Greenhouse growers that are new to the industry or those that are interested in brushing up on their knowledge can now sign up for the summer sessions of four self-paced courses in Michigan State University Extension’s Online College of Knowledge greenhouse series: Abiotic Disorders of Greenhouse Crops, Greenhouse and Horticultural LightingBiological Control for Greenhouse Growers and Floriculture Root Zone Management. This award-winning series serves as an excellent resource for greenhouse growers new to the industry or those who want to learn more about other areas of greenhouse crop production or pest management.

These non-credit courses in the series are pre-recorded and registrants have three months to complete the courses: June 1 through Aug. 31, 2020. Students in the course will take a pre-test and a final exam to gauge their learning on the topics. Registrants also can complete the optional self-assessment quizzes to engage with the material throughout the course. Each course is $129.

There are three scholarships for each of the courses for those interested but do not currently have the financial means to take it. The cost of the course will be reduced to $39.99 for scholarship winners. Interested greenhouse growers should see the registration websites below for more details. Registration for all courses ends June 13, 2020. 

Abiotic Disorders of Greenhouse Crops (NEW for summer 2020!)

The brand-new Abiotic Disorders of Greenhouse Crops course is intended for greenhouse and ornamental plant growers who are interested in learning what factors induce or contribute to the onset of abiotic disorders of greenhouse crops. Abiotic plant problems are those that are caused by non-living things, such as cultural or environmental conditions. This course will guide you through the diagnostic process to learn what abiotic factors can cause plant problems causing top growth symptoms (on either foliage, stem, or flower buds) or root symptoms.

MSU Extension partnered with Garrett Owen, former greenhouse outreach specialist at MSU and current assistant extension professor in the Department Horticulture at the University of Kentucky, to develop the course. The course covers an introduction to diagnostics, differentiating biotic and abiotic plant problems, and plant symptoms as a result of the following nutritional, environmental or cultural factors: pH, EC, light intensity, photoperiod, ethylene, chemical phytotoxicity, and herbicide damage.

Biological Control for Greenhouse Growers

MSU Extension partnered with Raymond Cloyd from Kansas State University Extension to offer an online course on biological control pest management. It is intended for greenhouse growers and others interested in learning about the challenges and opportunities associated with a biological control pest management program. The content of the course covers introductory materials to more advanced concepts such as utilizing banker plants.

A total of 330 people have taken the Biological Control of Greenhouse Growers course from 15 countries, including 38 U.S. states, who represented at least 117.3 million square feet of greenhouse production. As a result of the course, 60% incorporated new natural enemies into their biological control program and 80% reported increased crop quality.

Floriculture Root Zone Management

The Floriculture Root Zone Management course is for beginning-level floriculture growers. It covers the fundamental concepts about irrigation water, media and their effects on plant nutrition. The course covers water sources, water quality, water treatment, irrigation methodology and substrate components. The final unit of the course covers the essential elements for plant nutrition, how to select a fertilizer and how to monitor nutrition of greenhouse crops.

One-hundred and thirty-one people have taken the Root Zone Management course from 8 countries and 30 U.S. states, who have represented 18.8 million square feet of greenhouse production. Three-quarters of the participants planned on making changes to their management practices (n=79). Of all of the course participants, 99% reported that they made significant progress on the topics discussed and 97% would recommend the course to another individual (n=65).

Greenhouse and Horticultural Lighting

The Greenhouse and Horticultural Lighting Course is intended for greenhouse and ornamental plant growers and others interested in learning about the fundamental concepts about how plants respond to light quality, quantity and duration. It provides introductory to moderately-challenging content based on experiments performed at MSU. The units in the course cover photoperiod, photoperiodic lighting, light quality, quantity and duration, and factors that should be considered when replacing or installing new lamps.

To date, a total of 274 people have taken this course from 27 countries including 36 U.S. states who represented 42.2 million square feet of greenhouse production. Three-quarters of survey respondents are going to make a crop production change as a result of the course. The topics that were reportedly most helpful were the sections on ‘high-intensity lighting’ and ‘how to estimate daily light integral in your greenhouse.’
