Hey Tip,

Hope you're working this out.. here's my $0.02..

Ph in cloning should be about 6.3.
Water temp 75 degrees
Nute strength (flowering nutes) 300-400 ppm.
Miminmal light. I use 1 t-5 tube flouresent in a 4' panel.

I've recently started using an aeroponic cloner and honestly, it's working but doesn't seem to be much faster than using an old school method. What makes you feel better is popping off the top and seeing root growth. You don't see this with rock wool or rooting cubes until the roots protrude through the medium..

In either I have a +95% success rate, the clones generally look like shit on top.. Yellow crappy leaves.. Once they root and you replant, they take off.

Peace, Farmer Rich
