Lighting Part 1: Introduction and Benefits of Supplemental Lighting

Part 1 of a 3 Part Series. Dr. Roberto Lopez of Purdue University is the presenter. Greenhouse supplemental lighting is important to maintain crop growth, quality and yield during winter months and cloudy days. As an additional production cost it is important to know plant response to supplemental light and when you are providing too much light that the plant cannot utilize. Attendees will learn about different lighting strategies (time clock, light threshold, or lighting to a daily light integral target) and the costs and benefits of each strategy. Attendees will also learn how to properly maintain and clean supplemental lights, to calculate how many lamps are needed and the hours the lamps need to be on to reach a light target, and how to calculate the energy usage and costs of these lamps. Neil, Josh and Roberto will also present recent research findings comparing plant responses and cost of supplemental light using high pressure sodium (HPS) and light-emitting diodes (LEDs).
