we don't use soft water because plants need it, but because it is more convenient when RO is used.

Controlling stable level of KH with chemicals is not easy task. Too many variables, too much time and work. So why not let the water stabilize naturally on it's own. I tried and it seems to be working just fine.

Yes, plants need Calcium and Magnesium. When Calcium test kit reads bellow 20 ppm Ca2, I dose CaCl, CaSO4, Soda and MgSO4 premixed dry in the right ratio Ca:Mg:Na.

Thank you,
Edward
