What Are Autoflowering Seeds?
Autoflowering seeds contain Ruderalis genetics that trigger flowering based on plant age, not light cycles. This means they flower automatically without switching to a 12/12 light schedule.
Most autoflowers complete their entire lifecycle in 8-12 weeks from germination. This speed makes them ideal for multiple harvests per season.
Why Autoflowers Are Perfect for Canada
Canada's shorter outdoor growing season makes autoflowers especially valuable:
- •Fast finish: Harvest before fall frost arrives, even in northern provinces.
- •Multiple harvests: Plant in May, harvest in July, plant again for a second harvest in September.
- •No light schedule: Indoor growers can keep lights on 18-20 hours throughout the entire grow.
- •Compact size: Most autoflowers stay under 120cm, fitting easily in small tents or balconies.
Autoflowers are the fastest path from seed to harvest for Canadian growers.
Autoflower vs Feminized Seeds
The main difference is flowering trigger. Photoperiod feminized seeds need a 12/12 light cycle to flower. Autoflowers flower on their own timeline.
Autoflowers are easier to grow but typically produce smaller yields per plant. Photoperiod strains offer more control and larger harvests but require more experience. Many growers start with autoflowers and graduate to photoperiod strains as they gain confidence.
Frequently Asked Questions
How long do autoflowers take from seed to harvest?+
Most autoflowers complete their lifecycle in 8-12 weeks from germination. Some fast varieties can finish in as little as 7 weeks.
Do autoflowers yield as much as photoperiod strains?+
Individual autoflower plants typically yield less than photoperiod plants. However, their fast cycle allows multiple harvests per season, which can equal or exceed total annual yield.
Can I grow autoflowers outdoors in Canada?+
Yes. Autoflowers are ideal for Canadian outdoor growing. They finish quickly enough to harvest before fall frost in virtually every province.
Do autoflowers need special nutrients?+
Autoflowers use the same nutrients as photoperiod plants but in lower concentrations. Start at 1/4 to 1/2 strength and increase gradually. Overfeeding is the most common autoflower mistake.
Can I top or train autoflower plants?+
Light LST (low-stress training) works well. Topping is debated — some growers top autoflowers successfully, but the limited veg time means recovery is tighter. For beginners, stick with LST only.
