Can someone refer me where to look for info on PH.
For example, what I need to know to achieve the right ph for my casings.
I need to know how to test ph & what not.
Any good links?

Roger Rabbit said: Actually, gypsum contains calcium which raises pH, and sulfur which lowers pH, resulting in a buffer that prevents wild swings in either direction.
We use lime to raise the pH only for the reason that mushroom mycelium is more tolerant of a high pH than mold mycelium is. Both mushroom and mold mycelium grow best in a pH of around 5.5 to 6, but since mushroom mycelium can tolerate the higher pH, we do that so our casing layer favors it over molds. I use 1 teaspoon of hydrated lime per cup of peat. Don't figure the verm when calculating lime. Use gypsum at 5% to 10% by volume of the amount of peat. In other words, for ten cups of peat, use 1/2 to 1 cup of gypsum. As said above, always mix the dry ingredients first, then add water.
Gypsum, as I said, prevents swings in either direction, but the commercial growers long ago realized that it also increases disease resistance and also increases the size of the mushrooms by providing valuable trace nutrients and minerals. RR
Lime is used to raise PH. It needs to be around 7-8.

Sorry to double post, but I'm leaving and I gotta hurry and write this.
You can buy PH strips at walmart that will do you just fine. There are digital ones, but there is no need for them. You mix the stuff in with your casings to raise PH.
