Keep relative humidity around 40-50% during flowering and lower it to the mid-40s in the final two weeks to reduce mould risk.

Use low-stress training and a light SCROG to promote even light distribution and increase bud sites without excessive vertical growth.

It can finish outdoors in good seasons, but sheltered sites and late-summer warmth are necessary to avoid rot and poor trichome development.

Switch to a bloom formulation higher in phosphorus and potassium and maintain balanced microelements to support dense bud formation.

Ensure strong circulation, remove dense inner foliage, use dehumidification, and monitor trichome and bud density to spot issues early.

Aphids and spider mites can appear in indoor rooms; use predatory mites, neem-based sprays cautiously, and keep hygiene high to prevent infestations.

Begin a gentle flush one to two weeks before harvest by reducing fertiliser salts while maintaining water and pH balance to enhance smoke smoothness.

Night temperatures slightly lower than day temperatures (about 8-10°C difference) can enhance trichome production without stressing plants too much.

For northern climate cannabis growing it is manageable for newcomers who prioritise humidity control and environmental stability, but it is not the easiest variety for a complete beginner.

Look for ambering pistils and cloudy to amber trichomes under magnification, plus a subtle slowdown in new white pistils.
