Atlas Seeds

Atlas Seed Cannabis Seeds in Canada

Frequently Asked Questions

Does Montreal Cannabis Seeds breed Atlas Seed strains? No. We are a seed bank, not a breeder. Atlas Seed is the breeder, and every Atlas Seed strain page names it.

Where do the THC, flowering and yield figures for Atlas Seed strains come from? From Atlas Seed’s own published data. When Atlas Seed has not published a figure, the page says “Not specified by the breeder” instead of an estimate.

Is a Atlas Seed strain the same as another breeder’s strain with the same name? No. Strains that share a name, such as White Widow or Cheese, are different selections from different breeders, and their figures should not be mixed.

Are Atlas Seed seeds covered by your germination guarantee? Yes. Our germination guarantee covers 80% germination within 90 days of purchase when our instructions are followed. We replace seeds that fall short.

Do you ship Atlas Seed seeds across Canada? Yes. Orders ship from within Canada in plain, unmarked packaging.

Guides for Canadian Growers

Looking for seeds that suit your space and your season? These guides answer the questions growers ask most:

• Cannabis seeds for beginners: how to choose your first seeds.
• Your first cannabis garden: a step-by-step beginner guide.
• Growing cannabis in tight spaces: tents, LEDs and micro-grows for apartments and balconies.
• Growing cannabis outdoors: planting, care and harvest.

Autoflower and fast-version seeds generally finish sooner than standard photoperiod seeds, which can help in short Canadian seasons. Results depend on genetics, climate and care. Each product page lists typical flowering time, height and yield.
