Cinnamon aroma and sweet and spicy flavor. Huge resin production. Massive budding beast. Soil or coco is ideal medium. Medicinal strain. Longlasting, cerebral high with a nice body buzz. Potential THC level high. Jack F1 is a Dutch crossbreed between Northern Lights, a Skunk F1 and a Mexican Haze. She is the result of a long and arduous selection process to obtain suitable phenos as parents. We took several generations of thorough back-crossing to her original parents to stabilize the strain, allowing further generations to pretty much give identical offspring. This resulted in our Jack F1. She is a 75% Sativa plant with extremely high THC level. Jack F1 has an Indica appearance, but is definitely a Sativa. However, with a short flowering period. Jack F1 is covered in snowy crystals of resin from top to bottom. Stick to advised nutrients, donโ€™t overfeed. Especially during the vegetative period (4 weeks) keep nutrient levels at a minimum. Keep her on a 24/7 schedule during vegging, to limit height. This advise basically goes for any Sativa. Preferably grown in soil or coco with plenty of space. A Sativa dominant plant she will form one giant main cola, so donโ€™t prune her. Smell is sweet, spicy and slightly cinnamon. The taste is sweet and spicy with a touch of haze. A longlasting cerebral high and body buzz. Classic Sativa high. Highly medicinal strain. Medicinal value: Add, adhd, anxiety, arthritis, cramps, depression, inflammation, insomnia, loss of appetite,migraine, pms/pmdd, pain: muscle/joint and neuropathic pain.
