About Heat Wave
Heat Wave is a sativa-dominant hybrid developed to perform in cooler maritime climates while preserving an energetic, uplifted effect. It produces citrus and pine-forward flavours with resinous buds that respond well to training and careful feeding, and the genetics were selected for stability and cold tolerance.
Grow Difficulty:
Grow difficulty is intermediate; plants tolerate cool weather but demand active mould prevention. Extra vigilance is required during the rainy autumn harvest season to avoid bud rot and nutrient leaching.
Flowering Time:
Flowering generally completes in 8 to 10 weeks under optimal light. Outdoors in the UK it commonly finishes in late autumn if planted early enough.
Yield:
Yield is medium to high when grown with proper feeding and training. Indoor growers can expect around 450–500 g/m² while outdoor yields depend on season length and care.
Height:
Plants reach a medium height of about 1 to 2 metres with a bushy, upright habit. They produce long colas and benefit from pruning and low-stress training to control stretch.
Environment:
Indoor grows allow tight climate control and steady resin production, but outdoor trials in York have still produced good results. Outdoor in York the strain shows vigour but needs shelter and airflow as many growers in York harvest into wet weather.
Climate:
Growing Heat Wave in York requires close attention to humidity because the rainy autumn harvest season can promote bud rot. Shelters, good airflow and timely harvest are essential in York to protect yields during the rainy autumn harvest season.
