Blend the two cannabis staples of Critical Mass and OG Kush and out comes the indica strain of Critical Kush. The strain variant has aromatic notes of earthiness and that triggers a calming sensation relaxing in the turn the mind and body of the user. Critical Kush is said to have a staggeringly high THC content along with a very moderate level of CBD. The strain thus becomes medication for patients, especially at night to get relief from symptoms of stress, pain, insomnia and muscle spasms. Flowering cycle of Critical Kush generally involves a period of 50 to 60 days. Growers cultivating the Critical Kush very well wait this period to help the flowering phase achieve completion.
