Need Input on RO Water Test Results
I have a four stage HydroTech RO water filtration system which I use for watering my orchids as well as drinking water. It has a sediment filter, two activated carbon filters and a RO membrane filter. I recently replaced all of the filters and obtained the following results with ditigal testers.
Raw Tap Water - PH=7.3, Total Dissolved Solids=235ppm, Conductivity=413us/cm
RO Water - PH=6.2, Total Dissolved Solids=33ppm, Conductivity=57us/cm
Can anyone tell me if my RO Water test results are good compared to my Raw Tap Water? Should my RO Water test results be better considering that I just installed new filters in the system? Do these test results indicate that the quality of my RO water is good for orchids?
Any input that you can provide on the subject would be greatly appreciated.
