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).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
