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.

  • Energy-efficient annuals 2: Scheduling bedding plants

    Published on April 22, 2009
    Greenhouse temperature influences plant development and energy consumption for heating. When producing a crop, delivery of low temperatures may actually be more energy intensive than warmer temperatures.

  • Controlling height with temperature drops

    Published on April 17, 2009
    Temperature drop is the practice of lowering the temperature, typically by 5-15 degrees F, before sunrise. Generally, the greater the magnitude of the temperature drop, the stronger it suppresses plant height.

  • Energy-efficient annuals 1: Perfecting temps and light

    Published on March 29, 2009
    Learn the concepts of how temperature and daily light integral influence growth and flowering of annual bedding plant crops.

  • Calculating ADT (average daily temperature)

    Published on December 17, 2008
    Average daily temperature is a crucial factor in crop time and plant development. Learn to calculate it and how it affects your growing schedule.

  • Fanning uniformity in the greenhouse

    Published on May 17, 2008
    Horizontal airflow fans, which help create a more uniform greenhouse environment, can be a boon if used properly.

  • Responses to temperature & light

    Published on January 29, 2008
    Longer growing time at cooler temperatures or shorter growing time with warmer temperatures? That question is addressed for annual bedding plants in this article.

  • Using +DIF to lower fuel costs

    Published on February 17, 2007
    As energy costs continue to be a concern, consider growing crops at a warm day temperature and a cool night temperature to help reduce fuel costs.
