Well Promix and Fox Farm ocean soil and light warrior worked really well for me and I will continue to use them based on my experience. Easy to flush and well balanced. Mg on the other hand lets little flies in my house. Seems they don't irradiate or kill off things like that, at least that has been my experience. I do think keeping things simple is best and you can always run two different soil setups and test for yourself. soil from Fox farm or where ever is not that expensive when you look at the hobby as a whole. Money is no object for the man in need of good weed.....:hippy:
