I haven't been seriously culting cubes in uh, a long time. So I'll leave that to the cube growers.

As far as 'pans' go, they're a genus, not a species. So there's different requirements for different species within the genus. For me, cinctulus for example performed best on just horse dung, or horse dung with straw.
I assume you refer to Pan cyanescens.

So. The verm. AFAIK about 2/3 coir, 1/3
dung / compost / w/e is pretty much the norm. I don't know if you refer to subs or casings, but that seems to be 'average' for subs. It would seem practical for deeper subs to keep an eye on aeration, I can see clear advantages for verm there, but don't think anyone would prefer deeper subs with these?

Grabbing a chair for the rest. I've been wondering about old craggy tubs for quite some time. It's probably, indeed, the spawn that matters. On the other hand I've killed off a series of tubs by casing with verm straight from the dumpsterdived bag. Everything triched. Then I filled a jar with some verm, put it in the FC and it grew trich too ... So yeah. Environment does something I guess, even with great spawn. But assuming there is no nutritious shit in your coir or verm, nothing should be able to grow in / from it.

This is something that should be the case with verm. Everyone knows how much sand, stones, leaves, seeds etc are in coir. Really interested what other have to say about this

^ yeah, that's something as well, it's never the coir, and the coir doesn't matter...

BUT then sometimes there are sticks, pieces of ribbon, pieces plastic in the coir. Larger coconut husk pieces. Visible salt crystals, indicating a salty mix not washed enough. Most coir is made from stuff on the ground in south asian coconut processing plants isn't that right?

Any of those in the bucket tek can going to fuck shit up, and I will say, I have had certain bricks consistently fuck me up, especially the bigger ones.

Re: Verm and pans.

I don't use it in casing or substrate.  If I wanted a deeper more compact sub, I would use something with less moisture retention for aeration, such as small perlite.

It's like never used in gourmets, and there's been more money and research done on agaricus mushrooms than any other poo lover.  I've seen studies where it was used in casings and it did poorly compared to controls.  Same with my own experiments, verm has always done poor compared to just peat.

Also, pans do not colonize coir or verm well without the presence of nutrients from the rest of the substrate.  Which makes any water locked up in that material difficult for the colony to use.

When I was researching casing teks 3 years ago as I was really getting into pans, the idea was cubes fruit at 70f, agaricus bisporus 60f.  So the verms job was to protect against evaporation at higher temperature.  To keep the casing damp.

But the issue with that in my opinion is that it's not necessarily accessible to the mushrooms.  See my poor colonization comment above.  And generally most of the water that goes into the mushrooms comes from the top of the substrate and the casing.

In other words, a casing isn't supposed to just stay damp the whole time. The colonies should be constantly pulling water out of it, and the cultivator should be constantly replenishing that water supply.

I plan to experiment again with coir, because it has a better water holding capacity than verm and releases water more easily.  I'll still be using peat too, but recently I read a study where 30% spent coir (so after it was used to grow tomatoes) was added to peat.  And the results were slightly better the controls, plus it means I can recycle my weed soil into mushroom casing and subs, then into the garden.

Re: gypsum

Gypsum does actually buffer pH, especially if mixed with calcium carbonate  But this isn't so important if we aren't pushing tubs out past three flushes.

I did do an experiment where I added both gypsum and calcium carbonate to grain jars for sclerotia at 1% dry weight each, and the results were pretty impressive to be honest. But I don't need a lot of stones so.

And experiments on standard grain jars I honestly didn't like the extra material in my jars, made it harder to read.

As far as substrate and casing, if I add gypsum to my substrate it's mostly for texture and aeration. Because I have the pellets.  Calcium carbonate I of course do add to my casing for pH. And my plan with casing going forward because I don't like the texture of pelleted gypsum, is biochar.  As that will supply sulfur, while also changing the nutrients in my worm castings into more of a slow release while improving texture and aeration (and if you missed it, I've been experimenting with castings in casing after saying so many great results with cactus soil, which does have some nitrogen...  and often good drainage from sand or perlite rather than verm).

Re: cross contamination.

I can't speak to the trowel because I use a dough knife and mostly work with much smaller trays.

