critical jack marijuana seeds

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.

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 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.

Critical Jack by Dinafem has been awarded 1st prize in the Best Shatter category of the 2015 San Bernardino Hempcon Cup, USA, thanks to the extract elaborated by Cracker Jack Extractions

This outstanding genetics boasts incredible potential, fully satisfying experienced growers and beginners alike. It grows into a wonderful, fast-flowering, easy-to-grow, vigorous, medium-sized/big marijuana plant that yields large compact buds brimming with resin. It shows good resistance to moisture and pests.

Characteristics of Critical Jack cannabis seeds

Critical Jack cannabis seeds by Dinafem belong to a Sativa-dominant feminized cannabis strain obtained by crossing a Critical + and a Jack Herer, which gave us a top-quality hybrid aimed at connoisseurs.

Critical Jack cannabis seed grows well indoors, particularly in SCROG, provided you monitor its size. Outdoors, it performs best in a temperate/Mediterranean climate or in a greenhouse. It is a well rounded marijuana plant that truly deserves a place in every garden.

The flavour and aroma are intense, with clear notes of citrus fruit, incense, exotic wood and spices. The effect is long-lasting and rather cerebral. It is the perfect cannabis strain to have lively debates with your friends.
