Welcome to NorCal Seeds and Genetics or NSG for short. With over 50 years of experience and expertise, NSG is the leader in the field of modern cannabis breeding, cloning and stabilized seed production.

NSG is a privately owned Northern California based genetic consulting company specializing in breeding cannabis and bringing commercial grade cannabis seed and genetic IP to the world market. 

NSG believes genetics and good breeding practices are key to the future of cannabis and hemp cultivation on a commercial level and that there is nothing more important or as valuable as the reproduction of genetic material and the IP it creates.

NSG curates one of the largest cannabis seed and pollen banks in the world.  NSG has been traveling the world studying how cannabis uniquely differentiates itself by means of phenotyping by context of climate zone.  Seeds from all varieties and from all climate zones around the world have been gathered over the decades to contribute to our seed bank library. 

There are many seed companies for you to choose from these days, so we truly appreciate your interest in what we can do for you.  

NSG has been the ONLY cannabis company that has and can produce and bring to market a stable strain for a client that is 100% designed by the client to meet their specific needs. The end result is a desired cultivar chemotype expressing every trait the client is looking for when they can not find what they need from an open source method.  

NSG was the first company in the world to offer clients the ability to design a cultivar to their exact specifications for patenting. 

It is vitally important that when a client is looking to create their “BRAND” that their cultivar be unique and distinguishable from all other cultivars. Along with providing our clients with these unique cultivars, NSG also provides complete SOP’s and technical support to grow every cultivar consistently, guaranteed.  

You will be happy to know that whether you choose from one of our heirloom cultivars or one that we design for you; NorCal Seeds and Genetics rigorously tests for contaminants, pathogens, recessive DNA and RNA traits. NSG also provides real time COA data percentages of terpene and cannabinoid profiles of every cultivar produced.


NSG offers the finest quality unique; stabilized seed stock, pollen, genetic material, clones and plants for sale and licensing to craft cultivators as well as large commercial growers who wish to develop new cannabis and hemp cultivars specifically designed to meet their needs for commercial and patented usage.

NSG is proud at what has been achieved and has the scientific data to show for it. 

Highlights include:

  • Royal Jack, the strongest purple cannabis cultivar in the world developed by NSG. 
  • The first all deep dark red cannabis plant (anthocyanidin group of flavonoids) –         NSG’s Cherry Bomb Cultivar.
  • Wine Country Cannabis Cultivars that mimic the smell, taste and color of different wine varieties.  Cabernet Kush, Merlot Kush, Sonoma Syrah, Cuvee’, Pink Champagne, Zinfandel and more created for Wine Country Cannabis Company.
  • Skunk weed that is stinkier than ever!  NSG has designed a new Super Stinky Skunk Cultivar that is stronger and stinkier than the original! 

Whatever your cannabis cultivar needs may be, NSG can make it a reality for you.  Perhaps you are looking for a cultivar that produces a larger yield of flower or you are looking for a specific color or a trait bred into or taken out of a cultivar, NSG is your answer. 

NSG can produce cultivars with chemical and physical profiles specific to the needs of our clients such as percentages of sugars, lipids, waxes or terpene profiles along with high or low percentages of THC and other (un)desired cannabinoids.

Thank you for choosing NorCal Seeds and Genetics!

Partnerships and Projects:

NorCal Seeds and Genetics partnered with NorCal Seed Company and Steep Hill Labs of Berkeley, California in late 2017 and began its first RNA sequencing project collaboration with The University of Colorado Boulder.

NorCal Seeds and Genetics and Steep Hill Labs then started their next collaboration called, “Project Jenny” in Spring of 2018 to examine NSG’s vast seed and pollen bank from around the world in the field. The field study antiquated vast amounts of genetic, chemical and observational data on each individual strain from seed to harvest and curing to consumption.

Project Jenny was a windfall of valuable information for both NSG and Steep Hill Labs.  To date, NSG has extensively studied over a hundred cultivars and scheduled to continue studying hundreds more over the next few years. 

This data from Project Jenny has filled in blanks and provided conclusive answers about how we perceived and produced cannabis both privately and commercially. Project Jenny has forever change how we look at cannabis.

NorCal Seeds and Genetics partners with Sagarmatha Seeds.                               

NSG formed a limited partnership with Sagarmatha Seeds from Amsterdam in January of 2019. Genetic material has been traded and bred both in the United States and in The Netherlands. NSG provides all of the varieties that Sagarmatha Seeds once sold including Alaska Thunder Fuck.

NSG is honored to have an old schooler like Sagarmatha Seeds to breed with and distribute in the United States while strategically entering the European market.

May of 2019:  RNA Sequencing Project – Landraces: Analyzed and Completed

Scope of Project:

1. Chemical Profiling of Sequenced Strains
2. Quality Check & Transcriptome Statistics
3. Identification of Cannabinoid Synthases
4. Identification of Terpenoid Synthases

2019 Operation Jenny: Study the effects of extreme cold on cultivation and how pectin production vs water content protects the plant while in the vegetation state. Study complete.

2019  Herer Group Project: Developed Herer “Expressions” cultivars for the Herer Group 

2020  In House R & D Bloom Study with Herer Expressions.

2021  Study on cloning. Status is on going.

2021  Field Study & Data Testing with Herer Expressions

2022  Seed Reclamation Project
