Maintain 20–26°C during lights on and slightly cooler at night. Keep humidity around 40–50% during flowering and ensure good airflow to prevent mould.

Start with a balanced NPK during vegetative growth and reduce nitrogen while increasing phosphorus and potassium during flowering. Monitor runoff EC and adjust to avoid salt buildup.

Yes, but prolonged cold can slow trichome development and stretch plants. Provide frost protection and avoid exposing buds to temperatures consistently below 10°C.

Consider a light flush one to two weeks before harvest if you use synthetic nutrients. For organic feeds a shorter flush or none at all may be preferable.

High humidity increases the risk of bud rot and mould on dense cola structures. Use dehumidifiers, improve airflow and prune lower growth to reduce moisture pockets.

Aphids, spider mites and caterpillars are common threats in the area. Regular inspections and integrated pest management reduce infestations before they spread.

Yes, low-stress training and topping suit its compact habit to expose buds to light. SCROG can maximise yields in limited vertical space.

Expect mature buds within 8 to 10 weeks of flowering under ideal conditions. Check trichomes for desired amber/clear ratios rather than relying purely on days.

Dry slowly in a dark room at 16–20°C and 50% relative humidity for 7–14 days. Cure in jars with daily burping for the first two weeks then less frequently for up to two months.

Calcium and magnesium deficiencies show under high humidity and fluctuating pH. Keep pH stable and supplement with cal-mag if symptoms appear.
