going through the first round of clones in the new aero cloner and have gotten off to a very slow start. finally getting strikes after 14 days but roots are only growing on the part of the stems covered by the neoprene puck. I actually have to peel the clones out of the pucks. (ripping off some of the new root growth) is this normal? I have about an inch to inch and half of exposed stem in the cloner. too wet down there or what? i have straight water ph down to 5.8 , 1 ml h202 / vitamin b1 per gallon of water in the rez. sprayers running 24/7. i guess its not really a problem since im getting roots, but it seems curious... thanks for the help.
