The method is crucial during the vegetative stage of your Black Jack Feminized seeds.

Low-stress training involves bending the stems of your cannabis plants to control their growth. The technique is beneficial when growing your Black Jack Feminized seeds indoors, where space and lighting may be a challenge.
