The Rootone is a powder and I think they now have a liquid out. I know the powder is in almost all the gardening centers. Walmart, whatever... Kaotic said it right, there are a hundred brands of the stuff. Just do an online check of the nearest store to you that has a garden center. I think they all sell it.
Each has it's own instructions, again, just like Kaotic said.
On the resources page is a thread on cloning by "hick" just sub potting soil for seed starter or perlite. It will work just might take a day or two longer to show roots IMO
