Went to my local hydro store for supplies and thought what they wanted for ph down was overpriced.
Hell I only pay $8.00 cdn for pH Down. That's not expensive considering,,,,,

My question: Is there anything wrong with using vinegar for ph down?
No there's nothing wrong with it. But consider how much more you will use, the more frequent use (more time) and the cost in the long run. Vinegar sold in the stores is Acetic Acid, usually around 5% by volume. pH Down is Nitric Acid. It's much more concentrated and stable than vinegar/acetic acid especially in hydroponic applications.
Quote:
If I overadjust the ph and need to raise it is there anything wrong with using Baking Soda?
Sure, I use it myself instead of pH Up. It's a lot cheaper and very stable.
Quote:
Anyone have experience with vinegar/ Baking Soda for ph treatment?
Yes read above,,,,,,,,,,,,
Good luck, spend the money on pH Down. You'll be glad you did.

ok, as far as using tap water fora ph up, that's wrong, because you are ph buffering a nutrient solution, and by adding water you are diluting your nutrient solution. the great part about a ph up or down product, is that it is very concentrated adn in a 50 gallon res. you need only use mere millilitres when adjusting/buffering the ph. And as pointed out, baking soda adds sodium which can cause a toxic build up in the soil/medium that your growing in. I strongly suggest buying a small bottle of ph up and or down, and I have always kept my ph at between 5.8 and 6.2, when flowering or approaching flowering (considering I don't veg. for very long) 1 litre of concetrated acid or base, will last a long long time, and if you buy bigger you usually get a better price, and then it will last you the rest of your life. Just be careful not to get it on your skin or in your eyes !!!!!

Hydroponic methods don't work very well in soil/less mediums. Tapwater is pH'd to 7.0-8.0 for better taste...and yes, it dilutes the nutrient solution but in a 1 gal container the amount of H2O added is ~¼ cup or less. I think the dilution is negligible. You don't have to worry about getting tap water on your skin or in your eyes!
