I have 99% success rate or better I rarely lose one of 50-100. My friends too. They do it exactly and get the same and they r newbs 2.
Hey try advanced nutes root shooters I am a good cloner but now cuz of them and I cut my clones put in water for an hour or so just no longer than a cpl days. Then cut again fresh. Then dip in cloning gel I use rootech but advanced juicy roots is so good u can't buy it without a med card in us. So I get that in Canada. Dip put it hole an put a dome on under fluorescent light for about 6-7 days and boom roots everywhere. I have cloning machines and dont work this good. My old way in peat pellets or rapid rooters not even close. Try them and follow those steps n u will maybe lose 5 of 50 tops good luck.