But soap and water is really all you need.  Because yes, grain spawn is the culprit.  Assuming you're doing the bare minimum of dishes.

If you are not doing your dishes, spores aren't the issue. It's nitrogen and carbon that's still stuck to the tray.  Food in other words.

But I do wash my hands between trays, so I don't get one live colony mixed in with another. Or accidentally inoculate my casing or substrate bucket with live mycelium.

1: I've never used verm for cubes, but I feel verm in a substrate is a preference thing. I keep it pretty small scale, that means that if I overshoot my coir hydration I just squeeze out the excess water, but I think for someone doing a lot of tubs the easy thing to do is just add verm to get it to field capacity.

Coir hold less water, but it holds more oxygen, so adding verm will give the sub more water, but less oxygen. If coir holds more oxygen, will it colonize faster even with less FAE? Would added verm let us increase FAE without losing to much water, and thus colonize faster?

2: Compacting the sub has two benefits in my opinion, less side and bottom pins and slower evaporation of the sub. If we put the first question in the equation, would compacting a sub with a lot of added verm slow colonization speed because verm has less oxygen? And thus, as you mentioned, let bacteria and mold(if there is any sus grains) move more freely?

3: I have used verm in my pan substrate by default because the teks said so, but then I read that people were adding it to make the substrate more airy, which didn't sit right with me, as mentioned above, about it not holding a lot of oxygen, the only reason I can think of that would help the mycelium move better is that verm doesn't need to be digested.

I already use straw and that helps with keeping the substrate airy, but because I already liked the substrate recipe I tried changing out the verm with rice hulls, now that seemed to really speed up colonization time for exotics. So now I no longer use verm for pan substrate, but I have increased the amount in my casing, so I still need verm :lol:

4: As long as we are talking about coir with or without verm, it shouldn't even matter if there is a biofilm build up in micro scratches, which is a real thing, and some biofilm can withstand one hour of boiling water and certainly soap and even bleach. But both bacteria and other spores will need a food source to expand and that will only be possible if your spawn was already weakened.

That said, I have washed everything in just dish soap, that be contaminated tubs or infected fermenters. Haven't seen that being the reason anything went wrong other times. I have seen mold grow on the inside of one of my fans that are pushing air inside my dreamer tubs, trays didn't get contaminated.

I've seen PhenoDreamers have a real nasty tray sitting closest to the fan, blowing downstream at two others trays, I believe he left it like that for a month, two other trays were fine.

If I should end up with a tub or tray that always get contaminated no matter how clean my spawn looks, I would just try running it in the dishwasher on the hot cycle, if it would come back even then, well fuck that tub, it's $7, I'll re purpose it to my kids toys and get myself a new one :rofl:

There is so many mold spores in the air and I bet my beard has a lot of bacteria falling in my tubs while I'm spawning to bulk that even if the dish soap didn't get everything in my tub, it's a grain of sand on the beach that is open air.

One last thing to your questions, this is combining your trowel handle that grew mold and cleanliness. As someone already know I do most of my novelty grows in cookie jars. I have this one cookie jar that had a wooden lid. I thought it would be fine, but heeeeell no, that shit grew a mold ball the size of my fist on the the side facing my coir substrate, before I noticed it, guess what? The cubes did their thing and the substrate never contaminated :rockon:

Would just like a show of hands on a few things that I want confirmed are still best practices. My info might be a year or two out of date. Note that these are in relation to cubensis.


1- Pure Coir vs CV or CVG



2- Ultra compacting substrate and then ultra compacted pseudocasing

For a while, people were talking of the benefits of really compacting the sub with a trowel, and then doing the same with a pseudocasing of pure coir. Is this still considered good practice?


4- Tub Cleaning and jagged holes

Most people say that dish soap is enough, but I wonder if that's truly the case, especially if a tub molded out towards the end.



1)Pure coir works fine, verm isn't needed, there's no benefit to gypsum.

2) Definitely helps with side pins, all my tubs with psudocasings work great, onece you spawn contamination time is over.  You either contaminated your spawn while doing clean work or it's fine.

3) Yes dish soap and hot water work fine.  Contamination happens before you spawn.
