Lemme ask ya a question.. Ya got a sec? Did you know you were gonna grow Jack before you started this venture? That's 2..Opps.. Playin' round with ya.. That jack will stretch something feirce. That tube light is just getting it taller. If I were you at this point.. And I knew what I now know.. I would lean that baby over and scrog. The reason I say this is because Jack it a touchy strain. It's gonna get tall and the scrog would keep the height at bay. Take a cutting after you have started training her,and she's all vegged out nice. You'll wanna be keepin' that strain! I promise...
