No problem, glad to help. If you really want to get the most of the peat, it is best to use it in some cilinder and slowly drop the water over the peat. Do not use just pure RO water, add some tap water just to get to like 5 ppm or so, this way you get some ions that the peat (or the humic acids more precisely) will exchange for H+ and you get more acidic water than if you are only leaching the substances out. Also if you are preparing the extract, use tap water to do so, it will have the same effect. You should be able to get to pH 4 or sometimes even lower without adding some anorganic acids. But I never tried any granules, so I can not promise it will work this well. 🙂
