Sasha Przytyk (aka the Joint Doctor) has had a remarkable career, with extensive experience in both medicinal Cannabis and industrial hemp cultivation. He is currently the in-house breeder at Neptune of the North Ltd.

Growing up on an organic farm where Cannabis was a central, though illicit crop, Sasha sought ways to build a career in the budding “legal” sector. Sasha and his father Jerzy became the first recipients of an Industrial Hemp Research license in Québec, back in the late ’90s. Under the auspices of Gen-X Research, now relocating to Saskatchewan, he distributed the first short-season oilseed hemp variety to farmers on the prairies. All the while, he pursued a passion for collecting seed and breeding novel plants, with a special focus on small, fast strains.

Beginning in the early 2000s, Sasha began to establish “The Joint Doctor” and “High-Bred Seeds” as world-renowned seed brands. Through the revolutionary and enormously succesful strain “Lowryder,” the Joint Doctor pioneered the concept of autoflowering Cannabis worldwide. Lowryder is often recognized as the first 100% autoflowering variety and the Joint Doctor has often been dubbed the “Father of Autoflowering.” Widely adopted by seed companies today, autoflowering strains now represent a significant portion of the seed market.

Sasha has a frequent guest speaker and delegate at international Cannabis conferences and symposiums. He is also an accomplished publisher in the field, writing numerous articles on hemp and its cultivation. He has worked alongside several seed companies and cultivation startups, both in the medicinal and industrial hemp sector. Over the years, he has worked on several breeding projects for major seedbanks including Dutch Passion, and his own Doctor’s Choice seedbank based in Czechia.
