Fast version cannabis seeds
Photoperiod strains bred to finish sooner, a good fit for short Canadian seasons. Over 20 fast version strains from a Quebec seed bank.

Earlier harvest
Fast version strains are bred to flower faster than the standard version of the same strain.
Made for short seasons
Finishing earlier helps beat the fall frost outdoors.
Photoperiod plants
They flower with the season, but carry a little autoflower genetics, which is why they finish sooner.
Free seeds, every order
Orders over $200 also ship free across Canada and to the USA.

Fast version seeds: common questions
What are fast version seeds?
Fast version seeds are photoperiod cannabis strains bred to flower faster than the standard version of the same strain, so they are ready to harvest earlier.
What is the difference between fast version and autoflower seeds?
Autoflowers flower automatically on their own schedule. Fast version plants are photoperiod: they flower when the days get shorter, but finish sooner than standard strains.
When are fast version seeds ready to harvest outdoors?
Most fast version strains finish in September, and a few reach the first week of October. Timing always depends on the grower and the conditions: experience, weather and stress can all move the harvest date.
Why can stress affect fast version plants more?
Fast versions are made by introducing a little autoflower genetics into a photoperiod strain, which is how they finish earlier. Because they carry the autoflower gene, heat, cold snaps and rough handling can affect them more than a standard photoperiod plant.
Do you ship fast version 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 much faster is a fast version strain
Usually one to two weeks shorter in flower than the photoperiod original, which is often the difference between finishing before the autumn rain and not.
Are fast version seeds the same as autoflowers
No. Fast version plants are still photoperiod, so they flower when the light drops to about 12 hours. They are simply bred to finish that flowering stage sooner. Autoflowers flower on age instead.
Do fast version strains yield less
Not materially. They reach the same kind of structure as the original; they just ripen sooner, which is why they suit a short northern season.
Are fast version seeds good for outdoor growing in Canada
That is exactly what they are for. Finishing one to two weeks earlier moves harvest away from the first hard frost and the wettest part of the autumn.
Do fast version seeds need a different light schedule
No. Treat them like any photoperiod: 18 hours of light in vegetative growth, then 12 to start flowering.
Are fast version strains good for beginners
Yes. A shorter flowering window means less time for something to go wrong, and outdoors it reduces the risk of losing a crop to weather.

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.
