London Pound Mints

Use a balanced vegetative feed for 3–4 weeks, then switch to a bloom formulation with higher phosphorus and potassium; reduce nitrogen during late flowering.

Yes; greenhouse cannabis cultivation gives protection from wind and rain while allowing humidity control, but ensure good ventilation and dehumidification to combat mould.

Harvest when most trichomes are milky with some amber for an even uplifted-relaxed effect; check multiple colas for consistent ripeness.

Topping, low-stress training and scrogging are effective to create an even canopy and increase bud sites without excessive height.

Yes; organic feeds, compost teas and microbial inoculants work well, but maintain strict hygiene to minimise fungal issues in damp climates.

Flush with plain water for 7–14 days depending on nutrient strength and media to improve smoke quality and reduce residual salts.

Under good greenhouse conditions expect roughly 400–550 g/m²; outdoor results in the UK will be lower and depend on season length and shelter.

Carbon filtration for enclosed spaces and regular airing of greenhouses will control odour; the minty scent can travel, so plan ventilation accordingly.

Aphids, spider mites and greenflies are the usual suspects; use biological control agents, insecticidal soaps and regular plant inspections.

Beginners can succeed if they pay close attention to humidity and use a protected greenhouse or controlled indoor environment; start with feminised seed and simple training.
