About Critical Purple

Critical Purple is an indica-dominant strain combining heavy yields and purple colouration with a relaxed, sedative profile. It thrives under careful management in temperate, maritime regions and rewards growers who control humidity during a rainy autumn harvest season.

Grow Difficulty:

Growing Critical Purple is moderately challenging and benefits from steady attention during flowering. Watch for mould risk during the rainy autumn harvest season and provide airflow and selective pruning.

Flowering Time:

Flowering generally finishes in 7 to 9 weeks under good conditions. Outdoor plants in the UK often ripen by mid to late autumn with careful timing.

Yield:

Yields can be generous when plants receive ample light and nutrients. Outdoor crops in a sheltered spot frequently reach 400–600 grams per plant in favourable seasons.

Height:

Plants stay compact with a sturdy, bushy structure ideal for sea of green and scrog methods. Branching is predictable and supports heavy, resinous colas.

Environment:

Indoors this strain performs well in controlled tents with dehumidification and good circulation in Leeds. Outdoors in Leeds it benefits from a sunny, sheltered aspect to avoid wind and excess rain.

Climate:

Growing Critical Purple in Leeds requires planning for damp, cool conditions and the potential for late-season rain. In Leeds it is best placed where airflow and shelter reduce mould risk during a rainy autumn harvest season.
