Growing Guide ↓

What Are Autoflower Seeds?

Autoflowering seeds contain Cannabis ruderalis genetics that trigger flowering based on plant age rather than light cycles. This revolutionary breeding innovation means your plants will flower automatically 3-4 weeks after germination, regardless of how many hours of light they receive.

Why Canadian Growers Love Autos

  • Speed - Harvest in 8-10 weeks from seed
  • Simplicity - No light schedule management required
  • Compact Size - Perfect for small spaces and stealth grows
  • Multiple Harvests - Outdoor growers can harvest 2-3 times per summer
  • Cold Resistant - Ruderalis genetics handle Canadian climates

Best Autoflower Strains for Canada

Our fastest-finishing autos include Northern Lights Auto (ready in 8 weeks), Gorilla Glue Auto (massive yields), and Girl Scout Cookies Auto (premium quality). For outdoor Canadian grows, choose autos finishing before September frost.

Autoflower Growing Tips

Start autos in their final container—they don't like transplanting. Use light, airy soil with good drainage. Keep nutrients mild, especially in early growth. Most autos prefer 18-20 hours of light throughout their entire lifecycle for maximum yields.

Yield Expectations

Modern autoflowers yield 50-150g per plant indoors, with some XXL varieties pushing 200g+. Outdoor autos in ideal conditions can exceed 200g per plant. Multiple outdoor harvests per season can total more than a single photoperiod grow.

FAQs ↓
How long do autoflower seeds take to harvest?

Most autoflower strains are ready to harvest in 8-10 weeks from germination. Some fast varieties finish in just 7 weeks, while larger autos may take 11-12 weeks.

Can you clone autoflower plants?

Technically yes, but it's not recommended. Clones will be the same age as the mother and flower at the same time, resulting in tiny plants. Start fresh seeds for best results.

Do autoflowers need darkness?

No. Autoflowers can grow under 24-hour light. However, most growers use 18-20 hours of light to save electricity while still maximizing yields.

Are autoflower seeds feminized?

Most modern autoflower seeds are feminized (labeled "feminized autoflower" or "auto fem"). Always check the product description to confirm.

Can you grow autoflowers outdoors in Canada?

Yes! Autoflowers are ideal for Canadian outdoor growing. Plant in May-June for summer harvest, or start multiple rounds for harvests throughout the season before frost.
