Berry

Maintain relative humidity around 50–70% in veg to support healthy transpiration and leaf growth without encouraging mould.

Reduce humidity to about 40–50% during flowering to lower the risk of bud rot and fungal infection as flowers bulk up.

For high humidity cannabis cultivation, increase ventilation, use dehumidifiers where possible, keep good air circulation between branches and avoid late-season watering that wets the canopy.

Switch to 12/12 light once plants have reached desired size; this allows control over final height and helps ensure flowering completes within eight to nine weeks.

Berry tolerates mild cool nights but is sensitive to prolonged cold and damp; avoid exposing plants to sustained low temperatures late in the season.

Watch for spider mites, aphids and powdery mildew, especially where humidity and air movement are suboptimal.

Berry responds well to moderate feeding; heavy nutrients can burn smaller plants, so prefer steady, balanced feeds and monitor leaf response.

Most phenotypes finish around eight to nine weeks, though slight variations occur; select phenos early if you need faster finishing outdoors.

Light, targeted defoliation can improve airflow and light penetration, but avoid over-pruning which stresses plants and can slow bud development.

Dry in a cool, dark room with 45–55% relative humidity and gentle airflow to preserve terpene aroma and reduce mould risk during cure.
