not experienced, but first run went good, all rooted eventually, it's not fast process, second run 1 rooted and rest got a ball of slime on the ends, trashed, bleached, cut 3 more and they're in there now, waiting to see what happens. groclone recommends using nothing except cutting and putting into ph ready water. so im letting the olivias sit this time and see what happens. im changing the water ed or eod also instead of 3 - 5 days. the ph has fallen back out of range by this time anyways to 7.6 to 8.0
