Hey Faded,if your Ganny dont know nothing bout growing ,try mixin her up a batch of a fair TLO mix n let it cook for 2-3 months and tthen you have a far superior soil that'll get you further than this stuff.with a water only method.just food for thought.in the long run it'll last ya longer,its cheaper and beter meds and easier to use.Just my opinion ofcourse but few soils work awesome straight from the bag unless your using nutes to excel them to a point."My 2 cents" :tiphat: or teas which are way better.as far as a health issue if that the case.
