I have had 100% success with aero: I use a cheap cloner.. View attachment 1501918 under $70us.. (DIY lid ) I use Plain, non PH'd tap water ( my ppm is in the 500's) no hormones, or additives ( a few mils of Pro-tecT & KLN works well but not necessary ) no domes, no MISTING, no heat mat 76 〫 f T5's For me, I find as long as I use a healthy mother & clean tools & area. and don't fqu with for a couple weeks 100% roots. I had bout 95%+ with rapid rooters/ ready rooters but am away from grow too much and can't keep misting dome and chking moisture of plugs. also LAZY.... so aero is the way for me a few pix of last batch 6/14 jus my .02 ✌ bob....
