you want a balance of both for growing, although most tap water is pretty hard..depending on where you live. hence the reason you get a water softener for your house.. it softens the water with salt, can't remember the name of it..

I leave my water for at least 24 hours to evaporate any chlorine in the water.. you could try the same?
