Black Jack®CBD-rich clone from Diesel ancestors
Productive CBD strain.
CBD-rich version of one of the first and most appreciated strains from our seed bank. Black Jack CBD® is the resulting hybrid of the cross between our Black Jack® and a selected CBD-rich clone from Diesel ancestors.
The THC:CBD ratio of Black Jack CBD® stands between 1:1 and 1:1,5, making it a strain rich in CBD (Cannabidiol).
This is a quite productive strain with a very strong structure, typical of Indica-Sativa hybrids. The plants develop a big main cola and side branches capable to hold multiple buds of a good caliber. The aroma of this strain is sweet, with a touch of incense and fresh lemony hints.

Black Jack CBD Feminised Seeds
This blackjack cbd has great flavor but was extremely leafy.
I did not get the same pheno in the picture out of 10 cracked seeds.
To much leaf for this guy but it would make great extracts.

Black Jack CBD Feminised Seeds
I was using Natural Spring Water. Unfortunately the PH was super high. I Started correcting the PH of this Spring water, and now the Black Jack sprouted fast, and is growing strong with the others.
One thing I can say, is that it is more sensitive to PH than the others that I have grown with this water, but otherwise is a beautiful seedling.
Assuming the PH was ok was detrimental to these seeds, and my whole garden suffered from it.
Will update at a later date.
