About Allen Wrench

Allen Wrench is an indica-dominant hybrid bred for compact growth and clear effects. You will find diesel and citrus flavours with an earthy pine finish. Plants stay short to medium and respond well to topping and low-stress training. Flowering runs about 8 to 9 weeks indoors and yields reach medium-high levels under steady feeding. Give the plants greenhouse protection in damp regions and control humidity during late flowering to reduce mould risk.

Grow Difficulty:

Growing difficulty rates as intermediate for those with some experience. You will need good humidity control in a British greenhouse to reduce mould risk.

Flowering Time:

Flowering completes in roughly 8 to 9 weeks indoors. That timing suits the UK outdoor season when you give plants greenhouse cover in late summer.

Yield:

Yields are medium to high, about 400 to 450 grams per square metre indoors with sound feeding. Many greenhouse growers across Devon and Cornwall report similar numbers under steady routines.

Height:

Plants remain short to medium, typically 60 to 120 centimetres tall. That habit suits compact grow rooms and common UK home setups.

Environment:

Allen Wrench performs well indoors and outdoors with a preference for greenhouse protection in damp regions. In places like Nottingham or Manchester you will likely prefer a greenhouse for the final weeks.

Climate:

Best climate is the UK temperate maritime pattern with mild summers and damp autumns. In the Scottish Highlands and parts of Yorkshire you will want greenhouse cover late in the season.
