Product Details

Jack F1 is a crossbreed from Holland. Her parentage is Northern Lights, a Skunk F1 and a Mexican Haze. She is 75% Sativa and her genotype is Skunk #1 xNL xMexican Haze. It took a lot of time and care to select these phenos - several generations of thorough back-crossing to her original parents stabilised the strain which allowed later generations to produce almost identical progeny.
And so a plant that looks like an Indica but is definitely a Sativa with an exceptionally high THC level was born.
With her lovely scent of cinnamon and a taste that is which is sweet, hazy and spicy Jack F1 also produces loads of resin from the masses of buds that cover her over her short flowering period. Due to her Sativa dominance you will find that she will produce one massive central cola so pruning is not recommended.
Grow her in soil or coco and adhere to using the advised quantity of nutrients. Avoid overfeeding particularly during the four week vegetative period of four weeks. A 24/7 schedule during vegging will restrict her height.
Jack F1 givers an enduring ‰ۡÌÝÌáhighbrow high‰ۡó» and a buzz to the body, a typical Sativa high.
Jack F1 is also very useful medicinally. Use for ADHD, anxiety, arthritis, cramps, depression, inflammation, insomnia, loss of appetite, migraine, PMS/PMDD, muscle, joint and neuropathic pain.
