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.

QCS Early Outdoor Canadian Strains

At Quebec Cannabis Seeds (QCS), we focus on one clear niche: being the Canadian hobbyist’s outdoor and first-grow seed bank. Our goal is simple—help home growers across Canada choose genetics that fit real outdoor conditions, not idealized grow-room environments. That’s exactly why our Early Outdoor Canadian Strains category exists.

This collection is built for growers in Quebec, Ontario, and the Maritimes, where shorter summers, cooler nights, early fall rain, and seasonal humidity can make timing everything. We select early-finishing and fast version marijuana seeds that are better suited to northern outdoor growing, helping hobby growers reduce end-of-season risk and improve their chances of a successful harvest.

Instead of trying to compete as a generalist seed bank, QCS focuses on practical outdoor performance for first-time and home growers. Our product naming, strain categories, and messaging are designed to make it easier to identify the right seeds for your climate and skill level. If you’re growing outdoors in eastern Canada and want dependable, easier-to-manage genetics, this is the category built for you.
