Black Jack Auto is another 3rd. generation auto-flowering strain and is the product of a union of S.A.D. (Sweet Afghan Delicious) Auto and Sweet Seeds’ own elite Jack Herer clone. Growers can expect very good yields of dense, resin-coated buds. Black Jack Auto displays exceptional hybrid vigour exemplified by its very fast seed-to-harvest time of just nine weeks. It is a compact plant that grows between 40 – 110 cm. in height. This automatic plant can be grown almost anywhere although resin production will be better where there is a lot of sun. When grown indoors yields can be anywhere from 400 – 550 gr/m2 which is a substantial harvest from an auto-flowering strain. Outdoors these plants are able to produce up to 250 gr. each although excellent conditions will be required to realise harvests of this magnitude. The aroma and taste are very pungent and sweet with some notes of citrus and earthiness. THC levels are in the range 15 – 20% along with medium CBD rated at between 1 – 5%| this produces a very strong effect that is a very good balance between the indica and sativa characteristics with a nice, stimulating head high and a more relaxing physical side to it.
