CraftGrow — Our Partner Brands

Showcasing the passion and skill of Canada’s craft medical cannabis producers

By building a program that gathers passionate and skilled producers together in one place, Spectrum Therapeutics is able to bring to our patients the best variety of cannabis from some of the most innovative producers in the country. It’s all about two things:


Curating quality. We've partnered with outstanding cannabis producers from across Canada to deliver curated medical cannabis products to our patients.

Providing variety. Every patient is different, and every condition requires a unique approach. CraftGrow provides our customers options when it comes to finding a range of medical cannabis that best addresses their needs.


The small-batch nature of these releases will provide variety to Spectrum medical customers, but because of the smaller scale, may not always be available for reorder.

A B Labs

Artisanal growing techniques and a quality product from Southern Ontario’s Golden Horseshoe


For the team at AB Labs, a premium is placed on people, process, and product quality. At their facility in the heart of Southern Ontario’s Golden Horseshoe, the team starts a new production cycle every 30 days, and uses a traditional flood-and-drain technique to grow short plants in small batches. By accelerating flowering cycles, this process expedites vegetative growth and production time.


Using a cultivation technique popularized in the ’90s, the plants grown at AB Labs are the product of automated simplicity. From office staff to quality-assurance specialists, every member of the team is trained in all aspects of the cultivation process, from propagation to harvest. This practice, centred on people and quality product, helps protect the sanctity of the grow style employed by the entire AB Labs team.


AB Labs’ R&D team is continuing to develop new varieties, while growing out classics, with only the top strains and phenotypes being introduced to the collection over time.

James E. Wagner Cultivation Corporation (JWC)

Clean. Consistent. Aeroponic.


JWC is founded on strong values, having a family history of farming in Southern Ontario dating back to the 1920s. Passion for agriculture and growing everything imaginable is at the root of the JWC family business. James Wagner taught his grandchildren the art of farming as he learned it from his father. The founders of JWC applied these skills to medical cannabis as a collective of patients and growers under the MMAR. In the years that followed, the passion for medical cannabis grew, and the family applied to become a Licensed Producer under the ACMPR (now Cannabis Regulations). JWC was born.


Today, JWC strives to provide patients with clean and consistent medical cannabis, grown in its proprietary aeroponics cultivation platform, GrowthSTORM™. This growing methodology sees the roots of the plants suspended in air, while a nutrient solution is delivered in the form of a fine mist. This ideal environment gives the plant everything it needs, offering increased control over growing conditions and superior plant health and yield.
