Hi all,

I am new to the world of hydroponic gardening. I started about 2 months ago with the Emily's Garden hydrogarden, and I seem to be having a pH problem. I use vinegar to lower my pH. It works in the short term, but after a brief drop in my nutrient solution's pH, the pH climbs right back up to the 7.5 to 8 range, requiring more vinegar. It seems to be "stuck" in this range, if you will, and I am not sure what to do about it. My tap water is usually around 6 pH or so.

I use pre-mixed nutrient solution called Flora Nova by General Hydroponics. Will this alter the pH of my tap water?

Is vinegar an acceptable form of pH adjuster?

What should I do?

It is - I use nothing else - but it is a weak acid and it wont work well on nutrients that are heavily buffered.
Aerating your nutrient with a fisktank bubbler will help. The air bubbles will remove the CO2-gas released by the acid.

What medium are you using?
I have yet to meet a nutrient solution that didn't lower the pH. I use GH's 3 part liquid flora series and it always lowers the pH a point or so.
If your tap water is 6 and it rises(lowers the acidity) it seems there must be something else affecting the pH. What else can you tell us about your system?

Vinegar/baking soda (calcium carbonate) works poorly with commercial nutrient solutions. Ph up and Ph down, available from most hydro places, controls Ph much better. Start there.
