Best and most popular cannabis seeds: common questions
What are the best cannabis seeds to buy in Canada?
There is no single best seed — it depends on your space, your experience, and whether you want feminized or autoflower plants. This page gathers the strains we currently recommend most, so it is a good shortlist to start from before you narrow down by type.
What are your most popular strains?
The strains shown on this page are the ones we are featuring right now, chosen from across the catalogue. The selection changes through the year as interest shifts and as we add new genetics.
How often does the featured list change?
From time to time, so the strains here will change through the year. It is worth checking back for new additions and seasonal picks.
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 — so you can reach it either way, at the same price and with the same free seeds.
Are these strains good for beginners?
Some are very forgiving and some are more demanding. Each strain's page notes how easy it is to grow. If it is your first grow, our beginner category is a gentler place to start.
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.

The best of our Quebec cannabis seeds, in one place
This page brings together the cannabis seeds we are recommending most right now, drawn from across our Quebec catalogue. If you are shopping for the best cannabis seeds in Canada and do not want to scroll through hundreds of strains, it is the shortest route to a strong shortlist — popular feminized photoperiod strains, autoflowers, CBD genetics and our own QCS-bred lines, side by side.
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. Featuring a strain simply brings it to the front of the shop; it does not change anything about the seeds. Each product page carries the detail you need to choose well — type, expected flowering time, indoor and outdoor yield, and grower reviews where we have them.
Because the selection is hand-picked and refreshed through the year, it is a good page to bookmark. When you are ready to go deeper, follow any strain into its type category to see everything of the same kind, 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.
