Growing Conditions & Tips
- Indoor/Greenhouse: Consistent temperature and humidity support healthy growth and maximize resin production; proper airflow reduces mold risk and enhances bud development.
- Outdoor: Good mold resistance makes it adaptable to various climates, including humid or unpredictable weather.
- Extraction: High resin content and a bold terpene profile suit both flower and extraction use.
- Nutrients: A regimen tailored to growth stages, focusing on boosting terpene and resin production during flowering; monitor pH regularly.
- Training: LST maximizes light penetration and improves yield; prune lower branches and excess foliage to direct energy toward main colas.
