About Big Block

Big Block is bred for growers who need a robust, relatively quick-finishing plant that still produces bulked, resinous colas. The variety combines reliable flowering, a compact stature and a flavour profile leaning towards earth and citrus, making it suitable for coastal gardeners in Cornwall and for indoor setups where tight control is possible.

Grow Difficulty:

Growing difficulty is intermediate and requires attention to training and nutrient balance. Plants need staking and wind protection in windy coastal growing areas to avoid branch damage.

Flowering Time:

Indoor flowering finishes in about eight to nine weeks under optimal conditions. Outdoors it reliably ripens before late autumn in well-sited gardens.

Yield:

Yield is generous for a short-season variety when trained and fed correctly. Outdoor plants can produce substantial central cola yields in sheltered Cornwall gardens.

Height:

Plants display a squat, bushy structure with strong main stems. They remain a manageable height for mixed-border plots and walled allotments.

Environment:

Big Block does well indoors where humidity and light cycles are controlled. Outdoors it performs best in Cornwall when planted in a sheltered, sun-facing spot.

Climate:

Growing Big Block in Cornwall means planning for salt-laden air and frequent gusts, so place plants behind windbreaks and inside microclimates where possible. Windy coastal growing areas demand regular checks on staking and soil moisture to avoid plant stress.

Q
Any tips for feeding in coastal soil?
A
Verified answer
Coastal soils can be sandy and low in organic matter, so add compost and slow-release fertiliser to improve water retention and nutrient availability.

Q
I get a lot of wind on my headland plot; what shelter works best?
A
Verified answer
Use a combination of temporary windbreaks, chestnut stakes and neighbour-friendly hedging to reduce gusts without blocking sunlight.

Q
When should I start checking trichomes for harvest?

Q
Does Big Block respond well to LST?
A
Verified answer
