where to find pH buffers for casings?
    #1727704 - 07/18/03 03:14 PM (14 years, 4 months ago)

i can't find crushed oyster shell or limestone anywhere.... i've been to every gardening store and nursery in the area. none of them carry it...

where might i find some, and just how important is the buffer really when using a casing made from just coco coir and vermiculite (no peat)?

Coir is slightly acidic, so it won?t hurt.

Joshua was talking about this somewhere in a post recently. In the case of coir you are not using it to adjust the PH because of the substrates acidity like with peat. It counteracts the effects of acid that the mushrooms create as they gorw I believe. I am not to clear on this, so I may be a bit wrong about exactly what he was talking about. Wish I knew which post it was.

it's joshua 101,and there's rly not a big problem with the acidity when just using coco coir and verm.
SKAKTA was on the right track thou the mushies produce a piss that will in time make substrate more acidic.

look at lowes or home depot if you can.and IME use lime or oyster shells
thier longer lasting,so it'll work against the shroom piss which is produce over time.

My friend buys his at a farm feed store. The pH of his coir/verm casing mixture is usually pretty close to 7 so he does not bother with lime, but the addition of oyster shell helps keep the pH stable over numerous flushes.
