About 9Lb Hammer

9Lb Hammer is an indica-dominant variety bred for big buds and resin. The plant stays compact indoors and responds well to topping and LST. You should manage humidity and airflow to protect dense flowers from mould in damp spells. Yields are high with proper feeding and a solid bloom programme. Expect earthy and diesel flavours with a sweet finish that appeal to growers who like thick, aromatic flowers. Growers from Bristol to Edinburgh use greenhouses to extend the season and protect the final weeks.

Grow Difficulty:

Growing 9Lb Hammer rates as moderate difficulty for most growers. You will need to manage humidity in UK summers and use a greenhouse to protect buds during autumn.

Flowering Time:

Indoor flowering takes about seven to nine weeks. Outdoors it usually finishes before the heavy autumn rains in most of England and Wales.

Yield:

Yields are high when you use good feeding and training methods. Greenhouse growers from Cornwall to Nottingham report solid harvests late September.

Height:

Plants stay short to medium indoors, which suits height-limited grow rooms and tents. Outdoors in a sheltered garden they may reach up to two metres.

Environment:

9Lb Hammer suits both indoor setups and greenhouse grows. In open gardens place it in a sheltered spot to reduce damp and wind exposure.

Climate:

Best climate is mild maritime with warm spells and good sun plus shelter from constant rain. In Cornwall and Devon a greenhouse works well, while growers in Scotland should add extra protection from wind and rain.

Which bloom nutrients work best for big buds?
