Mark and I interview Eric Rosen who works at Dark Heart Nursery and is a dedicated plant geek or strainiologist. He came from the tech world but always had an eye on the cannabis space desiring to be where his passion was. After bouncing around in cannabis, he locked in with Dark Heart Nursery and as you listen will realize he is at home working there. Eric is a vast treasure trove of info, terms like tissue culture, genetic reset button, pathogens, clones, mothers, pheno types, cannabinoids and all things that drive the genetic feature set for cannabis. Mark dives in here and asks him to explain in more detail about genetic infections hop latent viroid (HpVld) also known as “dudding” which can affect up to 30% of the yield, the potency and quality. We also discuss powdery mildew and other pathogens Dark Heart Nursery is working to identify while providing solutions. This episode is a great one for those wanting to understand the basis point of how breeders around the world utilize landrace strains to provide growers and brands the best cannabis in the world!
