You mention Hydro when I specifically asked about dirt. The reason I am contemplating dirt is because it is more forgiving this is what will allow me to commute. As I intend to keep my business here.

In addition I can gain experience as I expect the law to be passed here in AZ. It passed in 1996 however they wrote the law stating it is legal for doctors to prescribe when we all know it is not.

Also realize I am contemplating LEDs which there is not a lot of documentation on. So I am taking everyone's input and trying to compare. You might call it RESEARCH from a lot of different sources.

Unfortunately unlike you I do not know it all.
