Information about Mr. Nice

Mr. Nice Seeds

Mr Nice Seed Bank is one of the most respected seed banks in the world. Its founders are among the pioneers of cannabis breeding. You can find all their knowledge and passion in both the potent old school strains and the newly awarded hybrids.

In April 2016 Howard Marks, alias Mr. Nice, left this world. He was one of the first pioneers of today’s “regulated” cannabis business, and he left us with a rich inheritance of unique cannabis strains. After being imprisoned in the United States for smuggling, he founded in 1990 the Mr. Nice Seed Bank together with other two notorious breeders, Scott Blakey “Shantibaba” and Neville Schoenmaker. All cannabis strains bred by Mr Nice Seed Bank actually incorporate the talents and the huge wealth of experience of their breeders, resulting in a large amount of international awards.

Today, Mr. Nice Seed Bank still owns the original genetics which were saved from the Dutch authorities’ repression in 1995, and then saved again from the shutdown forced by a Swiss Prosecutor in 2003. Thanks to the actual owner Scott Blakey, the spirit and the smiles of his friend Mr. Nice still live today in both the old school and the new descendant strains. Preserving genetics and biodiversity has always been Shantibaba’s and Mr. Nice Seeds Bank’s philosophy, reflected in today’s precious cannabis seeds such as Lights 5, Super Silver Haze, White Widow, White Rhino and White Shark, to name a few.

Mr Nice Seed Bank produces all its seeds in its own controlled breeding research laboratories and has always interacted with the growers who work with its strains to help getting the most of them and increase the shared knowledge. Shantibaba is also committed in spreading information about medical cannabis genetics and cultivation techniques. His company is today involved in the CBD Crew project for the research on high-cannabidiol strains. Zamnesia offers you some excellent strains from the Mr. Nice Seed Bank which will all make you smile.

Critical Mass (Mr. Nice)


  • 2008, Copa Highlife BCN 2008 - Yervagüena for Critical Mass
  • 2008, Highlife Planta del año 2008 - Mr Nice Seeds for Critical Mass
  • 2008, Copa de la Marihuana de Madrid, 2nd prize
  • 2007, Marijo Taxpalketa, 2nd prize outdoor
  • 2006, Copa de la Marihuana de Madrid, 3rd prize

A robust cross between an ancient Afghani and the notorious Skunk #1 gave birth to an excellent version of an old breed. This is a high yield strain for commercial farmers and outdoor crops. The heavy Afghani pedigree makes you expect a yield indoors around 650-750g/m² with a flowering time of 45/55 days. Outdoors you can harvest 500-600g of heavy flowers per plant. Critical Mass needs you to keep the humidity under control because her exceptionally compact flowers can attract mould. With this precaution she will greatly reward both the inexperienced and the professional grower.
