Jack F1 is a specially bred cannabis seed that combines the genetics of Northern Lights, Skunk F1, and Mexican Haze. Spliff Seeds went through a meticulous selection process to find the best parent plants, and then spent several generations stabilizing the strain to produce consistent offspring. Jack F1 is a 75% Sativa plant with a high THC content, despite its Indica-like appearance. It has a short flowering period and is covered in resin crystals. When growing Jack F1, it's important to follow recommended nutrient levels and not overfeed, especially during the 4-week vegetative period. It's best to keep the plant on a 24/7 light schedule in order to control its height. Jack F1 thrives when grown in soil or coco with ample space. Pruning is not necessary, as it will naturally form one large main cola. The strain has a sweet, spicy, and slightly cinnamon aroma, with a taste that is also sweet and spicy, with a hint of haze. The effects of Jack F1 include a long-lasting cerebral high and body buzz, characteristic of a classic Sativa. It is also highly regarded for its medicinal properties, as it can help with conditions such as ADD, ADHD, anxiety, arthritis, cramps, depression, inflammation, insomnia, loss of appetite, migraines, PMS, and various types of pain.
