What it is / How it shows up:

Auto-flower is a term often seen on cannabis seed packages, gardening forums, and online store menus. It refers to cannabis strains that begin flowering automatically after a set period, typically 2-4 weeks of growth. Unlike photoperiod plants, which depend on light changes to start flowering, auto-flowers are not light-dependent. This trait comes from the Cannabis ruderalis genetics, making them ideal for those who want a quicker harvest cycle or have limited growing space. Their ability to flower under various light conditions makes them favourable for new and experienced growers.

How it’s measured or identified:

  • Growth period: Typically 8-10 weeks from seed to harvest.

  • Size: Usually smaller stature compared to photoperiod strains.

Use in context:

  • "I prefer auto-flowers for my indoor grow to save on electricity bills."

  • "Auto-flower seeds are perfect for a quick turnaround."

  • "These plants are great for beginners due to their simplicity."

Safety & compliance in Canada:

  • Growing cannabis is legal in Canada, but check provincial regulations for limits and restrictions.

  • Ensure any seeds or plants are sourced from legally approved vendors.
