Specifications of the Critical Jack cannabis seed

Structural development

Critical Jack is a cannabis variety that produces plants with the following characteristics:

  • large size;
  • an open structure;
  • allows light to enter well;
  • allows good aeration during flowering.

Its leaves are quite large, with long and thin leaflets. Like its parents, its strong vigor and stability reflect the noble genetic lineage to which it belongs (Skunk#1, Northern Lights and haze). By cultivating Critical Jack collection cannabis seeds, you have the possibility to obtain very productive plants, capable of offering you a generous harvest whose "premium" quality level is far above many current varieties. Critical Jack is a cannabis plant that will remain a true "cannabis reference" of the feminized dynamic of this last decade.

Yield

Critical Jack is a cannabis hybrid that guarantees, both for the passionate grower and the legal producer, to obtain very abundant harvests. It is characterized by large compact and heavy flowers, whose homogeneity and qualitative aspect will certainly surprise the most demanding among you! Critical Jack is a cannabis variety whose resin production is not left behind, as we can see a thick layer of trichomes even on the tips of the small leaves. Indoors, a crop grown using the Critical Jack collection cannabis seed will offer you a yield of up to 625 g/m2 and at least 1200 g/plant outdoors. Reliability and quality are our priority...

Odors and flavors

Critical Jack is a cannabis cultivar that subtly blends the contrasting and complementary aromatic trends of Jack Herer and C+. This is why we find in it the fine and subtle complexity of the haze lineage, with notes of cedar, incense, pine and spices, which delicately combine with the intense and fresh citrusy influence brought by Critical +. An explosive fusion of flavors with a long finish.

Effects

The Critical Jack collection cannabis seeds will offer you pleasant moments and fill you with emotions. The Sativa influence of Jack Herer brings a powerful long-lasting energizing effect. You will certainly feel a slightly psychedelic impulse, specific to the Haze lineage. Critical Jack is a collection cannabis seed that produces more mental than physical sensations (60% Sativa). It's an ideal cannabis cultivar for enjoying pleasant moments according to your desires.

    Merchant response

    Hello Martin, I hope you're well, and I can fully understand your disappointment if the facts are true, but perhaps it would be more effective for a rapid resolution of the problem encountered, to contact us quickly and directly by e-mail at [email protected], in order to explain in detail what happened, but also and above all to send us at least one photo or a supporting video, so that we can visually observe the facts and quickly offer you a generous compensatory solution to the problem encountered. In my opinion, this approach is far more resolute and in your best interests. It seems perfectly logical and legitimate for us to demand at least one piece of evidence before agreeing to replace the defective products. Thank you for your understanding of the Martin situation. We look forward to receiving your message and the information you have requested, so that we can help you as quickly as possible. Good day to you and best regards. Damien, SILENT SEEDS TEAM
