The Best Autoflower Seeds to Grow in Canada

Last updated: 21 October 2023

top autoflowering strains

Buds grown in Canada are considered among the best in the world for a reason. The uniquely lenient attitude to weed and its legality since 2018 have enabled local growers to learn to cultivate even exotic and high-maintenance varieties to perfection. However, if you’re not sure whether your thumb is that green (or if you’re just starting your cannabis-growing career), we present you with a list of dependable and easy-to-grow autoflower seeds that Canada’s climate is ideal for.

Autoflowering seeds and Canada have been joined at the hip from the start. Their history goes back all the way to the 1970s when Canadian growers were cultivating Mexican Rudy, which was the predecessor of Lowryder – the first commercially-available autoflower. The country’s climate isn’t particularly accommodating to this hobby, but for growing autoflowering seeds, Canada is as good a place as any.

What Makes Autoflower Seeds Perfect for Canada?

While the laws differ from province to province, the rule of thumb is that adults can grow up to four cannabis plants with few legal repercussions or none at all. The climate in Canada, on the other hand, is much more restrictive than the legislation. Relatively short summers and cool weather in fall make it impossible to grow many top-shelf photoperiod varieties outdoors. This is where autoflowering seeds come as a blessing for Canada’s weed growers.

The extremely short maturation period of autoflowers allows you to have at least one harvest outdoors – and in some cases, two consecutive harvests – if you choose the fastest genetics and live in a warmer place in Canada or use a greenhouse. Thanks to the presence of Ruderalis genes, autoflowers aren’t only fast but also uncommonly resistant to elements, be they cold, heat, constant rain, or drought. You’re also less likely to face the issue of mold because you can harvest the buds before the weather gets cool and rainy.

And the best part of it all is that modern autoflowers produce the same premium smoke as traditional strains. Think of any famous variety – chances are that there’s an autoflowering version available on the market.

Autoflowering Seeds Canada’s Growers Should Consider

When compiling the list below, we tried to be as inclusive as possible, not forgetting dwarf autoflower seeds for those provinces in Canada where you still need to be discreet, high-CBD autoflower seeds for Canada’s medical growers, and, of course, everybody’s favorites – XXL autoflower seeds for bumper harvests, even in the less-than-perfect climate that Canada offers.

For those of you who want to conceal their cannabis patch among other crops, dwarf autoflower seeds like Strawberry Pie Auto are close to perfect. Usually measuring just 2 feet and rarely growing to more than 3’4’’, this dominant Indica is high-yielding nevertheless. Her large, rock-hard buds are strikingly beautiful with their pink colors blushing from under a thick layer of frost. The attraction doesn’t stop there, as the sweet smell and taste of berries and cookie dough make her one of the most delicious autos. Beware of this honeytrap’s charms, though – 26% THC means powerful, almost narcotic relaxation that not everyone can handle.

And the buds aren’t just plentiful but super-potent as well – with 25% THC and more than 2% CBD, they produce giddy euphoria in the head and strong but mellow relaxation in the body.
