MSU Offers New Greenhouse Lighting Online Course For Growers
Michigan State University Extension is now offering a non-credit, pre-recorded online course on greenhouse and horticultural lighting. The lighting course is intended for greenhouse and ornamental plant growers and others interested learning about the fundamental concepts about how plants respond to light quality, quantity and in duration. It provides introductory to moderately-challenging content primarily based on experiments performed at Michigan State and Purdue Universities. This is the second course in the College of Knowledge Online series offered on the national Extension website. The first course was Floriculture Root Zone Management, also available online. What Growers Will Learn From Taking This Course The 3-hours of pre-recorded lecture and video demonstrations are divided into seven units. The first and second units cover the properties of light and its importance for plant growth and development. The third unit discusses how light quality influences stem extension and flowering. The fourth unit of the course teaches […]

Customizing Crop Foliage Color With LEDs: Ornamental Crops
Do you find that your purple fountain grass (Pennisetum setaceum ‘Rubrum’) crop is often green to light purple? What if we told you there is a quick solution to enhance and darken the foliage of purple fountain grass or other floriculture crops? In this second article of a four-part series highlighting the multiple uses of high-intensity light-emitting diodes (LEDs), we will discuss our research methodology and findings for enhancing the foliage color of ornamental crops with end-of-production (EOP) supplemental lighting (SL) in the greenhouse. Many ornamental crops that greenhouse and nursery growers produce vary in size, shape and color. These variables are often influenced by the growing environment. For example, leaf color (intensity, distribution or both) of ornamental crops such as purple fountain grass is a key component that often influences the consumer’s perception and ultimately an impulse purchase. The red or purple pigmentation of purple fountain grass leaves is […]

The Basics & Beyond: Understanding The Differences Between Photoperiodic And Supplemental Lighting
As I talk to growers around the country, I often find that there is confusion between (1) photoperiodic lighting used to create a long day for flower induction of long-day plants and (2) supplemental lighting used to increase the total quantity of photosynthetic light received over the course of the day, which is referred to as daily light integral (DLI) in the greenhouse. For more information on DLI, please visit http://bit.ly/11x79eK To add to the confusion, supplemental lighting is sometimes referred to as photosynthetic or assimilation lighting. In this article, I will attempt to clarify the differences to assist you in selecting the appropriate lighting strategy for your greenhouse crops. Understanding Photoperiodic Lighting The number of hours of light in a 24-hour period (photoperiod) controls flowering of both short-day and long-day crops. It is actually the uninterrupted period of darkness that controls flowering responses. Long-day plants are those that only flower […]

Don’t Let Your New Year’s Resolutions Fade …
Stuff got real in 2017, and it caused many of us to stop and reflect on the current state of the world, and how we can impact change — or at least improve our own situations. Life is too short, and we work too hard, to not use the annual renewal as an opportunity to take stock of our own personal lives, businesses, and careers, and make the necessary adjustments that will allow us to work smarter and live better. Even if you have already given up on your resolutions, perhaps you can think of January as a trial month and make February the month when you really get to work on your goals. And while I know it’s a difficult month to start on some of these changes, since you’re already immersed in the busy spring season, I promise that if you take some time to evaluate your reality […]
