Best-selling cannabis seeds: common questions
What are your best-selling cannabis seeds?
The strains on this page are ranked by real orders. Long-standing leaders include Quebec Gold 2.0, Gorilla Glue and Quebec Blue, alongside classics like White Widow, AK-47 and Jack Herer.
How is this list ranked?
By how much each strain has actually sold through our store — not by editors. It reflects what growers across Canada and the USA buy most.
How often does the list update?
We refresh it periodically so it keeps matching real sales. The leaders change slowly, while newer strains climb over time.
Are best-sellers a good choice for beginners?
Often, yes — strains become best-sellers partly because they are reliable and forgiving to grow. Each strain's page notes how demanding it is, and our beginner category is a gentle place to start.
Can I find these strains in other categories?
Yes. Every strain here also lives in its own type category — feminized, autoflower, CBD and so on — at the same price and with the same free seeds.
Do you ship across Canada and the USA?
Yes. Quebec Cannabis Seeds ships from Quebec across Canada and to the USA. Orders over $200 ship free, and every order includes free seeds.

Our best-selling cannabis seeds in Canada
This page ranks the cannabis seeds that sell the most through our Quebec store, so it is a reliable shortlist of what growers actually choose. Strains like Quebec Gold 2.0, Gorilla Glue and Quebec Blue have led our orders for a long time, with classics such as White Widow, AK-47, Jack Herer and Blueberry close behind — a mix of feminized photoperiod strains and autoflowers.
Every strain shown here is also listed in its regular category, at the same price, in the same pack sizes, with the same free seeds on every order. A strain earns its place here by selling well, not by being promoted. Each product page carries the detail you need to choose well — type, expected flowering time, indoor and outdoor yield, and grower reviews.
Popularity is a good starting point, but not the only thing that matters: the right seed also depends on your space, your experience and the kind of effect you are after. When you are ready to go deeper, follow any strain into its type category, or use the links below to jump straight to feminized, autoflower or QCS-bred seeds.
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 tests every production batch for germination and intersex (hermie) rate and reports the results to QCS batch by batch. We publish them on our seed testing page: every batch published on that page passed at 98% or 100% germination, and each strain’s own batch results are listed there. Cannabinoid and terpene certificates of analysis (COAs) for these batches are in progress and not yet published, so we do 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.
