Critical Jack Auto is a the feminised autoflowering version of Dinafem's hugely popular Critical Jack, a top-quality hybrid aimed at cannabis connoisseurs.

To create this express-flowering version, Dinafem have crossed their elite Critical Jack clone with Roadrunner, their fastest autoflowering genetics, resulting in a vigorous and easy-to-grow plant that will leave growers and smokers highly satisfied!

Critical Jack Auto is ready to harvest just 70 days after germination, it produces a heavy crop of surprisingly long, dense buds with great resin coverage and has a complex terpene profile, with intense and alluring aromas of incense, wood, lemon/citrus and exotic spices. The effect when smoked is potent, with a balanced physical and cerebral sensation, giving way to a relaxing body stone, it's a great choice for relaxing and socialising in good company.

Ideal for indoor growing where space is at a premium, Critical Jack Auto also performs very well for discrete cultivation outdoors on balconies or in greenhouses, and in a mediterranean climate, several crops a year are possible. It is a medium-sized plant with high resistance to pests, pathogens and high humidity conditions.

Critical Jack Auto is a superb plant for beginner growers and for anyone who wants to have an early summer harvest of tasty top shelf buds.

Hi Thibaut,

The discreet shipping option includes re-packing your seeds in another container, much safer to go through customs. The name on ypur bank account will be "AW".
