How Spitball Prepares CVG 16

This tek is pretty much overkill if you are using CVG. However, it can also be used for bulk pasteurization.
This is part of my series "The Basics"
Now that my grain spawn is ready, I'm going to mix it with a bulk substrate. In this tek, I'll be preparing bulk substrate made of coco coir, vermiculite, gypsum, and water (CVG). I will be using a monotub for colonizing and fruiting.
Let's get this out of the way first. CVG does not require proper pasteurization or sterilization. Questions and comments on the subject can be found on Bucket Tek vs Pasteurization Thread . That is the end of the discussion on this thread, period.
The CVG recipe is: 1 Brick (650grams) coco coir 2 quarts fine-medium vermiculite 1 cup(2 big handfuls) garden or horticulture gypsum 4-4.5 quarts water
The average brick of coir weighs about 650g, but I've seen them anywhere from 550-750. If you are using one of those big bales, knowing this may be useful. Although this is not an exact science, a wide variation on the amount of coir you use may result in too wet or too dry substrate.
Following my measurements exactly will give you an understanding of field capacity. This is because CVG has been used so much and the weights and measures are so uniform.
If you use the above recipe, 4qts of water would be considered on the dry side of field capacity and 5 quarts would be on the wet side of field capacity. But, they are both in the range of what most people consider "field capacity".
There are many ways to prepare CVG and this is just another one.
Here we go:
I will keeping the CVG hot with a water bath. Basically, I'm using one pot to prep the CVG, and the other pot will have hot water in it to keep the CVG hot.

This is the two pots, one inside the other. I have two identical 21qt canning pots. One for the CVG and one for the bath.

Use one pot to boil 4 quarts of water. Use the other pot to heat water for a water bath. You'll have to figure out how much water the bath will need ahead of time. It will vary depending on pot size.
Boiling 4 qts water
Once the 4qts of water gets boiling, turn off the stove and put in the coir and vermiculite and put on lid. At this point, you can go ahead and stick the CVG pot in the water bath which should be hot by now.

After about 10 mins, it has soaked up a lot of water. Sprinkle the gypsum in on top.

Mix it up. It will still be very hot. I use a wooden spoon to mix. It doesn't have to be mixed all that well at this point because we can mix it again when it's cooled.

Put the lid back on and set a timer for at least 1 hour. This part is not critical and I only do it because of the water bath. The timer reminds me to turn of the stove being used by the water bath. It also insures that my CVG has stayed at a high temperature for at least an hour. The timer has nothing to do with making sure I'm killing bacteria.
This bath easily keeps the CVG at or above 200F.

Once the timer sounds, turn off the water bath. To cool the CVG faster, remove it from the bath as well. Once cool enough to touch, you can go ahead and mix real well by hand. I like to wear a glove because I don't like digging CVG out from under my nails.

Alternately, you can also just dump the hot CVG in to your monotub if you want. It will cool faster because it's more spread out.
Further discussion
The point of the extra step of the water bath has nothing to do with pasteurizing, sterilizing, killing bacteria or any of that. The point is cooking it to break it down so mycelium will colonize it faster.
There is growing evidence that cooked coir is great for mycelium and may be the only reason for heating the water at all; it seems heat breaks it down so it's easy to digest. People are having great success even with sterilizing CVG. CVG is the only substrate I'm aware of that can be sterilized and then spawned in open air.
To be honest, you may find easier ways to prepare CVG than this tek. Mainly, you'll find many teks and posts of people just throwing all the dry ingredients in a bucket and pouring boiling water over it. This works fine and is basically what I'm doing here. I'm just adding an extra step to keep the substrate hotter longer so it cooks a little more. The water bath is not a requirement, but it's what I do. Feel free to omit the water bath.
I also prefer the pots over the bucket because the pots are wider and not as deep. It makes mixing easier for me.
Now it's time for Spawning.

Huh? But pasteurized subs like poo are still okay to spawn to in open air right? I know it's different than sterilizing inert substrates like coir and verm, but your wording had me worried for a moment.

Yes, properly pasteurized manure can be spawned in open air, sterilized manure can't, as far as I know.

This is kind of a general question, but is there a reason why you add only 4 quarts, when you also mention that 5 is also acceptable? Since drying out seems to be a big issue, why not go with 5 quarts? Why risk drying?

You can use anywhere from 4-5 qts of water with this recipe and it's still considered field capacity; it's a matter of preference. I mentioned the range for people who still don't quit understand what field capacity is.
I dunk my grains, so if I used 5 qts of water in my substrate it would be too wet and either stall or grow tiny fruits.
for this tek, I used 4 qts water because it's better to err on the dry side of field capacity when just learning to do bulk. If it seems too dry, then just add more water next time.
Your sub shouldn't be drying out with this recipe; it's used by a lot of people. If your sub is drying out, then you may want to try turning off the fan in the room, if you're using one or adjusting your polyfil. I usually don't use a fan.

