Sativa seeds in Canada: common questions
What are sativa-dominant seeds?
Sativa-dominant seeds grow plants with mostly sativa genetics. They tend to grow taller and take longer to flower than indica-dominant strains.
Can I grow sativa strains outdoors in Canada?
Yes, but watch the finish time. Sativas often flower longer, so choose strains that finish before the frost, or an autoflower or fast version.
Do you ship sativa seeds across Canada?
Yes. Quebec Cannabis Seeds ships from Quebec across Canada and to the USA. Orders over $200 ship free, and every order includes free seeds.

Category Intro (Sativa Dominant)
Sativa-dominant cannabis seeds are a go-to option for growers and enthusiasts who enjoy uplifting, mind-forward effects and vibrant terpene profiles. These genetics are often associated with energetic, creative, and daytime-friendly experiences, with aromas that can lean citrusy, fruity, herbal, or sweet. Many sativa-dominant plants develop a taller, more vigorous structure with strong stretch—making them a great fit for outdoor gardens or indoor setups where you can manage height through training. Browse our sativa-dominant selection to find standout genetics based on your grow style, space, and preferred flavors.
About AlphaType Genetics
Who is AlphaType?
AlphaType is a cannabis genetics company that develops F1 hybrid cultivars through a data-driven breeding program. AlphaType maintains Alexandria, a biobank of more than 1,500 coded, open-source cultivars, and uses statistical clustering and cultivar-variance analysis to identify superior genetics before they become new F1 hybrids. AlphaType operates out of Seattle (Washington, USA), Basel (Switzerland) and Bogotá (Colombia). Some of the genetics in this collection were bred specifically for QCS: QCS selects the parent genetics and the traits it is looking for, and AlphaType carries out the breeding to those specifications.

A note on this collection
AlphaType refreshes its own genetics lineup every year, and some of what's listed here was bred to QCS's own specifications rather than pulled straight from AlphaType's general catalog. So some strains may no longer appear (or may never have appeared) in AlphaType's public lineup even though the seeds themselves are unchanged and available here while supplies last.
Frequently Asked Questions about AlphaType
What is AlphaType?
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's own materials describe a scientific, data-driven selection process (the Alexandria biobank and statistical clustering), but we have not found a published certificate of analysis (COA) tied to individual cultivars. We do not present specific 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.
