About the Course:

This 5-week course is designed for farmers who want to improve their understanding of why you might want to grow hemp, key considerations involved with this particular crop, and what we know about this plant and what it might do for your customers that use it.

The course will involve your watching three to six short videos each week (approximately 90 minutes per week, and attending a one-hour synchronous zoom meeting with other class participants, UVM staff, and me). Each video has embedded questions that will be asked to answer so that I can know each participant has watched and completed each module.  If you are a crop advisor, a credit will be offered for completing each module and another for each synchronous session for a total of 10 CCA continuing education units.
