this is strange becuase a friend of mine is growing a plant atm, and he recently cut it in half lets say, and the plant was a good 2 feet even i'll say. he caked the cut end in rooting solution and after a week it came around fine, its still alive now at near 3 weeks after being cut. i dont know how this worked, its a female for sure, theres hairs. its just strange, becuase its seriously like just another plant now, darker then the bottem half...go figure.
