Fatty Arbuckle

Use 18/6 during vegetative growth and switch to 12/12 for flowering; maintain consistent dark periods to avoid stress.

Prioritise airflow, prune lower growth, and use dehumidifiers or ventilation; timely harvest and location choice reduce rot risk.

Begin bloom-specific nutrients at the switch to 12/12 and reduce nitrogen while increasing phosphorus and potassium during weeks 3–6 of flowering.

Aphids, spider mites and thrips can appear; regular inspections, sticky traps and biological controls work well in small grows.

Yes, it tolerates moderate night-time drops but avoid prolonged temperatures below 12°C to prevent slowed metabolism and bud set issues.

Both topping and SCROG are effective to increase yields and even canopy; choose based on your space and training experience.

You should see initial bud set within 2–3 weeks, with significant fattening from week 4 onwards until harvest.

Dry slowly at 18–21°C with 50–60% RH to preserve terpenes and avoid harsh smoke.

Controlled climate cannabis growing is highly recommended for Fatty Arbuckle in the UK to manage humidity and temperature and reduce disease risk.

Check trichomes under magnification for cloudy to amber heads and inspect pistils for around 70–90% darkening depending on desired effect.
