Use a rich, loamy soil with good drainage and a lively soil biology; avoid waterlogged mixes and amend with compost and perlite.

Keep relative humidity lower during flowering with dehumidifiers or increased airflow and remove dense lower growth to reduce mould risk.

Monitor trichomes and aim to harvest when most are cloudy with some amber, usually early October in mild coastal regions.

Yes, it responds well to organic feeding schedules using compost teas, worm castings and kelp; focus on building soil life rather than synthetic nutrients.

Shift to lower nitrogen and increased phosphorus and potassium as flowering progresses, using organic sources like bone meal and kelp.

It shows moderate resistance but in damp conditions it still needs proactive canopy management and airflow to prevent issues.

Topping and low-stress training work well to control height and improve light penetration, especially in tall outdoor growth.

Coastal influence can moderate temperatures but also raise humidity; plan shelter and drainage accordingly.

Start with a well-composted base, supplement with worm castings and fish or seaweed teas during veg, and add phosphorus-rich amendments at flowering.

Begin by building a living soil using high-quality compost, aeration (perlite or grit), worm castings and diverse organic amendments, then nurture microbial life with regular compost teas and mulch.
