Ok i am soon to be trying diff casing meathods and mixes, and i was wondering when u do a 50/50 verm/moss mix is it 100% necessary to use oyster with it? of can u just use the 50/50 without the oyster and be fine? and also this will be done with broke up 4oz cakes

I use 50/50 with no additional amendments and it works just fine.

I recommend hydrated lime. It's water soluable so goes to work right away when you need it. Try using gypsum at ten percent the amount of peat, and hydrated lime at one teaspoon per cup of peat. That should get you in the ballpark, where you can check and adjust final pH as needed. Shoot for pH 8. RR

I would leave the cake alone and case it that manner. 50/50 will work, but you are always better off neutralizing the acidic nature of peat.

but see thats the thing this is going to be my first casing and i don't wanna start off with measureing ph and stuff. i just wanna try to make a quick basic casing that will work with like i said just peat/verm 50/50, also im going to make a test one of just verm/pearl like dontplay is in the process of to get the feel for it.

If this is your first casing and you don't want to mess around, Go get the damn lime or gypsum and neutralize the acidity. Done.

I don't feel like messing with pH, so I don't, but I don't usually keep anything for more than a flush or 2, either.
When I have, however, it doesn't seem prone to contaminants.

Yeah or you can just buy some jiffy mix from wally world or a garden supply store and you won't have to mess with the PH. In my honest opinion after my little cake casing thing is just leave it as is. Start some jars of grain and then plan on a casing.

They say Miracle Grow Moisture Control works good for casing too. No need to worry about pH adjustment. But it's so easy to do a 50/50+.

yea i was thinking about buying a 5lb grow bag of rye grains and knockin that baby up. then making 5 1lb casings of 50/50 verm/peat without any oyster. and just use the grains. would that work?

I used mgmc and it worked good, but I got green most of the time. Switched to 50/50+ and used RR 1 tea spoon per cup of peat and 20 large casings later not had any green. The lime makes a good contam barrier.

If you don't buffer the peat. your pH will be way too acidic, and though the myc won't mind that much, the contams will love it.
Trich loves acid, and grows much slower in alkaline mixes, and very fast on straight peat.
Oyster flour is easy to use.
But yes, you will have success without oyster perhaps.
Let me tell you this though, most noobs take shortcuts suggested by masters, thinking they don't need this, and they don't need that, and sure, many of those projects will yield fruits, but how many, and of what quality?
Just because a fruit grew there does not make that place ideal.
Best advice is to follow old hands to a tee, without deviating until you master it.
It's like gypsum, you don't need it, but some swear by the harvest that it is essential to good yields.

This is not true imho. From the book "The Mushroom Cultivator": "Peat is highly decomposed plant matter and has a pH in the 3.5-4.5 range. Since this acidic condition precludes many contaminants from colonizing it as a substrate, peat is considered to be a fairly clean starting material. Because peat is too acidic for most mushrooms, the addition of some form calcium buffering agent like limestone is essential".

Agreed. Peat should be buffered. Mushroom mycelium prefers a pH of 5 to 6, so at least some buffering is suggested. Normally, we buffer up to pH 8 because mushroom mycelium can tolerate the higher pH, but it ruins the day for most molds. RR

i think im going to use this for my 50/50 verm/peat, in which im going to steam the 50/50 anyway so that should clear it from some contams or should i just mix my verm n peat and add water with hydrated lime? if so how much hydrated lime and where can i find it and what kind?

Mix the dry ingredients first, and then add water. Pasteurize for one hour at 140F to 160F. I gave the amount of hydrated lime to use in my post above. Check garden centers for the hydrated lime. A few sponsors here also have it. RR

ok well when u say pasteurize im not sure what u mean. i havn't read really anything about pasteurizeing. can't i just put the amount i need into 1-2 8 oz mason jars and steam it? then when it's done let it cool for a couple hours then make my first layer in the tin then my crumbled up cake then my thin layer of the rest of the mix.
