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.
Big Block is an indica-dominant hybrid bred for dense, resinous buds. The strain gives a reliably heavy, calming effect when fully mature.
THC levels are moderate to high, generally sitting between 18 and 22 percent. That potency produces a clear onset followed by a deep physical relaxation.
CBD content is low, typically below one percent. This places Big Block towards recreational and symptom-targeted medicinal use rather than high-CBD therapy.
Big Block descends from Big Bud crossed with OG Kush, combining heavy yields with resinous, pungent flowers. The lineage favours compact structure and robust resin production.
These seeds are supplied as feminized to reduce the chance of male plants. Growers should still monitor for hermaphrodites when stressed by wind or light variation.
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.
Indoor flowering finishes in about eight to nine weeks under optimal conditions. Outdoors it reliably ripens before late autumn in well-sited gardens.
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.
Plants display a squat, bushy structure with strong main stems. They remain a manageable height for mixed-border plots and walled allotments.
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.
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.
The immediate effect is a mild cerebral lift that eases into full-body relaxation. At higher doses the strain can induce drowsiness and deep sleep.
The flavour profile is earthy with bright citrus peel notes on the exhale. A faint diesel background rounds out the mouthfeel.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
Plant seedlings outdoors after the last frost and when night temperatures consistently stay above 8°C, usually late May in Cornwall for a reliable finish.
Expect around 10 to 14 weeks from seed to harvest when accounting for a 2–3 week vegetative period plus an 8–9 week flowering phase.
Use windbreaks, plant near walls or hedges, and provide individual staking; consider moving pots to sheltered areas if conditions worsen.
Start with a balanced NPK feed in veg, switch to higher phosphorus and potassium during flowering, and reduce nitrogen in the final two weeks before harvest.
Yes, Big Block is bred for relatively fast flowering and can be a good option for short season outdoor cannabis growing in cooler, northerly coastal gardens.
Ensure good airflow, avoid overcrowding, remove excess fan leaves late in flowering, and harvest promptly when trichomes reach the desired ripeness.
Aphids, slugs and bud-eating caterpillars are common; monitor regularly and use organic controls like neem oil and hand removal where appropriate.
Yes, low-stress training and topping can open up the canopy and improve light penetration, increasing yields while keeping height manageable.
Many growers reduce or stop feeding in the final two weeks to improve flavour and burn quality, but follow your nutrient manufacturer's guidance.
Cannabis cultivation remains illegal in the UK for recreational use; check current laws and licences before growing for medical or research purposes.
