Mr. Nice Seeds

**Mr. Nice Seeds** is a legendary cannabis seed bank founded in 1998 by Howard Marks (Mr. Nice) and renowned breeders Shantibaba and Nevil Schoenmakers. The company was formed after Shantibaba and Nevil left the Sensi Seeds breeding project. It is most famous for preserving and continuing the original, world-changing genetic lines developed in the 1980s and 1990s, particularly those from the **Greenhouse Seed Company** and **The Seed Bank**. **Key Contributions & Legacy:** * **Genetic Preservation:** Mr. Nice Seeds is the primary guardian of the original, un-hybridized **"Haze"** genetics (e.g., Neville's Haze, Super Silver Haze) and the foundational **Skunk #1** and **Northern Lights** lines. Their **"Black Label"** series represents these historic IBLs (Inbred Lines). * **Iconic Strains:** They are the original creators of some of the most awarded and sought-after strains in history, including **Critical Mass**, **Medicine Man** (White Rhino), **Shark Shock**, and the multiple Cannabis Cup-winning **Super Silver Haze** and **Neville's Haze**. * **Breeding Philosophy:** The focus is on **stability**, **potency**, and **authenticity**. They emphasize open-pollination of large populations to maintain genetic diversity and avoid the "clone-only" bottleneck, ensuring their legendary genetics remain available to all growers as true breeding seed lines. * **Howard Marks:** The late Howard Marks, a famous author and former cannabis smuggler, lent his name, philosophy, and charismatic advocacy to the brand, connecting the cannabis culture of the 70s/80s with the modern seed industry. Today, under the guidance of Shantibaba, Mr. Nice Seeds continues its work from Switzerland and Spain, focusing on medical applications and preserving its unparalleled genetic library for future generations.
