Dirty Dozen

Yes, Dirty Dozen adapts well to northern climate cannabis growing when cultivated indoors with strict humidity control and consistent temperatures.

Use extraction fans, dehumidifiers and oscillating fans to keep air moving; lower relative humidity in flowering and remove dense fan leaves to improve airflow.

Switch to 12/12 for flowering and maintain even, high-intensity light; ensure dark periods are uninterrupted to avoid stress and hermaphroditism.

Harvest when most trichomes turn milky with some amber for a balanced effect; check multiple sites across the canopy in the final week.

Feed a balanced NPK during vegetative growth then reduce nitrogen and increase phosphorus and potassium in flowering to support bud development.

Spider mites and thrips can be problems in indoor grows; use regular inspections, sticky traps and biological controls where possible.

Dry slowly in a dark, cool room until stems snap, then cure in airtight jars with daily burping for the first two weeks to stabilise flavour and potency.

Yes, organic soils and slow-release amendments work well, but keep an eye on humidity since organic media can retain moisture and raise mould risk.

Topping and low-stress training help flatten the canopy and improve light penetration for larger yields, especially in indoor setups.

Keep daytime temperatures around 20–26°C and allow a 3–5°C drop at night; avoid prolonged heat spikes that stress plants and reduce terpene retention.
