Start seeds indoors in late March to early April to give plants a strong root base before moving out after the last frost.

Increase airflow around the canopy, remove lower foliage to improve ventilation, and consider a dehumidified polytunnel if the season turns consistently wet.

Use a balanced nutrient schedule with slightly higher phosphorus and potassium during flowering and reduce nitrogen in the final weeks.

Light defoliation can help airflow and light penetration, but avoid heavy leaf removal during wet spells when plants need foliage to cope with stress.

Inspect plants weekly, encourage predators, use neem or biological controls as needed, and isolate any infected plants promptly.

Look for ambering pistils and a mix of clear and cloudy trichomes; harvest timing depends on desired effect, with slightly cloudier trichomes giving a stronger high.

Dry slowly in a cool, dark place with 45–55% relative humidity, then cure in jars, burping daily for the first two weeks to stabilise flavour and potency.

Yes, a ventilated greenhouse extends the effective season and reduces the risk of late-season weather damage while allowing better humidity control.

Sudden yellowing, leaf burn and stunted growth can indicate lockout; flush with pH-balanced water and reassess feeding strength and substrate pH.

In high humidity cannabis cultivation, focus on strong horizontal and vertical airflow, reduce canopy density, use fans and dehumidifiers where possible, and monitor leaf wetness to avoid mould.
