Editorial profile
Jack Plant in detail
Origin & classification
With Jack Plant, the practical breeding goal takes precedence over a completely documented pedigree: Advanced Seeds describes a productive, sativa-dominant Jack Herer cross with strong growth and large flowers. The structured fields name Jack Herer and Haze, while the raw data additionally lists Jack Herer and Northern Lights #5 as well as Haze. As these variants do not fit together consistently, the exact parent combination cannot be determined reliably. The only certainty is the explicitly stated connection to Jack Herer.
Aroma & flavour
The continuous description provides a fairly specific cultivation profile. Indoor plants are said to reach heights of approximately 75 to 150 centimetres and have a flowering time of 60 to 70 days. Outdoors, Jack Plant can become considerably larger; the source describes three to five metres and a harvest around mid-October. These measurements are not fixed results, but breeder-related guidelines that depend on climate, pot volume, vegetative period and care. Resistance to powdery mildew is highlighted as another characteristic.
Terpene profile
The yield data also characterises Jack Plant as a performance-oriented strain. For indoor cultivation, the source states 400 to 500 grams per square metre and generally describes the plants as very productive. Large buds are also mentioned, without providing further details about their shape, density or resin coverage. The reliable picture therefore remains focused on a few but useful characteristics: substantial vertical growth, large flower clusters, a medium-length flowering period and potentially high yield. By contrast, the data set contains no reliable information on aroma and flavour.
Effect tendency
The source describes the effect only in general terms as typical of a sativa. Specific descriptions such as euphoric, focused or relaxing are absent, so a more precise statement would be speculative. Although a THC value of 20 percent is given, it should be understood as a source value dependent on batch and phenotype. Editorially, Jack Plant is therefore particularly suited to comparison based on growth and cultivation rather than on a supposedly precise effect or aroma profile. Its recognisable character lies in the combination of its connection to Jack Herer, pronounced outdoor size, large flowers and the robustness described by Advanced Seeds.
