Quebec Cannabis Seeds (QCS) is a Canadian seed bank that has supplied cannabis seeds to home growers since 2015. We carry more than 300 strains of feminized, autoflower and CBD marijuana seeds, and many are bred and selected in Quebec for northern outdoor conditions: short summers, cool nights and high humidity.
Every order ships from our own location in Quebec to Montreal, Quebec City, the rest of Canada and the USA, in discreet packaging. Whether you call them cannabis seeds, marijuana seeds, weed seeds or pot seeds, you are buying directly from the breeder.
Common questions
Where does Quebec Cannabis Seeds ship?
We ship cannabis seeds across Canada and to the USA. Orders over $200 ship free.
Do I get free seeds with my order?
Yes. We add free cannabis seeds to every order.
Which seeds are best for growing outdoors in Canada?
Choose by harvest month. Most autoflowers finish in August, early photoperiod strains finish in September, and longer-season strains finish in October. Our outdoor category lists strains selected for short summers and cool nights.
What is the difference between feminized and autoflower seeds?
Feminized seeds are bred to produce female plants. Autoflower seeds flower automatically, without a change in the light schedule.

Most packs contain 5 seeds. Mixed packs contain 8.
