Juciy Roots = 0.1% 3-indole acetic acid, 0.03% vitamin b1 (Thiamine mononitrate).
I have a botanicare areo cloner that I get nearly %100 success with however, the fastest I can root a clone is by using Shultz Takeroot and place them in a soil plug made of Subcools super soil. For some reason the combination is ideal and starts the roots faster. I then take the plug and place it in netting as to keep the soil together. I place the plug in a hole in the cloner and it shoots them out the bottem in a day or two everytime. I do use a rooting mat for added heat to both. I have done three tests of 10 clones for each method and came out with the same results each time.
My clones done this way get the fastest growth rates from the start as well. (a multitude of combinations were made to test the theory). Yes I still use the soil plug clones in hydro applications.
In the old days, we would use Nitorgen, Phosphoric Acid, and Potash to create our cloning solution. We also knew about B1 in water as a good start... Look how far we have come.
My rooting tip: Fim/top the branch a few days before taking it from the mother as a clone. Might be surprized!
