I don't know if it was the same video, but he was talking about cleaning up cookiefams genetics, sherbinski was who he mentioned I think.
Perhaps the old story, "my cut has a virus, should I burn it?" Will be easy to answer soon.
Kevin's videos are an amazing resource. Ten years ago I visited his shop and he was really helpful and answered all my questions and his flower room was just amazing. I've never seen anything like it in person again. (Chaco's was close.)
They had the best prices in the state for flower at their dispensary too.
Very compassionate dude.
Seems like a real down to earth and most knowledgeable and respectful dude. In one vid he mentions giving away a bunch of things to CBD for free before regulations forced them to stop.
He had the SFV listed on the tissue culture info last time I checked.
