ive never seen ph in a mush grow, is it supposed to be neutral?
6.8 - 7.2 is optimum - PH is a very large factor in the proper growing of mushrooms. The more basic the better as a general rule becuase there metabolic processes make the substrate more and more acid until finally the substrate is the perfect PH for competitor molds - which is usually why you will begin to see Trich late in the 2nd or late in the 3rd flush - this is why you want to put some quick acting basefying ingredient in your casing and also some slower acting leachant in there as well- that is if you are intent on 4 or more flushes or want to guard against trich. Long ago I simply opted to quit at flush 3 and battle the trich as it came up rather than put oyster shell and such in my casing but I've been known to really bruitalize my casing with strong base substances even to the point of inhibiting mycelium for the opening flush - I really don't know if I gained any advantage.
