Silent Seeds Critical Jack Feminised Seeds

Critical Jack is a stable and productive 60% sativa strain. It was created by crossing Critical + with Jack Herer. Critical Jack is a resistant strain that produces very good results in various conditions and at a wide range of latitudes.

Plants can grow large having an open structure allowing good light penetration and airflow into the interior. Indoors, flowering times are around 60 days with yields expected to be in the region of 625 gr/m². Vegetative growth should be limited to 3 weeks indoors as plants stretch quite a lot once in the flowering stage. SoG and SCRoG both work well with Critical Jack, helping to control vertical growth while maximising yields.

Outdoors, these plants can grow to be 300 cm. tall producing as much as 1200 gr. or even more per plant, with harvests in northern latitudes ready anytime between late September and mid-October. Buds have a good coating of trichomes that are also appear on the tips of smaller leaves.

Critical Jack combines the Haze-derived scents and flavours of pine, incense, spice and cedar wood with the citrus character of Critical +. THC production lies between 15 - 20% with 0.01 - 0.2% CBD. The effect sees a lightly psychedelic initial phase superseded by a powerful, long-lasting surge of energy.
