About Grimace

Grimace is tailored for growers who need a reliable, compact plant that handles cooler conditions. It combines strong terpene expression, solid yields and an approachable flowering time, with breeding aimed at producing dense, fragrant flowers suited to maritime climates.

Grow Difficulty:

Grimace suits growers with some experience and responds well to training and defence against mould. Extra care is needed during a rainy autumn harvest season to prevent bud rot and fungal issues.

Flowering Time:

Flowering completes in eight to nine weeks under ideal conditions. The variety shows consistent bud development across that period.

Yield:

Yields are moderate to high indoors and outdoors when plants are kept healthy. Proper canopy management and attention to humidity are key to reaching top yields.

Height:

Plants remain medium in height with a sturdy central cola and side branching. Expect roughly one to 1.8 metres outdoors depending on feeding and pruning.

Environment:

Grimace performs well both indoors and outdoors and is a practical choice for UK gardens in Norfolk. Outdoor plants benefit from raised beds and airflow in Norfolk to offset the damp conditions.

Climate:

Growing Grimace in Norfolk requires vigilance against wet weather and late-season rain. The plant tolerates cool maritime temperatures but needs airflow and timely protection during a rainy autumn harvest season.

Should I top Grimace?
A

Q
Do I need to feed extra during rainy periods?
A
Verified answer
Keep feed consistent but ensure plants are not overwatered; flush only if salts build up and increase potassium in late flowering to harden buds.
