Greenhouse Photoperiodic Lighting Strategies

Part 1: Greenhouse Photoperiodic Lighting Strategies by Chris Currey. Day length (photoperiod) impacts flowering of many greenhouse crops. However, there is no one-daylength fits all approach. In a 3 part series, Drs. Chris Currey of Iowa State University, Roberto Lopez of Michigan State University, and Neil Mattson of Cornell University discuss the photoperiod response groups of common bedding plants, flowering potted plants, vegetables, and herbs. They also discuss strategies for manipulating greenhouse photoperiods, as well as what equipment to use. They tie everything together using case studies on how to use photoperiod to properly schedule bedding and potted flowering plants, and to avoid early flowering or dormancy of ornamental and edible crops.
