Critical Jack – Dinafem Seeds


Critical Jack is a feminised cannabis seed deriving from the cross of two cannabis legends: Critical + and Jack Herer. At Dinafem Seeds, they decided to work on these two genetics because they thought that crossing them would lead to a really good thing, and that’s what happened. They’ve masterfully mixed the traits of both genetics until the three legendary families (Skunk #1, Northern Lights and Haze) within this strain became evident. In a nutshell, a high-class hybrid that deserves a very special place in any garden; an amazing reputation earned for her yield, potency, taste as well as for the incredible extractions that can be made out of her super-tasty trichomes.
