Doctor’s Choice is a Canadian seed company that produces and distributes premium Cannabis seeds. Founded by Sasha Przytyk, also known as the Joint Doctor, we take pride in our unique legacy as industry pioneers. By introducing the world to Lowryder, Sasha Joint Doctor kicked off a new era of home-growing.
Doctor’s Choice is the birthplace of the world’s first autoflowering cannabis strain — Lowryder. What started as one man’s curiosity became a global revolution in breeding.
Autoflowers changed the game forever: faster growth cycles, resilience to colder climates, and effortless cultivation for growers of all levels.
Today, we continue to refine and expand this legacy — crafting genetics that blend speed, stability, and quality like no other.
