Wity I promise you on my plants lives you will be best on water and soil hand on heart, I asume you grow small and for personal,, the money on A+b etc spend it on another light and the power bill and increase the grow space half the wattage. That is the Key mate not any of this fancy bottle shit dude,, What you growing under? To get rid of hard water is just a 99 pence sachet from wilkinsons away or a 1 off ro unit and no more hydro shop runs..
