Critical Jack is a cannabis hybrid of the highest quality. It is easy to grow, quite fast-flowering for a strain of this quality and can grow quite large outdoors. It is a prodigious producer that outstrips even Critical + for yields. Indoors a SCROG system is perfect as long as the veg. period is kept quite short otherwise its propensity to stretch could cause some issues. Here it can provide the grower with harvests of 625 gr/m 2 in 60 days of flowering. Outdoors, where it can reach 3 meters tall, it needs plenty of sunshine and warmth otherwise a greenhouse environment is recommended to fulfil its potential which amounts to up to 1200 gr/plant with harvest being late September / mid-October in the northern hemisphere. The overall appearance of Critical Jack can look a bit shabby as the light green leaves hang rather limply but this is nothing to worry about as you will see as soon as the explosion of flowers will show.

Critical Jack is a 60% sativa cannabis strain that was bred by crossing Critical + with Jack Herer. It is a highly productive strain with high levels of THC.

In terms of aroma and flavour you will find citrus fruit, incense, exotic wood and spices with some phenos emphasising the lemon/woody character. THC production is very high at 21% giving a very long-lasting, cerebral high.

Critical Jack has won several awards including: 1st prize in the “Outdoor Sativa” category at the UCLA cup (Unión Cannábica Latinoamericana); 1st prize in the “Best Shatter” category of the 2015 San Bernardino Hempcon Cup, USA.

In recent years Critical has become one of the most well-known and cultivated strains from Spain. On my holidays to the Costa Brava I regularly smoke some tasty Critical on the beach. The Skunk #1 genetics, an Indica variety of Afghani origin, is dominant in this strain. The further development of this strain is due to Shantibaba, Neville and Mr. Nice Seed Bank, who came up with the name Critical Mass. Dinafem crossed this Critical Mass with a very productive Sativa, Jack Herer (only capable of a flowering period of 70 days), and this is how Critical Jack was born. A great hybrid with 60% Indica and 40% Sativa.

Critical Jack is suitable for both indoor and outdoor cultivation. When I grow my Critical Jack outdoors, it is ready to harvest in late September. I still find it incredible, but 70 days after germination, you can harvest the plants. The plant has large light green leaves that hang down, but then – in a much shorter period of time than you would expect – there is an explosion of white flowers covered with large crystals. Under ideal conditions, with plenty of light and warm temperatures, the plant can grow up to one metre in height. Without these ideal conditions and with indoor cultivation my plant usually reaches a height of about half a metre, but the beautiful floral buds provide a high yield. Prepare for hard, tight, thickly covered buds. A bonus is that the Critical Jack is resistant to moisture and mould.

Critical Jack has a strong scent and an intensely fruity and sometimes woody flavour with hints of lemon and incense. Critical Jack has quite a strong effect. Critical Jack gives me a massive high and it gives me a euphoric and relaxed feeling. Medicinally it is used to treat pain, stress and poor appetite.
