vinegar can be used to lower ph
 

I realize vinegar can be used to lower ph but can it be toxic to the plants and does it work as well as
the general hydroponics ph reducer (phosphoric acid). Thanks MS

The problem with vinegar is it's not stable and won't hold your desired pH for very long so by adding
more might harm the plants.
By all means use pH reducer formulated for hydroponics. Theirs is no cheap easy way to grow
hydrponicly.
