About Gas Runtz

Gas Runtz performs strongly in controlled environments and responds well to greenhouse cultivation in Gwynedd. It combines heavy resin production with a complex aroma of diesel, sweet candy and citrus, and requires attentive humidity control in a damp coastal climate to reach full potential.

Grow Difficulty:

Growing Gas Runtz in a damp coastal climate presents some challenges. It requires keen hygiene and airflow to prevent mould and bud rot in humid coastal conditions.

Flowering Time:

Flowering usually completes in eight to ten weeks under optimal conditions. Outdoor harvests in the northern UK typically finish in late September to October.

Yield:

Yields are medium to high with proper care and feeding. Greenhouse crops in sheltered sites can match indoor numbers.

Height:

Plants develop a compact yet bushy structure with several robust colas. Expect heights from approximately 0.8 to 1.8 metres depending on training.

Environment:

Gas Runtz performs well under glass and in guarded outdoor spaces in Gwynedd. In Gwynedd a greenhouse will protect buds from coastal damp and wind while allowing full development.

Climate:

In Gwynedd this strain benefits from a protected environment due to the damp coastal climate. Provide good ventilation, dehumidification and timed heat to prevent mildew and rot.
