Cannabis seeds in Canada: common questions
What kinds of cannabis seeds do you sell?
Feminized, autoflower, CBD, fast version and regular seeds, plus mixed packs and bulk packs. Most packs contain 5 seeds.
Which seeds should I start with?
For a first grow, look at our seeds for beginners: forgiving strains that are easier to manage from seed to harvest. Autoflowers are a popular first choice.
Do you ship cannabis 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.
How long do cannabis seeds stay viable
Several years when stored cool, dark and dry. An airtight container in the fridge is the usual method. Germination rates fall slowly rather than suddenly, so older seeds often still sprout, just less reliably.
What is the difference between feminized and regular seeds
Feminized seeds are bred to produce flowering female plants, so there are no males to identify and remove. Regular seeds produce roughly half males. Almost everything we sell is feminized.
What is the difference between autoflower and photoperiod seeds
Autoflowers begin flowering on age, usually 3 to 5 weeks from seed, under any light schedule. Photoperiod plants flower when daylight drops to about 12 hours, which outdoors means late summer.
How many seeds should a first-time grower buy
Two or three plants is a sensible first attempt: enough that one failure is not the whole crop, few enough to watch properly. Canada permits four plants per household, and Quebec prohibits home cultivation entirely.
Do you guarantee germination
Yes. If fewer than 80% of your seeds germinate we send replacements, and we guarantee delivery of every order.
How are orders packaged
In plain, unbranded packaging with nothing on the outside indicating the contents, and no signature is required.
How long does delivery take
Canada is 3 to 7 days by standard post or 2 to 3 days by Express. The USA is 1 to 2 business days by Express. Orders ship from Quebec, usually the same day or within 24 hours of payment, Monday to Friday. Shipping is free over $200.

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.
