About Crystal Meth

Crystal Meth is a sativa-dominant hybrid prized for its energetic, euphoric effects and resinous buds. It combines a pungent citrus-diesel flavour with high THC and a low CBD balance, suiting recreational and some symptomatic uses where strong psychoactivity is wanted.

Grow Difficulty:

This cultivar is intermediate in difficulty and benefits from steady attention to humidity and airflow in a moist western coastal climate. It rewards growers who manage ventilation and feeding carefully.

Flowering Time:

Flowering generally completes in eight to ten weeks under stable conditions. Growers should watch trichome development for peak harvest timing.

Yield:

Yields are medium to high when trained and fed correctly. Indoor growers can expect roughly 400–500 g/m² under optimised conditions.

Height:

Plants tend to stretch and reach a medium to tall height, especially outdoors. Regular training helps control canopy and light penetration.

Environment:

Crystal Meth performs well in controlled indoor environments and in greenhouse setups in Essex. When grown outdoors in Essex it benefits from a sheltered spot away from prevailing moisture.

Climate:

Growing Crystal Meth in Essex requires attention to the moist western coastal climate with its higher humidity and salt air. A greenhouse or well-ventilated indoor space in Essex will help mitigate mould risk and maximise resin.
