Sour Runtz

Maintain daytime temperatures of 20–26°C and slightly cooler nights; avoid prolonged heat spikes to reduce stress.

Use good ventilation, extract fans and dehumidifiers to keep humidity below 50% in flowering; prune lower growth to improve airflow and reduce mould risk.

Yes. Low-stress training and a light SCROG will expose more bud sites to light and increase overall yield without excessive height.

Check trichomes: harvest when most are cloudy with some ambers for balanced effects; harvest earlier for more cerebral highs and later for sedative effects.

Yes, in sheltered, sunny spots with good drainage; protect plants from persistent rain and ensure adequate airflow to minimise mould.

Reduce nitrogen and increase phosphorus and potassium in mid to late flowering to support bud development and resin production.

A short flush of 7–10 days with plain water can improve taste, but monitor plant health and potency rather than following a rigid rule.

Spider mites and thrips can be an issue; use regular leaf inspections, beneficial insects and neem or soap sprays as preventative measures.

Yes, with training and regular pruning it fits smaller plots or large pots and can remain compact while producing quality yields.

Because of its sensitivity to humidity and tendency to form dense buds, choose well-ventilated sites and consider greenhouse ventilation and late-season protection when planning outdoor cannabis cultivation.
