XJ13 is my favorite strain to wake up to.
I feel alert, calm, and in a great state of mind to start my day. I'm able to execute my tasks while feeling clearheaded and invigorated. I tend to prefer my dispensary;s 3 pack of 0.5 gram preroll because a little bit tends to go a long way for me.
This strain reminds me of Mr. Clean's (another Sativa-dom) focus-lending properties and being that know-it-all kid in kindergarten class.
