CRITICAL JACK fem - Silent Seeds

Critical Jack is an extremely hardy Sativa-dominant that has been grown in locations all over the world, giving great results in a variety of climates. To speak of it is to speak of high production, genetic stability, vigor and proven quality. The Silent Seeds seed bank has used two legendary genetics for the creation of this variety: Jack Herer and Critical +.


Critical Jack plants are generally quite large, with an open structure that allows light to penetrate the entire plant and prevents the proliferation of molds or insect pests. Its leaves are quite large, with long and quite fine leaflets. In indoor crops, vegetative growth should not be prolonged for more than three weeks to avoid plants that are too tall during flowering. Its strong hybrid vigor and stability reflect the genetic line to which it belongs (Skunk #1, Northern Light and Jack Herer). The plants are very productive and offer abundant harvests of huge, compact and heavy buds. Indoors it is capable of producing up to 625 grams per square meter, and can reach 1200 grams harvested per plant outdoors. Cultivation techniques such as SCRoG or SoG will allow a considerable increase in production.


In Critical Jack, the aromatic tendencies of its two parents are subtly mixed, with a fine Haze line where notes of cedar, incense, pine and spices are combined with the citrus influence of Critical +. Jack Herer's Sativa heritage gives her an energizing, powerful and long-lasting positive effect, where her Haze lineage is marked.
