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.

Grow Difficulty:

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 Time:

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.

Yield:

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.

Height:

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.

Environment:

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.

Climate:

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.
