Critical Jack

Critical Jack by GB Seeds

Critical Jack is a sativa-dominant (70%) poly-hybrid obtained from the cross of a Jack Herer and a Critical Mass, resulting in a plant of great vigor and premium quality production, both outdoors and indoors under artificial light.

This strain features:

• Great genetic stability
• Protection against pests and mold.
• Its buds are large, compact, elongated, and rock-hard, possessing a rich layer of trichomes.

Without a doubt, it is an ideal strain for those interested in massive crops.

Taste and aroma of feminized Critical Jack

This feminized seed stands out for an explosion of intense and perfectly balanced flavors. At first hit, a very characteristic sweet and fruity base of Critical+ is perceived, with its fresh citrus touch reminiscent of freshly grated lemon. But soon the elegant and penetrating imprint of the Haze lineage appears, with deep notes of incense, cedarwood, warm spices, and a slight hint of pine.

Effects of Critical Jack

Critical Jack is a strain with clear sativa dominance, so it's noticeable from the first puff. Its effect is powerful, stimulating, and prolonged, perfect for those seeking more mental than physical sensations. You'll notice your mind activating almost instantly: a wave of positive energy, mental clarity, and motivation emerges, accompanied by an inevitable smile that marks the beginning of the high.

Its duration is also a strong point: the effect is maintained for hours without losing intensity, making it a perfect ally for lovers of potent sativas.

How to grow Critical Jack indoors: tips and production

It is an ideal variety for SOG cultivation indoors, producing large central buds in a fairly short time. We recommend up to 16 plants in square pots of all sizes of 7 liters to achieve optimal results. We will have it ready in 9 to 10 weeks of flowering from when it shows its sex after the photoperiod change. Production is also among the highest, up to 600g/m2 dry.

How to grow Critical Jack outdoors: pruning, production, and harvest

Outdoors, it is a large plant that tolerates all types of pruning and bending. This way we can increase production and standardize the size of the buds. It will be ready for harvest around mid-October, a little later than its sister Critical+ but reaching a much higher production, up to 1kg dry and plants up to 3 meters tall if we plant it early in spring as soon as the season begins. If we do not want enormous plants, we recommend waiting until mid-June and we will obtain smaller sized plants.
