Choosing What Fits Your Grow Room

When choosing cannabis seeds, one of the most important decisions you’ll face is whether to go for autoflower or feminized seeds. Both types have unique advantages depending on your space, time, and experience level. In this guide, we’ll compare the two and help you decide what fits your grow goals best.

What Are Autoflower Cannabis Seeds?

Autoflower seeds grow into plants that begin flowering automatically after a few weeks of vegetative growth—usually around 3 to 4 weeks—regardless of the light schedule. They are ideal for beginners and growers who want fast results.

Autoflower cannabis plant

  • Fast harvest: ~8–10 weeks from seed to bud
  • Small and discreet plants
  • Great for indoor, balconies, or stealth grows
  • Less maintenance (no need to change light cycles)

Popular Example: Amnesia Lemon Autoflower – 21% THC, 500g/m² yield

Feminized seeds are bred to produce only female plants—those that yield buds. They require a shift in light cycle (typically 12/12 light/dark) to start flowering, but they reward you with larger plants and higher yields.

Feminized cannabis plant

  • Bigger yields and stronger genetics
  • Perfect for advanced growers
  • Flowering triggered by light schedule
  • Longer grow time: ~12–16 weeks total

Popular Example: Blueberry Feminized – 15% THC, 500g/m² yield

Which Should You Choose?

If you’re new to growing or have limited space and want fast, reliable harvests, autoflower seeds are your best bet. But if you’re aiming for maximum yields and want full control over the grow cycle, go with feminized seeds.
