Hey there mate, so much jack out there to grow. Only one i have grown was Sannies jack. Couple where indica done in 8 weeks and some more leaning to the sativa done in about 12-13 if i recall. I would say maybe top her and spread her out and do some light traning around the bottom as this girl can really get some legs in flower, height wise. My experience was incredible smoke and high. Wish i kept the indica one around dripping in oil and the terpenes where through the roof just like the high. Odor control is a must
