PH Down is pretty easy to make but is anyone making their own PH Up? I don't really like the idea of baking soda (it works in a pinch) but not sure who locally would carry Potassium Hydroxide.
Edit: No, there are no hydro or grow shop with in even 150km of me![]()
You could possibly use sodium hydroxide (lye will be this or potassium hydroxide) which is available at pretty much any hardware store (if you have one).
