You are confusing acidic with soft, those two conditions are not related. What I mena is that if you take a plant from a soft water area, say two specimens from same spot. Put each in a separate container side by side in identical light conditions. In one place hard water, in the other soft. The plant with hard water will grow better than the one with soft. This may not apply to every plant (nothing is universal), but I am betting it works with the majority. The hard water generally contains CaCO3, at least our does. This makes for great growth. I use zero Co2 in my plant takes. I would hate to see them if I did, I can hardly keep up with the growth now! --- David Sanchez <barbax2@yahoo.com> wrote: > > "The plants will lower the conductivity, but you > will > not have much luck if you start the plants in soft > acid water.
