Aim for 45 to 55 percent relative humidity during flowering and slightly higher during vegetative growth to reduce mould risk.

Water based on substrate moisture rather than a fixed schedule and let the top few centimetres dry between waterings to avoid overwatering.

Increase phosphorus and potassium while maintaining steady nitrogen early in flowering to support bud development without excessive leaf growth.

Monitor trichome colour and aim to harvest when most trichomes are cloudy with a few amber for balanced effect; in Gwynedd this often means late October.

Use dehumidifiers, boost airflow, and avoid wet foliage; removing lower leaves and spacing plants helps drying and reduces infection points.

Yes; selective defoliation and lollipopping improve light penetration and airflow which helps prevent mould in dense canopies.

Organic feeds work well but may need more frequent foliar checks for pests and slower nutrient release, so plan your feeding schedule accordingly.

Keep an eye out for spider mites, aphids and fungal gnats, and inspect plants regularly to catch infestations early.

Greenhouse cannabis cultivation offers more control over humidity, temperature and light which is especially useful in damp coastal areas like Gwynedd to manage mould and increase yields.

Many growers reduce feeds and flush lightly in the last one to two weeks to improve smoke quality, but avoid stressing plants in cool, damp weather.
