  • Why use Virtual Grower?

    Published on October 17, 2009
    The Virtual Grower greenhouse simulation software translates your structure’s data and manipulates it to help calculate costs and make choices to be more energy efficient.

  • 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.

  • Energy-efficient annuals 12: Pentas & verbena

    Published on February 22, 2010
    Researchers from Michigan State University present research-based information for scheduling pentas and verbena in an energy-efficient and predictive manner. Part 12 of a 12-part series.

  • Energy-efficient annuals 3: Marigolds

    Published on May 22, 2009
    Researchers from Michigan State University present research-based information for scheduling marigold in an energy-efficient and predictive manner. Part 3 of a 12-part series.

  • 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.

  • Energy-efficient poinsettia production

    Published on August 8, 2009
    As fuel prices continue to soar, finding ways to limit energy consumption in the production process of poinsettia has never been more important.

  • 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.

  • Energy-efficient annuals 7: Geraniums & zinnias

    Published on September 22, 2009
    Researchers from Michigan State University present research-based information for scheduling geranium and zinnia in an energy-efficient and predictive manner. Part 7 of a 12-part series.

  • Energy-efficient annuals 5: Ageratum & cosmos

    Published on July 22, 2009
    Researchers from Michigan State University present research-based information for scheduling ageratum and cosmos in an energy-efficient and predictive manner. Part 5 of a 12-part series.

  • 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.

  • 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.

  • 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.

  • Measuring greenhouse temperature

    Published on March 17, 2011
    The single largest advantage of using greenhouses to grow ornamental and food crops is the ability to provide desirable temperatures for plant growth and development.

  • 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.

  • 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.

  • 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.

  • Temperature effects on floriculture crops and energy consumption

    Published on November 15, 2006
    This article reviews the effects of temperature on production time of floriculture crops, especially annual bedding plants, and the impacts on greenhouse energy consumption for heating.

  • 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.

  • 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.
