Sour Kush

Use 12 hours light and 12 hours dark to trigger and maintain flowering; ensure the dark period is uninterrupted for consistent bud development.

Maintain good airflow, control humidity especially during late flowering, and prune lower growth to improve circulation around bud sites.

Start bloom nutrients at the switch to 12/12 and follow a conservative schedule, watching runoff EC to avoid nutrient lockout.

Yes, in southern sites with good shelter and sun it performs well, but monitor for heavy rain and provide protection if autumn weather arrives early.

CO2 can boost yield if you have strong lighting and sealed conditions, but it increases complexity and is not essential for moderate grows.

Many growers flush with plain water for the final 7-10 days to clear excess nutrients, adjusting the duration based on plant condition.

Keep an eye out for aphids, spider mites and thrips, especially during warm spells and when plants are stressed.

Yes, low-stress and high-stress training both work well to open the canopy and maximise light penetration to dense buds.

Scale nutrient doses to pot size and plant load, and monitor runoff EC rather than following bottle feeds rigidly to avoid overfeeding.

Absolutely; Sour Kush benefits from controlled climate cannabis growing methods such as precise humidity control, temperature cycling and staged ventilation to manage resin production and minimise mould risk.
