  • Water vapor-pressure deficit

    Published on December 6, 2021
    The driving force for plant water loss is best described by the vapor-pressure deficit (VPD). This article discusses VPD classifications and what values are suitable during crop production.

  • The indoor lighting guide: Growing seedlings under LEDs

    Published on July 1, 2021
    This 24-page guide provides research-based information about producing young plants indoors (without sunlight) under LEDs. Developed in partnership with GrowerTalks magazine.

  • Red and Blue Radiation: Explore the Efficacy of LED Supplemental Lighting for High-Wire Vegetable Transplants

    Published on August 10, 2020
    High-quality vegetable transplants for high-wire production require a minimum DLI of 13 mol or greater. Therefore, supplemental lighting is commonly used to increase the DLI during light limited times of the year. Can LEDs be utilized?

  • Indoor propagation

    Published on July 14, 2020
    High-value crops can be propagated indoors, inside refrigerated growth rooms and without sunlight. This article briefly lists some of the important considerations for an indoor propagation facility.

  • Propagation pointers

    Published on November 14, 2019
    Propagating ornamental crops is one of the most challenging aspects of production, yet an increasing number of greenhouse growers are doing it themselves. This article provides a brief overview of tips for successful propagation.

  • Monitoring Growth of Bedding Plant Seedlings Using Images

    Published on October 13, 2019
    Monitoring growth and development is an important practice to ensure that crops remain on schedule and to rectify issues early in production. New imaging technology provides some of the most efficient, non-destructive, and accurate means to monitor growth.
