Type and genetics

Jack 47 feminized marijuana seeds from Sweet Seeds are the result of crossing Jack Herer x AK47 to obtain a very powerful and productive sativa dominant plant, with intense flavors.


Jack 47 is a cannabis strain that grows very vigorously and is very easy to grow. This strain adapts well to all types of growing techniques, and it is also resistant to fungus attacks, being ideal for beginner growers who need a more robust plant.

Aroma and taste

This strain created by Sweet Seeds breeders produces sweet aromas and flavors with notes of lemon, reminiscent of orange or tangerine, accompanied by a very pleasant incense touch.


The effect produced by Jack 47 is powerful and mental, characteristically sativa. It produces a feeling of lasting euphoria that culminates in a relaxing and happy effect, ideal for enjoying with friends or at social events.


Jack 47 is known for being a high-yielding plant; it produces very large and dense buds, as well as ending up covered in a thick layer of resin. In indoor grows, it can produce up to 500 - 600g perm2, and when grown outdoors and in soil it's capable of producing really high amounts.

Flowering indoors

This sativa-dominant strain takes 9 weeks to complete flowering in indoor crops after the corresponding growth phase, a wait that is worth it for its buds full of resin.

Flowering outdoors

When grown outdoors, this strain can be harvested towards the end of October in the Northern Hemisphere and at the end of April in the Southern Hemisphere. If grown in the ground under optimal conditions and with the correct trellising, it can exceed 2 m in height.
