So if I'm using tap water to water the plants, would calmag be a benefit to my grow?
dusto2k3 Reviewed by dusto2k3 on . Water: RO or Distilled? I'm considering either a Reverse Osmosis filtration system or a distiller to purify water for my plants as I am tired of lugging bottled distilled water home from the store. Both systems have their proponents and detractors and I would like some input from folks who use either. The RO negatives are that the filters get loaded with bacteria of their own and can actually be worse than tap water, in bacteriological terms. The detractors of Distilled water claim all minerals, even beneficial Rating: 5
