Expect around 20–24% THC in well-grown phenotypes, though lab results vary by phenotype and grow conditions.

Flowering commonly completes in eight to nine weeks under stable lighting and nutrient regimes.

It is best described as intermediate; novices can succeed with close attention to humidity, nutrients and basic training.

Use open airflow, lower humidity during late flowering, remove dense inner foliage and employ a dehumidifier or heater in the greenhouse to reduce condensation.

Yes; in Hertfordshire a greenhouse offers shelter and extended season, but you must maintain ventilation, shading and winter heating to avoid humidity-related issues.

Provide a balanced vegetative feed with higher nitrogen, then switch to lower nitrogen and higher phosphorus and potassium in flower; follow manufacturer EC/ppm recommendations and flush mildly before harvest.

Feminised seeds are recommended for controlled canopy management and higher predictable yields; autoflowers suit very short-season growers but yield less.

Ensure rapid air exchange, install adjustable vents, use shade cloth on hot days, monitor humidity closely and consider heat and dehumidification for late summer in coastal zones.

Spider mites, thrips and powdery mildew are common; botrytis can attack dense buds in high humidity, so inspect regularly and act at first sign of infestation.

Aim for late September to early October in a greenhouse, checking trichomes for a mix of cloudy and amber depending on your desired effect.
