing strategies.

  • Using root-zone heating for energy-efficient petunia production

    Published on July 17, 2016
    A new study shows that you can grow your petunias in a cooler greenhouse to save money and still produce a high-quality crop.

  • 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.

  • High Tunnels: Reduce Heating Costs While Improving Bedding Plant Quality

    Published on November 17, 2014
    This is the first article in a two-part series featuring research from Purdue University that focuses on energy-efficient production of cold-tolerant bedding plants.
