Lowtemp x Bubbleman

Hash Masters University Feat. The Real Cannabis Chris

Whether you're just starting out or have years of experience under your belt, our classes offer invaluable insights, techniques, and expertise from the best solventless hash makers in the world.

This month’s class is hosted by the Bubbleman
Marcus Richardson, better known as The Bubbleman, is one of the most influential figures in modern hash making. A cannabis pioneer since the early 1990s, he is best known as the inventor of Bubble Bags—one of the first widely adopted systems for ice water extraction, helping popularize solventless hash production worldwide.

Beyond his products, Marcus has spent decades educating the global cannabis community. He is the founder of Hash Church, a long-running weekly series that has become a hub for hashmakers to share knowledge, stories, and techniques.
