S. -

I am waiting for the Convention where we will have a talk about PH by one of the experts in water from USGS - Dr. A. Brigham.

You can adjust the water you use for watering. If it is too alkaline - people use white vinegar, if it is too acid - there is a Dyna Grow ProTekt thing. But you need to test PH of your water with fertilizer to figure out how much you need. And I bet you need to test it in winter, summer and spring - because the numbers can be different because of a difference in precipitation in your area.

Your PH water test is usable, have no idea what aquarium PH adjuster will do to your plants.

Did you that mean?

It is it.

If the house water is particulary bad, and especially if people grow orchids, they install Reverse Osmosis systems to clean the water - the result is close to distilled water. After they add fertilizer to it - it goes acid - so ProTekt fixes the Ph and adds necessary elements.

I am not promoting a RO system because it only makes sense if the water from the tap is plain awful - or if you are growing super sensitive orchids.
