Yeah I lime it. Tbsp.per cup o peat. I pc everything except the straw. I past. That. Out of 40 monos I mite lose one and that is to a spawning jar I think is questionable but still give it shot. Now I live by the rule of doubt. If there's a doubt then there is no doubt junk it. It ain't wrth the gamble time and energy

Ok, update. Advice also appreciated.

It's been 5 days since casing, and I see almost no growth. Did I fuck up the amount of gypsum or cc used or something? These are the quantities I used:


7 parts verm
3 parts coir
1 part calcium carbonate
1 part gypsum powder

This was pasteurized at 150-160C for an hour. Casing is 1/2 - 3/4" thick.

That's a lot of gypsum to use in a casing, I only use it for the sub myself. What is the consistency of that, It looks really solid. Also thats a lot of lime, i use a teaspoon per quart for peat, i hope its not too hot. I dislike adding stuff to coir for casing, its best on its own, tho adding verm is okay. Also 3/4" thick is damn thick IMO. I never go more than 1/2". Gonna take some time for the myc to work its way through.

I almost want to tell you to take that all off and just lay down plain coir. That's the beauty of coir, you don't need to add a bunch of stuff. You don't even need to properly pasteurize. Bucket and done.

I think I see some myc peeking through so it might be okay. But hold off on the gypsum and lime next time.

Awesome, thanks for the advice. I really appreciate it. I was just going off of RR's video on casing, but using 70/30 verm/coir instead of the 50/50 peat/verm. Do you think I screwed up the ratios or by switching to verm/coir I offset the pH or something?

The verm coir is fine, you can case with either or. I use straight coir and i also have used straight verm lots. Mix them as you please. My concern is the gypsum and calcium carbonate.  Those are really high ratios and also explains why the texture felt like mud. Next time skip those unless your casing with peat.  Even then a tsp of calcium carbonate per quart is plenty, use things like that sparingly if at all. Gypsum is not really needed for a coir casing either and just a pinch or two per quart is all you need if using in casing materials.

Hmmm, everything you've said makes sense. The mycelium hasn't made much progress through the casing at all. I'm quite confident with care I could remove 80% of it without damaging the healthy myc underneath. Do you think I should give it a shot or leave it and wait? Which is the less risky option? I really don't want to lose this substrate since it was looking so awesome.

A healthy culture can take a surprising amount of abuse. I say go for it.

Great, thanks for your advice. I re-cased this evening with coir. I'm optimistic - there still were no signs of contams, everything smelled right. Won't be checking on it for 3 days, I'll post pics then!

Given the history of this particular tub I would be sure to put into fruiting conditions soon, do not wait for it to get really colonized. As the sub repairs itself it will want to revert to a strong veg state and will blow through your casing really fast if your not careful.

Hey op, not sure if that's a typo but you should be pasteurising at around 65C (or 150F), not 150-160C. Temps that high will sterilise not pasteurise.

That's probably not related to the problem u were having with ur casing but I just picked it up where u described your method.

160 f will not sterilize anything and is a fine temperature to pastuerize. Really you can go as high as 170 f but I would not push it higher than that or you do risk partial sterilization. We often say between 140-160 as a safe range to be in.

Read his post again Pasty, he wrote 150-160C. As in Celcius. 160F is fine, 160C is way outside the safe pasteurisation range. That's like over 300F.
But like I said it's probably a typo.. He probably meant to write F not C..

Its obvious u meant farenheiti would think reaching temps 300degrees f. Or higher would require the use  of a heat source beyond the means of any elec or gas rangetop

The myc is finally poking through the re-cased layer. Still smells good, no sign of contams. Seems like it's taken a while, but I did put this sub through a lot. Still don't know how I messed up the casing layer mix ratios so badly, but anyhow. I patched the spots poking through and will check on it again in a couple of days. Just thought I'd give an update!! Let me know if you guys have any thoughts, especially about replenishing moisture if you think it needs it.

Like PW said, you can case with pure coir or with pure verm.  The ideal ratio of them has yet to be agreed on, believe it or not, so you didn't really screw up anything.

Your substrates look really good, except for one spot on the middle of the far-right, which looks kind of bubbly and not unlike trich.  It could just be a bad angle on some cube mycelium pushing through, but keep an eye on that.
