Adding Hydrated Lime to casing/bulk substrate

Hey all, I got about probably 2 qts. or so give take of pasteurized, field capacity 50/50 verm/coir mix thats been chilling out in a semi covered bucket for 2 days or so. I found some hydrated lime at the store today and want to add it to the mix. First question: how much to use? And my 2nd question is, should I PC the lime or just add it to the bulk sub, maybe re-pasteurize? Thanks

Pretty sure lime is only used in as a pH additive in casing layers, not bulk substrates.
If you are casing, you'll want a pH gauge of some form, and the amount you use is the amount needed to get to the proper pH, which I'm not sure on because I don't case, but I'm sure you can easily search for this number.

Yes Ryath casing layers is what i think i meant, thanks. So if I wanted to go mono-tub with my 5 qts.of spawn, I would not need the lime? I am currently double end casing 50/50 pie tins in a shotgun FC with good/gooder results, but I usually chuck em after 2 flushes cuz I'm scared of that green bastard! Thanks!

I think you are getting your terms a little confused... You might be talking about layering your substrate/spawn into your bins/tins, which is one way of doing it. Another way is to mix it all together then top it off with a final layer of substrate to be sure no spawn/grains are left exposed. Either way works, but I prefer to mix in the hopes that the amount of inoculating points is increased.
A casing is a thin (1/4" - 1/2") non-nutritive, pasteurized layer that goes on top of the substrate after colonization to provide a humidified and moistened microclimate to further induce pinning. I think the standard one is 50/50 peat/verm with hydrated lime and gypsum as pH buffers. It is not necessary for cubes at all, but some people swear by it and won't grow without one.
If you are just getting into bulk projects, I recommend skipping casing and getting the basics of pasteurizing, spawning, and fruiting conditions first. After you see how that all rolls, you can decide if you want to try casing.
hope that clears things up

You could add hydrated lime to your bulk sub, but it really isn't necessary. The purpose of the lime is to raise pH to 7-8 so that trich spores do not germinate and ruin things. With a bulk sub like coir, the mycelium colonizes it so fast that trich never gets a chance to set in anyway. Casing layers are adjusted because the mycelium doesn't colonize them, and so it is susceptible to trich. Cubensis does not need a casing layer for good results.

no lime in coir/verm
only in peat/verm or w/e casing layer you choose.

Also, never add lime to already damp casing mix. If you've already moistened it, put it in the sun for a few days to dry and then add the lime before re-pasteurizing.
Never add lime to bulk substrates. Mushroom mycelium prefers a pH of 5 to 6. RR

No sir, he's talking about merely "casing" grains in pie tins for fruiting, not referring to spawning to a bulk substrate in the old tongue using the word "casing".

Solid advise.

If you're using verm/coir, simply mix it thoroughly with your spawn, and then when colonized, fruit as-is, uncased. Don't use lime. RR

I add lime to my bulk straw for soaking it in it basically get's rinsed away though. I also put hydrated lime in my poopoo lol I never had a problem I don't use a ton though I also add lime to my casing it's already in the casing mix I use.It makes it hard for bacteria to survive it's ph too much is bad though just like anything else.
