The Story of Mr. Nice Seed Bank: A Legacy of Cannabis and Adventure


Mr. Nice Seed Bank is not just another name in the cannabis industry; it’s a brand rooted in adventure, notorious characters, and an unwavering passion for breeding top-quality marijuana strains. With a colorful history tied to the late Howard Marks — who was not only a legend in the cannabis community but also an infamous figure in international smuggling—the seed bank has carved out a unique legacy in the world of cannabis breeding. Partnered with the exceptional breeding work of Shantibaba (Scott Blakey), Mr. Nice Seed Bank remains a significant source of old school genetics.


From Oxford University to International Smuggler


Born in 1945 in Wales, Howard Marks led an extraordinary life, becoming one of the most famous cannabis smugglers of his time. His journey began at Oxford University, where he initially pursued a career in physics but eventually ventured into more unconventional activities. By the 1970s, he had turned to smuggling large quantities of hashish and marijuana.

Howard Marks was known for his intelligence, charm, and wit. For years, he lived a double life under multiple identities (43 aliases, to be exact) to evade law enforcement around the world. His smuggling operations mainly focused on transporting large quantities of hashish from countries like Pakistan and Afghanistan to Europe and the United States. He claimed to have been associated with organizations like the IRA, MI6, and even the Mafia, making him something of a legend in underground circles.

Marks was arrested in 1988 and sentenced to 25 years in prison but served only seven years before his release. Afterward, he redirected his talents towards writing and published his autobiography Mr. Nice, which became a cult classic. In it he details his life of crime, evading the law, and his love for cannabis. The book later inspired a movie starring Rhys Ifans as Marks.



The Beginnings of Mr. Nice Seed Bank


In 1999, Howard Marks teamed up with Shantibaba, a well-known cannabis breeder, to launch the Mr. Nice Seed Bank. The name "Mr. Nice" was derived from Marks’ infamous alias. While he was the face of the operation, it was Shantibaba’s expertise in cannabis breeding that propelled the seed bank to global success.

Scott Blakey, better known as Shantibaba, is among the most respected cannabis breeders in the industry. Before joining Mr. Nice, Shantibaba had already solidified his reputation while working with the Green House Seed Company, where he created some of the most iconic strains of the 90s, such as White Widow, Super Silver Haze, and Northern Lights #5 x Haze

When Shantibaba left Green House to join forces with Howard Marks, he brought these genetics with him. His focus was on producing high-quality strains with stable genetics. Mr. Nice Seed Bank quickly gained recognition for the consistent quality of its seeds.

We met Howard Marks a few times through a mutual friend. He loved living in Spain and was instrumental in attracting breeders around Europe to the sunny south. We don't recall ever seeing him without a joint in his hand, except when eating! 




Iconic Strains of Mr. Nice Seed Bank


Over the years, Mr. Nice Seed Bank has produced a number of strains that have achieved legendary status. In a world where most breeders prioritize producing feminized seeds, Shantibaba stands out for his dedication to preserving the genetics of cannabis by producing regular seeds. He is one of the few who still values this important aspect of cannabis cultivation.
