About Double Mint
Double Mint is a hybrid strain that leans slightly indica and delivers pronounced minty terpenes alongside earthy and citrus notes. It performs best under controlled environments such as greenhouses or indoor rooms where humidity and airflow can be managed, making it a sensible choice for growers in temperate UK locations.
Grow Difficulty:
Growers will find Double Mint moderately challenging in damp coastal conditions due to increased mould and mildew risk. Vigilant ventilation, pruning and preventative fungicide strategies help manage those risks.
Flowering Time:
Flowering typically completes in eight to ten weeks under a stable light schedule. Some phenotypes finish toward the shorter end with good daily light intensity.
Yield:
Yields are medium-high when grown under controlled conditions and proper training. Greenhouse-grown plants can approach indoor m² figures when humidity is controlled.
Height:
Plants develop a medium to tall structure with sturdy central colas and lateral branching. Expect heights commonly between eighty and one hundred and fifty centimetres depending on training.
Environment:
In Hertfordshire Double Mint performs well under glass in a sheltered greenhouse during the growing season. It also responds positively to indoor grow rooms where humidity and airflow are tightly managed.
Climate:
In Hertfordshire the damp coastal climate increases humidity and the chance of botrytis, so careful environmental control is essential. Use dehumidifiers, raised benches and robust ventilation to counter the damp coastal climate.
