These feminized photoperiod seeds develop into impressive, tall plants that reflect their sativa dominance. Because they are feminized, you can dedicate your full attention to the flower-bearing females, maximizing your canopy space and resin production.

Critical Jack is known for her rapid development, featuring a vegetative stage that lasts between 28-42 days. She has a tall harvest height and a sturdy structure, though her vigor may require some management in smaller indoor spaces to keep her reaching her full potential.
