Critical Jack

Description

Critical Jack by Silent Seeds

Critical Jack by Silent Seeds is a feminized, sativa leaning photoperiod created from Jack Herer and Critical+. This places the variety between classic Haze influenced genetics and the productive, well established Critical line. Within the catalog, it stands for strong vigor, stable development, and a clearly performance oriented structure.

In cultivation, Critical Jack grows tall, vigorous, and relatively open in form. This structure supports good light penetration and airflow, which becomes especially useful as the plant expands. Outdoors, it can gain substantial height and, according to the breeder, reach up to 3 meters. It is therefore well suited to setups where sufficient space and a longer development cycle can be accommodated.

Flowering time is around 60 days. Silent Seeds lists yields of up to 625 g/m² indoors and about 1200 g per plant outdoors. THC is reported at roughly 15 to 20 percent, while the outdoor harvest window typically falls between late September and early October.

The profile also reflects both sides of the lineage. The Jack Herer background brings a more classic and refined direction, while the Critical side adds body and production strength to the overall line. Described notes include citrus, wood, incense, pine, and spice, giving the variety a broader and more distinctive aromatic profile than more narrowly fruit driven hybrids.

For growers looking for a Silent Seeds variety with Jack Herer ancestry, open plant structure, and strong production potential, Critical Jack is a clearly defined option in the range. All information is based on breeder data and reflects typical traits of the line rather than guaranteed results in every individual case.
