AlphaType is a cannabis genetics company that develops F1 hybrid cultivars using a biobank-based, data-driven breeding program rather than traditional selection alone.

Where is AlphaType based?

AlphaType lists operations in Seattle, Washington (USA), Basel (Switzerland) and Bogotá, Colombia.

How does AlphaType develop its genetics?

AlphaType maintains a biobank called Alexandria, with data from over 1,500 coded, open-source cultivars, and applies statistical clustering and cultivar-variance analysis to identify superior candidates for its F1 hybrids.

Are the strains on this page AlphaType's current lineup?

Not necessarily. AlphaType changes its own menu of genetics every year, so some strains QCS carries here may no longer be part of AlphaType's current catalog, even though the seeds remain available from QCS while supplies last.

Does AlphaType publish lab testing or COAs for its genetics?

AlphaType tests every production batch for germination and intersex (hermie) rate and reports the results to QCS batch by batch; QCS publishes them on its seed testing page, and every batch published there passed at 98% or 100% germination, with each strain’s own batch results listed. Cannabinoid and terpene certificates of analysis for these batches are in progress and not yet published, so QCS does not present potency numbers as AlphaType-certified lab results.

Where can I see THC/CBD, flowering time and yield for a strain?

Each product listed on this page shows its own typical genetics, cannabinoid range, flowering time and yield, as reported by QCS based on grow data for that specific strain.

Is AlphaType affiliated with Quebec Cannabis Seeds?

No. QCS is an independent, Quebec-based seed bank. AlphaType is one of the outside genetics sources QCS carries seeds from; it is not owned by or formally affiliated with QCS.

Does QCS choose which genetics AlphaType breeds for this collection?

Yes, for some of the strains here. QCS selects the parent genetics and the traits it wants, and AlphaType carries out the breeding to those specifications, rather than QCS simply reselling whatever is on AlphaType's general public menu.