Thanks, I shook up my jars four days ago, and they've recovered a lot now. Others told me to wait until the jar is completely white, with no visible grains, so I'll wait for that... might be another couple days 'cause some outlier grains seem hard to reach.

i did this recipe but prepped it slightly different to factor into the methods i use.
i just boiled water. dumped all the ingredients in a big mixing box(plastic box).
put the lid on for about 20 minutes.
once expanded threw in all the other ingredients like the gypsum and i added some extras like a little coffee and supercake formula.
mixed it all up and then pasteurized it.
so far so good. i have great growth after 2 days!

yes you can open air spawn all kinds of substrates. every substrate ive spawned was open air.
over the years ive tried:
cow dung/straw coir/verm/strawnet cat country straw pellets black cow(dirt lol)/straw horse dung/straw/verm coffee/coir/verm various mixed composts from vendors donkey dung/coir/verm

Ok i got that first part now now butif you put boiling water into a substrate that needs to be pasteurized aren't you defeating the purpose of pasteurizing(partiual sterilization)? EDIT: OK i Get it the boiling water is added to the Coir verm first and after it cools some (20 Min) the other ingredients that need pasteurization are added .... GOTCHA sorry for the confusion

Yes. I would wait for it to coll before adding other ingredients like manure, coffee, or castings. I would imagine it takes longer than 20 mins though or you might partially sterilize the other substrate materials.

yeah im doing a 2 hour pasteurization when i add these ingredients. but i can see the beauty in doing this in an hour!
Its real quick and easy!

the boiled water just breaks up the coir brick so that i can mix in the rest of the substrate. sorry follow spj's directions for plain CVG. im adding some things so i used a little different methods. i was trying to explain it earlier. hope this explains it.
and you can wait until the entire batch cools before pasteurizing it. you can wait longer than 20 minutes if you want.

I'm seriously glad you wrote this. Vindication!!
This is relevant, and not an attempt to rehash this argument here. Anyone who wants to argue with me can do so elsewhere. With that said: I have had the *exact* same experience with bucket tek and get the same arguments. I've had the same clean agar, same clean grain spawn (seemingly, anyway), same everything until it comes down to spawning, then BOOM! Trich. Glad to see that proper pasteurization has worked for you, because it's the only thing I haven't tried to make this go away.
With that said, I have also had issues with coir not reaching full colonization, and there's some RR quote floating around essentially stating that it's not uncommon for uncooked coir to not reach full colonization because "raw" coir is hard for the mycelium to digest. Therefore cooking your coir helps break it down so you can achieve full colonization. Which, I guess is the point of this write up. I understand that my problems with the substrate not achieving full colonization could be due to the trich infection, but I would imagine that cooking the sub like this would replace the need for further treatment for contam-prevention. Has this totally obliterated any contam issues you've personally had in the past as a side effect? I seriously hope this would kill two birds with one stone.

Maybe I'm confused here. but In this tek, it seems like you are trying to say that you are not pasteurizing... even though you are totally pasteurizing. It doesn't matter what your intentions of the hot water bath are... you're still pasteurizing it.

This is not proper pasteurization. My temperature stays way above proper pasteurization temps.
The hour I leave it on the stove is the common pasteurization time, but don't be confused by this. I set my timer for an hour so that I don't forget to turn off the stove, but yet give the sub a solid cook time. I'm easily distracted and sometimes forgetful. You can set your timer for longer if you want.
Often, I just turn off the stove and go to bed or leave the house once the timer goes off. This means the CVG would be sitting too hot and too long for proper pasteurization.

200F is to hot.. that sterilizes your sub.. you want pasteurized sub.. best way i've found is to heat my water to 175 degrees and pour it on off the burner in a cooler and close it up.. the cooler will keep it a perfect 145-170 for hours.
bucket tek failed for me several times as well, i switched to doing Franks jar tek but that was very tedious.. the act of taking the water to 175 + a cooler to keep the heat in has really helped my pasteurization process.

No. 200 is not too hot for CVG. It's too hot for proper pasteurization, but not too hot for prepping CVG. Your method works, too.
CVG does not require proper pasteurization. If you want to debate it, go here: Bucket Tek vs Pasteurization Thread

You can sterilize your CVG and still will be contam resistant. CVG is a special case, not the same if you use manure.

Hi Spitball I have bin looking around to find a bulk substrate that consist of ingredients that are obtainable where I live. I have not yet found such, so I think that I need to rethink things and start asking around for a little help; I have asket around to be hook up with some coco coir, but Nobody from around seems to know about it, I can hoverer get something Terrarien Humus: http://www.amazon.de/Terrarien-Kokosfaser-Ziegel-Brikett-Kokoseinstreu/dp/B006G9E0T6 I think it looks a lot like the coco coir, Can I use it instead? Am I so lucky that it might be what people from your part of the world would know as coco coir?

