I was a little surprised as well. I have been trying to find the exact blog/web page that I read it but to be honest I have been trying to reaearch several MJ companies and I don't remember which one I found it on.
I did find several others pages though that reference needing a license to grow but then needing a seperate license to sell. I am not sure if that is the difference between stages 6 & 7 or if selling is a different licensing process entirely.
