One of my cuttings from last week has shown root bumps two days ago, and now there are nice 2" roots in those spots, but last night when i came home i noticed that the root bumps were starting to form above the neoprene disk that hold the cuts in my aerocloner. im wondering if i should just adjust the clone, and put that portion of the stem below the neoprene disk? there is already an inch of exposed stalk below the disk inside the aero clone machine, with plenty of roots forming. any help is appreciated, and i have tried searching to see if anyone else had this problem, but i came up with nothing..maybe i just need to learn how to search more accuratley though... edit: i was wondering why this happened, but i think i know, i mixed dyna-gro rooting concentrate liquid into the aerocloners water supply, maybe next time ill just dip the cut, and put it into plain water with superthrive instead of dyna-gro KLN rooting concentrate
