I took Bushdoctor's advice and did the daily flushing, except with Olivia's cloning solution per bottle instructions and I'm getting roots in 7 days on average.
I've found three major advantages to using this method.
The first is the cost, you use the coco you were going to grow in anyways, and perhaps some cups and a heat mat.
The second is the ability to root rather large clones that fill the cups with roots within a day or two of initially showing roots, with no noticeable time penalty in the initial rooting.
The third, and in my opinion, most significant advantage, (especially over aero/bubbler cloning) is the elimination of bare-root-to-medium transplanting. My clones could take an extra week to root, and it would still be worth the stress-advantage over similar hydro-cloning methods.
