Online training opportunities for greenhouse and nursery growers: Part 1

Greenhouse and nursery growers can beat the heat by exploring numerous online video training opportunities to brush up their skills and knowledge during the off season.

July 2016 has brought temperatures in the 90s and 100s across the United States. Greenhouse growers that want to beat the heat can do so by exploring numerous online training materials this summer. In Part 1 of this article, I will review training materials through Electronic Grower Resources Online (e-GRO). Michigan State University Extension recommends growers subscribe to the many resources e-GRO offers: alerts (articles), videos, webinars, e-books and research reports from the e-GRO team.

Specifically, I would like to make growers aware of the 57 free videos available through e-GRO University and those available through e-GRO on YouTube. These videos are categorized by greenhouse management, growth management, nutrient management, insects and mites, and diseases. Unless otherwise noted, all of the following videos can be found at e-GRO University.
