Sour Chem

Sour Chem is best for growers with some experience because it needs vigilant humidity and mould control. Beginners can succeed with guidance and careful environmental management.

Maintain steady airflow, use fans and vents, and keep relative humidity below 55% during flowering. Remove dead plant material and monitor daily for early signs of bud rot.

Harvest when trichomes show a mix of cloudy and a few amber heads for a balanced high. Check buds frequently in the final week since humid conditions can accelerate rot risk.

Provide a balanced NPK feed during vegetative growth and shift to higher phosphorus and potassium during flowering. Avoid overfeeding and flush lightly if nutrient burn appears.

Yes, but choose a sheltered, well-ventilated site and consider a greenhouse or cloche to reduce moisture exposure. Regular inspection and early disease management are essential.

Selective pruning and topping encourage lateral growth and can increase overall yield by creating multiple bud sites. Avoid heavy pruning late in flowering as it can delay ripening.

Aphids, spider mites and whiteflies are common, especially in humid setups. Introduce beneficial insects and use targeted organic controls to keep infestations low.

Sour Chem can work outdoors in cooler summers if planted early and given a sunny, sheltered microclimate. In wetter years, a greenhouse or rain protection is strongly recommended to prevent mould.

Curing for two to four weeks in a cool, dark place improves flavour, with some growers seeing further improvements at six to eight weeks. Keep jars burped initially to avoid excess moisture and mould.

Low-stress training and topping work well to manage stretch and promote canopy evenness. Combine training with timely defoliation to improve airflow around bud sites.
