About Jacks Cleaner
Jacks Cleaner is a sativa-dominant hybrid bred for clarity and resin production, offering bright citrus and pine notes alongside an energetic cerebral effect. It suits intermediate growers who can manage canopy and moisture, and it performs well outdoors in sheltered coastal sites such as those found in Somerset.
Jacks Cleaner is a sativa-dominant hybrid bred for clarity and steady energy. It leans on sativa traits while keeping a manageable structure.
THC levels typically range from 18% to 23% in well-cultivated plants. Expect pronounced psychoactive effects at the upper end of that range.
CBD remains low, generally under 1% in most phenotypes. This strain is not chosen for CBD-led therapeutic use.
Jacks Cleaner traces to Jack Herer x Cleaner in its breeding history. The cross aims to combine clear-headed sativa traits with resin-rich structure.
Seeds are commonly offered as feminised to ensure a high proportion of flowering females. Photoperiod feminised seeds allow growers control over vegetative duration.
Growing Jacks Cleaner under a cool Scottish outdoor climate demands attentive feeding and careful site selection. It suits growers with intermediate skills who can mitigate wind and damp.
Flowering typically completes in 8 to 10 weeks under 12/12 conditions. Outdoor plants in Somerset often finish by late September to mid October in a cool year.
Yields are medium to high when plants get adequate sun and air, typically 400–600 g per plant outdoors. Coastal sites in Somerset can push yields upward if mould pressure is low.
Plants grow medium to tall with a strong central cola and airy side branches. Outdoor specimens can reach 1.5 to 2.2 metres in sheltered spots.
Jacks Cleaner thrives outdoors in Somerset when given a sheltered, sunny position near the coast. Indoors it performs well in a sea of green or SCROG setup with a stretch during early flower.
In Somerset, Jacks Cleaner can be productive despite a cool Scottish outdoor climate, provided plants are placed where they catch maximum sun and avoid prevailing winds. Regular canopy maintenance and prompt mould checks are essential to succeed in that environment.
The high-THC profile delivers an uplifting, focused head high that stays functional. Later effects bring gentle physical relaxation without heavy sedation.
Flavours are bright citrus and pine with an earthy undertone. Smoke or vapour carries a clean, sharp finish.
Frequently Asked Questions
Common questions about this strain, covering growth, effects, and suitability for UK conditions.
Use a balanced NPK feed in vegetative growth and reduce nitrogen slightly once flowering begins; follow a moderate EC and avoid overfeeding to reduce stretch-related issues.
Keep the canopy open by selective pruning, maintain good airflow, site plants on a slope or raised bed if possible, and harvest promptly if autumn rains arrive.
Harvest when trichomes are mostly cloudy with some ambers for a balanced effect and monitor pistils for around 70–90% darkening; in cool years aim for the earlier end of the harvest window.
It tolerates coastal exposure better than many strains but benefits from a windbreak or hedging to limit direct salt spray and mechanical damage.
For coastal climate cannabis cultivation choose sheltered, sun-facing spots, prioritise airflow and quick-drying canopy structures to manage moisture and salt-laden winds.
Feminised seeds are practical for growers seeking to maximise flowering females without sexing, while regulars are useful for breeding and selecting robust males.
Watch for aphids, slugs and spider mites; use integrated pest management with manual removal, predatory insects and limited organic treatments as a first line of defence.
Dry slowly at 18–22°C with 50–60% humidity until stems snap, then cure in jars with daily burps for the first fortnight to develop flavour and reduce harshness.
Yes, it roots reliably from healthy, vegetative cuttings; keep clones warm and humid with a stable light cycle until established.
Cultivating cannabis is illegal in the UK without a licence, so check current laws and consider legal risks before undertaking any growing activity.
