+1 on the SIP. Mine worked extremely well last summer - problems with the grow were not the fault of the SIP.
Lots of designs for SIPs including easy DIY. I used this design

If I used the planters for weed again, I would change two things. First, I would mulch either with plastic as the earthbox does or with other dry mulch material, and second, I would let the reservoir empty completely for a while before re-filling with nute solution. My soil stayed too moist because I did not let the reservoir dry out, leaving the soil surface moist most of the time, resulting in or at least encouraging the evil gnats.
SIPs work really well, so don't hesitate to try them out. Large ones like I used should work really well with LOS. Mine worked fine with pro-mix and three part nutes. Good luck with your grow.