Couldn't find a brick. Found a box of what they call 50 plantable coconut coir pellets. Each weighs around 7grams. I unwrapped enough of them to weigh what a brick does. will these work?

yup, they work fine but need a tad bit more water for some reason.

you let them recover to see if it recovers right away or if any issues occur as a last chance contam check.. I just breakem up and spawn them. you want a ratio of 1 part spawn to 4 parts substrate minimum. I prefer 1:2 myself. more spawn= more inoculation points= faster colonization times= more energy left for fruiting and multiple flushes.

Could i still pasteurize the substrate after using this method, or will it over cook the coir?

You cant over cook the coir. There would be absolutely no point to pasteurization after you already partially sterilized

Is there any tek that you would recommend? Do i just simply mix the Coir, verm and gypsum with boiling water and then allow to cool?
From what i've read i thought that the bucket tek was a more risky way of doing it.

Is there any negatives to sterilizing or do you think its best to be on the safe side and sterilize it?

i only sterilize to store it. sometimes i find myself only needing to spawn a small amount. so i sterilize the rest in bags so i can use it on the fly either way. coco coir is awesome. i wish i grew coconuts.

Oh ok good to know, i guess im gonna try the bucket tek then. Definitely seems like the easiest way.
Are coir and vermiculite both pretty contam resistant? Because ive heard many people mention that coir doesnt require pasterizing but nothing about vermiculite.

coir is like a reptiles cat litter. verm is a rock. mold will grow on coco but it doesnt seem to germinate. hence the importance of clean spawn.

Update to OP.

This tek is pretty much overkill if you are using CVG. However, it can also be used for bulk pasteurization.

Is it possible to prepare this in advance? After some research i realized my rye grain jars arent quite fully colonized (soo close). For example, could I store this away for a week and use it then? I prepared it exactly to the recipe so it is not sterilized.

Great, thank you. I dont need to be concerned with bacterial growth? Whats the best way to go about checking moisture levels?

This recipe makes around 10 quarts, most bricks of coir are about 650g and expand to approximately 7-9 quarts. So perhaps just use a quarter of the recipe to get around 2 quarts, you could probably use a lot less gypsum too.
"2% to 3% by dry weight or just add a tablespoon or two of gypsum to the amount of coir to fill a small tray." -RR

Your coir should say how much it expands. Then add your verm if you wana use that stuff.

That's a 1:1 ratio with 2 quarts of sub. It's not an exact science but that will work well. I'd personally recommend 1:2 but it's all about finding what works for you. Anything between 1:1 to 1:4 works well, some people stretch their spawn even farther.
Best of luck!

1.2 ratio? Ok i will try that sorry for seeming ignorant but would you mean double the amount of sub to 4 quarts for my 8 cakes?

1:2 = 1 part spawn to 2 parts substrate, so yeah that's correct.

Thanks, one more thing just out of curiosity. When applying the 1:2 ratio would you measure it by volume or weight? For instance once ive cooked and hydrated my cvg to get an exact measurement would i weigh or measure mass?

Would loose coconut fibre substrate also be good for this? If I was to weigh it out to 650 gr?
Is there a difference between the ones that are used for terrariums and for gardening?

the loose coco fibers usually dont hold water as well as the hull/husk powdered bricks do but they still work. you may have to re hydrate more than usual but it'll work.

Quick question about gypsum. Where I live, I cannot find gypsum, at least not horticulture gypsum. The only thing I find is construction gypsum. Is there any difference? Can I use that one instead?

How much substrate does this recipe produce and how much do you think I would need for a 54 quart monotub? Going to do rye grain spawn. How much of that would you recommend? Thank you in advance.

Usually 9-10quarts total or whatever the label says on the packaging.
1 whole brick to 4-6 quarts of spawn in 54qt tub sounds good.

Hi guys,
My thanks to Spitball for this informative procedure.
I'm an old hippy noobie. Please bear with me. I have a Sterilite 1933, 32 quart tub. I'm planning to transfer 10 1/2 pint BRF jars to bulk substrate. That's 2.5 quarts.
Spitball's tek seems to produce about 8 quarts of substrate. For a 1:2 ratio of spawn to substrate. I only need 5 quarts.
Can I simply place the remaining substrate in a zip-lock bag in the refrigerator until I need it again? If so, for how long?
Much thanks,
Tom

yup, you can store coir/verm for a few weeks with no issues.

Gypsum is a waste for cubes. Lentulina edodes perhaps could benefit. Cubes not so much. Maybe if I was doing peat casing for a PE grow I would add a little to help stabilize the pH a bit. Otherwise it’s pointless IMO.
