Using NAA 00.1% on marijuana plants

A question from a fellow grower:

I wanted to know your opinion about the use of NAA concentration is 0.1%?

Do you mean α-naphthalene acetic acid? Do you mean for cloning instead of IBA? Or in combination with IBA? I have no problems with using IBA, most people do, and I don’t think NAA isn’t all that much different, although I’m not that familiar with it overall.
