Critical Jack is one of the most popular strains of cannabis in Spain. It has drastically increased in global popularity in recent years as well. Skunk #1 provides the strain's dominant genetics. Some of the best traits of Big Bud – a wildly popular Afghani indica – are also evident. Critical Jack has been bred and distributed under other names like Critical Mass, but it has seen various changes and enhancements through various hybridization projects over time. This auto-feminised variety developed by Dinafem uses the classic standard Critical hybrid and crosses it with specific in-house genetics. The final result is a plant that beats out any of its ancestor strains by a wide margin.
A primary advantage of Critical Jack is its flower time: about 70 days on average. It can even be harvested at around 60 days with nearly the same potency level. The plants will require some space to stretch along with ample, consistent lighting in indoor grow environments, and they respond well to various growing methods like SOG and ScROG. This strain is also a perfect selection for greenhouse growing. When cultivated outdoors, Critical Jack favours warmer weather. It should therefore be harvested between late-September and mid-October in the Northern hemisphere.
Critical Jack delivers a relaxing and head-filling effect. Its sativa genes make for an invigorating euphoria that has practically no ceiling. Mature plants take a good bit of their appearance from their sativa genes, having tight, large dark-green leaves with numerous flower sites. Their buds sparkle with a dense coat of potent resin. The plants also present a well-balanced ratio of leaves] to flowers. The aroma is similar in smell and intensity to Skunk #1 so those growing Critical Jack indoors need to provide a well-ventilated space with a good air filtration system.
Please remember that the growing of cannabis plants and the cultivation of seeds is illegal in some countries – please check the laws of your country and don’t be growing any plants if it is against your country’s laws.
