i would imagine it would be better unless you have well water and that is just rain water from the ground... my water has a clean taste and people buy water in bottles all over the country from this aquafer... but rain would prob have less trace minerals... get a good deep well IMHO is the best other than RO water. but with RO i would have to worry about trace shat thats already in what i got...
and i only say that for soil grows not hydro... i dont know shat bout hydro
