Jack F1 Feminised Seeds (Spliff Seeds)

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, don’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 don’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.
