We also discuss how different varieties affect us, his journey from prison to AG Seed Co., the incredible people he met along the way, the problem with modern polyhybrid genetics, hype phenos, autoflowers, and what all of it means for preserving the plant long-term

Cannabinoid Hyperemesis Syndrome C.H.S. is B.S. Modern medicine often moves quickly. A clinical observation becomes a hypothesis, a hypothesis becomes a paper, and before long that paper becomes a diagnostic reflex. But when the foundational evidence is thin, repetition can substitute for proof, and speculation can harden into certainty.
