Spliff Seeds Description
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.

Altogether we've collected 2 about Spliff Seeds.I popped two Jack F-1 seeds and got two phenotypes. Both reached 8 feet tall, but the leaves on the one were fatter and shorter, and slender on the other. The sativa-looking plant was more vigorous and christmas-tree shaped with side branches creating a wider girth. The indica-looking plant had side-branches that were fewer in number, and her leaf morphology reminds one more of Spliff's White Widow （a "mostly indica" strain） than a sativa. See my photos comparing these two Jack F-1 phenos alongside Spliff's WW after about one month of veg, in early May.
I was puzzled at first because Spliff's states -- see Basic Info page above -- that "Jack F1 has an Indica appearance, but is definitely a Sativa." For me, that was confusing because the more vigorous plant, the one which got absolutely huge and produced the larger quantity of bud, was clearly a sativa-pheno that Spliff's did not mention. So at first I was not sure which phenotype was the pheno Spliff's had selected and back-crossed for. Now it is clear to me that Spliff's selected for what I am calling the indica-looker, designated as pheno #1 here on seedfinder.
"Jack F-1" growers will note that these phenos exist. By definition, an F-1 hybrid is a cross of two IBLs and is 50% stable. It can show variation from one individual to the next. Jock Horror is IBL, but numerous posts by Spliff's say the breeder used a Skunk F1 to produce "Jack F-1", so not all plants will have the indica look. By back-crossing with Jock Horror, the chances of getting the indica-looking pheno may have been locked in to a good degree, maybe 75% or 87.5%, depending on the number of BX.
My sativa-looker （pheno #2 here on seedfinder） produced an abundance of slightly fluffy buds （I've got 9 quart jars curing）. Her buds have some compactness -- there is a "hard" interior if squeezed -- but are slightly fluffy on the outside. A large amount of rough leaf material was also prominent on pheno #2, making manicuring messier. The indica-looker （pheno #1） actually has very tight and compact -- "hard" -- buds, which were much easier to harvest, manicure, and cure. See photo of finished bud.
There is no difference in effect as between the two phenos. Jack F-1's effect compares very well with that of the original Jack Herer, being a nicely balanced blend of stimulating and clear haze head high with a subtle and pleasant indica body buzz. When I grow Jack F-1 again, I will try to select for the indica-looking pheno in hopes of getting these highly compact buds. Compactness makes harvesting, curing, and smoking easier.
