Critical Jack Seeds Information

The Critical Jack is a cross between the high yielder Critical Mass and the THC stunner Jack Herer. This results in a hybrid strain that brings out the best of both strains. This strain has won several cup prizes, namely: in 2011 first place for outdoor cannabis (Canna. Cup Thai Maria) and in 2012 third place for outdoor cannabis (THC Cup). You don't become a Cup winner just like that and this also shows that she is one of the toppers within the cannabis seed industry.

Growing Critical Jack seeds

This cannabis plant can be grown indoors and outdoors. Indoors she comes into her own in a SOG setup, her plant structure is quite compact and does not take up too much space. It is also possible to scrogg her, the plant has a good height for this and grows in the fairly wide area which is handy to start a big SCROG. After a short flowering period of 8 to 9 weeks, she produces bright green buds covered in a sticky layer of resin that sparkles with trichomes. This strain can be seen as a commercial indoor weed or can grow into a large Christmas tree outdoors.

Medical and Effect Critical Jack Seeds

Consumers of this cannabis strain report that they have benefited from headaches, depression, anxiety and appetite. The effect is balanced and is accompanied by a psychoactive push, because of this she is able to relieve pain in addition to mental aids as well as physical aids such as pain. Because the THC content is above average, the effect will last for about 2 hours. You can get an uplifting feeling that later turns into a numbing effect on the body. Recreational users indicate that the effect lasts for a long time and encourages you to socialize. It is possible to consume this cannabis in the morning or during the day. Unlike many other cannabis strains that result in a couch-lock, the Critical Jack keeps you active due to its energy-boosting effect.
