KS is alright, but check out something like the TLOsoils.com master mix or the buildasoil mixes as an alternative before you commit. Mix up a big old batch for 12 plants pretty easy with the right kits. Still having mixed results with my noobness, but even better results with the TLOSoils kit than I did with the KS in my opinion (though your mileage may vary). :smoking:
