Autoflower vs. photoperiodic: the complete comparison

The choice between autoflower and photoperiod cannabis strains determines the entire cultivation process:

**Autoflower cannabis**

Flower automatically after 2-4 weeks, regardless of the light cycle.

*Advantages:*

- Fast harvest (8-12 weeks total)

- Easy cultivation for beginners

- No light cycle change necessary

- Compact size, discreet

- Multiple harvests per year possible

- More resistant to light interruptions

*Disadvantages:*

- Lower yields per plant

- No cloning possible

- Less control over size

- Usually lower THC content

- More expensive (new seeds with each grow)

*Recommended autoflower strains:*

- Northern Lights Auto

- Blue Dream Auto

- Amnesia Haze Auto

- White Widow Auto

**Photoperiod cannabis**

Flowering only with 12/12 hours light/dark cycle.

*Advantages:*

- Higher yields possible

- Complete control over growth

- Cloning for genetic consistency

- Higher THC potentials

- Cost effective (mother plants)

- Longer vegetation phase = larger plants

*Disadvantages:*

- Longer cultivation time (4-6 months)

- More complex light control required

- More susceptible to light interruptions

- Requires more experience

**Growing differences:**

*Autoflower cultivation:*

- Light cycle: 18/6 or 20/4 continuous

- Smaller pots (11-19 litres)

- Less training (gentle LST only)

- Shorter nutrient programmes

*Photoperiodic cultivation:*

- Vegetative: 18/6, flowering: 12/12

- Larger pots (19-40+ litres)

- All training techniques possible

- Longer, intensive fertilisation

**Decision support:**

- Beginners → Autoflower

- Experienced growers → Photoperiodic

- Fast harvest → Autoflower

- Maximum yields → Photoperiodic

- Small space → Autoflower

- Preserve genetics → Photoperiodic
