OK my MMJ stock guru's, which other tickers will be good long term investments to get into within the MMJ field: Looking to invest about 10k

I have SKTO
AEGY
CANN (limited #)

I want to invest and not flip. I am looking at 3-5 years.Was looking at the PHOT/MJNA but before I start my DD want to know what you all are thinking is worth while. 

Thanks in advance to all. Hoping SKTO can leverage off of AEGY next week with beta testing on PJ site.
