hey stinky
I was wondering what household and/or organic materials can be used too safely raise and lower ph. I have heard baking soda too raise it.someone told me vinegar to lower it. are these correct and do they work without harm?
are there other things that work. ty

ps: I have been searching the forums for threads on water.
I haven't found any yet. my tap water comes out very green in test.
also guy at hydro shop said chemicals in tap water will kill micronutrients like earthjuice micronutrients.my available water sources are: tap water/bottle water/distilled water/ reverse osmosis water/ creek water. which would you recomend I use? I am thinking I should use the creek water, could I run into unforseen problems from the creek water, it does run pretty fast so its not stagnent water. thx for any light you can cast on these subjects
