Autoflower Seeds

Autoflower Seeds Canada | Super AutoFlowers

Autoflower seeds grow into cannabis plants that start flowering on their own, based on age rather than changes in light. Most varieties go from seed to harvest in about [8 to 12] weeks, making them one of the fastest and simplest options for home growers. Our autoflowering seeds are backed by our [100% germination guarantee] and shipped across Canada and the United States. Every autoflower we sell is bred in-house by Super Auto Flowers.

What are autoflowering seeds?

Most cannabis plants are photoperiod plants, meaning they only begin flowering when the days get shorter. Autoflowering plants get their trait from Cannabis ruderalis, a variety that adapted to northern regions with short summers. Breeders cross ruderalis with other cannabis genetics to create plants that flower automatically after a few weeks of growth, no matter how many hours of light they receive.

Why growers choose auto flower seeds

Autoflowers finish quickly, often in about two to three months from seed. They usually stay compact, commonly around [60 to 120 cm], which suits tents, balconies, and small spaces. Indoors, they don't need a change in light schedule to start flowering, so many growers keep lights on a steady [18 or 20] hours a day from start to finish. Their speed also means some outdoor growers can fit more than one harvest into a single season.

Autoflower seeds for Canadian growing seasons

Canada's outdoor season is short, and early fall frost can end it before photoperiod plants finish. Because autoflowers run on their own timeline, they can be planted in late spring and harvested in summer, well before cold weather arrives in most regions. This makes them a practical choice for outdoor growers across much of Canada and the northern United States. Because we breed our own autoflowers, our strains are developed and tested in Canadian conditions.

Frequently asked questions

How long do autoflowers take to grow?
Most autoflowers take about 7 to 12 weeks from seed to harvest, depending on the strain and growing conditions. Each product page lists the expected time for that variety.

Are autoflower seeds feminized?
Most autoflower seeds sold today are feminized, meaning they grow into female plants. All of your autoflowers are feminized. Learn more on our [Feminized Cannabis Seeds] page.

What light schedule do autoflowers need indoors?
Autoflowers don't need a change in light to begin flowering. Many indoor growers use 18 hours of light and 6 hours of darkness, or 20 and 4, for the whole grow.

Can autoflowers be grown outdoors in Canada?
Yes, as long as home cultivation is allowed in your province. Their short life cycle helps them finish before fall frost in most regions. See our [Legal Info] page for provincial rules.

What's the difference between autoflower and photoperiod seeds?
Autoflowers flower automatically based on age and finish faster. Photoperiod plants flower when the light schedule changes, take longer, and often grow larger. Growers who want speed and simplicity usually choose autoflowers.
