Fast Growing Cannabis Seeds

What makes cannabis seeds “fast growing”?

Fast growing cannabis seeds produce plants with:

• Shorter flowering periods
• Faster transition from vegetative growth to flowering
• Predictable finishing times

In practical terms, this means strains that can be ready to harvest in 6–8 weeks of flowering, or 8–10 weeks from seed to harvest in the case of autoflowers.

Genetics play the biggest role here. Indica-dominant strains and autoflowering varieties are naturally quicker to finish than most sativa-dominant photoperiod plants.

Autoflowers vs fast-flowering photoperiod strains

Two types of cannabis seeds are typically considered “fast growing”:

Autoflower seeds

Autoflowers are the fastest option overall. These plants flower automatically based on age rather than light cycles and often complete their entire life cycle in 8–10 weeks.

They are popular with growers who:

• Want the quickest possible harvest
• Have limited space or time
• Prefer a simpler grow without light cycle changes

Fast-flowering photoperiod seeds

Some indica-dominant photoperiod strains have been bred to flower exceptionally quickly, often finishing in 6–8 weeks of flowering once switched to a 12/12 light cycle.

These are a good option for growers who:

• Want more control over plant size
• Prefer traditional photoperiod growing
• Are aiming for slightly larger plants while still keeping grow time short

Who should choose fast growing cannabis seeds?

Fast growing seeds are well suited to:

• Indoor growers working with limited time
• Outdoor growers in regions with short summers
• Beginners looking for a quicker, more forgiving grow
• Growers planning multiple harvests per year

Shorter grow cycles also reduce exposure to common issues such as pests, mold, and environmental stress, making fast-finishing strains a practical choice for many setups.

Typical grow timelines

While exact timing depends on strain and conditions, most fast growing cannabis seeds fall into these ranges:

• Autoflowers: 8–10 weeks from seed to harvest
• Fast indica photoperiods: 6–8 weeks of flowering after veg
• Total indoor time: Often 9–12 weeks depending on veg length

Choosing stable genetics and maintaining consistent conditions will always have more impact than trying to rush growth through intensive methods.
