Growing Truffles commercially (good intro video)

I attended this lecture about the commercial truffle industry.
Good introduction to the various culinary truffles, false truffles, which tree species are good to grow truffles under, basic cultivation techniques, etc.

Also, there's an organization called North American truffle Growers Association if you wanna really get into it! (https://trufflegrowers.com/)

And I thought truffles were just an Italian thing! Did not know they were in the USA. And...it is possible to grow them commercially? Thanks for putting this on the radar--I hope it was a great seminar.
