I hadn't considered using WC at all until this post by faht. The CV+ just sounded so nice after having just prepped a bunch of poo. I don't mind messing with it, it's just so many extra steps, specifically with Black Kow.

I'm probably going to try using this fertiliser that's available in my country: NPK 2.7:0.4:0.7

It doesn't quite match the 2-2-2 ratio of True Organic but figure it's probably not a problem.

There's some discussion here of bucket tek vs true pasteurisation vs sterilisation with added nitrogen.

I am prepared to do a proper three hour pasteurisation of the substrate with ferts and worm castings. I'll adjust my fertiliser addition to match Fahtster's coir/verm/wc's/ferts recipe.

But my question is should I actually be sterilising my substrate with these amendments? Or will a proper pasteurisation be ok?

you can get a rough guess with volumes of additives on if it's pasteurize vs sterilize. Just thinking about it though, anything beyond lab grade setting, sterilization for bulk substrate is likely a very bad idea.

One you're cooking your media at that point, and two, you're nuking all bacteria and anything else.

That means a clean plate with all those nice additives on top for bad actors to make use of. In my head I imagine trying to do an agar transfer in the open air and then leaving the lid off.


Probably an extreme metaphor, it might not be THAT bad, but personally I would assume pasteurization for our purposes is going to be superior. And if you're pushing your nutrient load so high that you need it sterilized, then likely it was too much for mushrooms to ever utilize before being overrun anyways, be it before fruiting or trying for subsequent flushes.

I need a quick sanity check from someone who's attempted CV+ before....

Have you figured any way of scaling this back as to not have to use an entire batch of coir? I'd love to give it a try but I rarely need an entire brick of coir and normally just leave my leftover coir in the bucket which does seem to last quite a while (months) and still being usable later on

earlier in this thread, user and public hero "nocap" helps me with that very problem.

Prep your coir without verm.  When you go to use the coir, add the nutrients to the water you hydrate your verm with and mix it well with the coir.

I suggest pasteurizing prior to using it though.

And yeah what other folks said about scaling ratios.

I must ask...does anyone forgo verm? I'm using coco bliss coir.
It's been awhile since i bought my verm (like years) and I know it was $$ back then.

Looks  like it's more available now...$8 at Target for a fairly fine grade. Thoughts?

Also, I misread the whole dosage thing, so my grow has 20/20mL mixed into 4 quarts coir (and pasteurized). Soo about 2.5-3x stronger lol. Let's see how it goes~~

I don't use verm.  But I do use worm castings and biochar for texture.

Actually added some nutes to my last batch of AIO.  And since the substrate was prepped I just mixed it in with a little bit of water and then poured that over the grass seed to distribute.

I saw faht and you talking about C+ WC...do you feel the worm castings provide a significant benefit over simply C+ (or CV+), especially if, as faht does, decrease the amount of supplements to account for the addition of the WC?

I don’t actually decrease the plant ferts.  I just scale it down per tray but the ratio is the same.  40g of coir is roughly a 1/16th of the 650g block.  So dividing the 20ml by 16 gives me the ~1.25 ml per tray

I'm cribbing from fahtster, and haven't ran the WC+ yet (though I have some prepped waiting for space and cultures).

So everything I will be posting for the next month or so is the prep from my AIO thread (popcorn, grass seed, coir, castings, and biochar).

Anyway, for the fresh batch I added a ml of each to one quart of prepped substrate (so that includes everything minus the popcorn and grass seed).

Ahhh ok, got it for both of you. Yes...splitting down to dosing per quart or tub works better for me than dosing the whole thing. And noted from both of you on the WC with fert.



I won't flood this thread with constant updates...I'll keep updating this one post. Towards the end I'll trim out pictures if they seem irrelevant.

Disclaimer: each tub is a separate 'pull' from the mother plate, ie different genetics.

For the following "C+" means 20mL True Organic + 20mL Jackpot per 8 quart coir.


Anyways Cubes:
1:4 sub
Day 5 -> Day 11 -> Day 13 -> Day 17 -> Day 19

MAC - Plain coir

(Pins on day 10)


MAC - C+

Pins on day 11

^^this one's interesting as it's the only one where pseudocasing myc looked different. Both had rhizomorphic appearance on the side and bottom substrate, but on the pseudocasing the plain coir had clusters of 'single' threads poking up everywhere, whereas the C+ had more condensed / thick / unified eruptions. They looked the same on agar. Also, at least at pinning on C+, it looks like it might be developing some blobs.


Machine Elf:
1:4 sub
Day 4 -> Day 6 -> Day 10 -> Day 16

Machine Elf - Plain coir


Machine Elf - C+

Not doing anything for multiple days, surface still has micro-dew.


And Pan Cyan:
Day 4 -> Day 8 -> Day 10 (cased) -> Day 16 -> Day 18

TTBVI - Manure
1 : 1 : 0.75 : 3
Spawn:Manure:Verm:Coir


First pin Day 15
Side view Day 10 after casing


TTBVI - C+
(just 1:4 supplemented)

First pin Day 13
Side view Day 10 after casingTTBVI - C+ : Cluster Day 16


assuming I simply waited a bit long to case both. They smelled fine so I'm guessing they were just sweating orange as they were done with colonizing.

==================================================

==================================================

I didn't bother taking any other interesting pictures as it was pretty much all the same from there. I'll summarize dry data and flushes here:

MAC C+ : ~71g
MAC normal: ~35g
Both about 3 flushes

TTBVI manure: ~5g
TTBVI CV+: 7.25g (maybe closer to 7.6g as there's a few stragglers)

Machine Elf: Both boxes didn't produce, one clearly yellowed , the other produced a large brain blob. Weird as they were different cultures, but maybe the mother plate had bacteria riding along.


The TTBVI bins were inside my tent which was undergoing tuning so the surface definitely suffered several times pretty significantly.

I recently ran a tub of Zapotecorum Tapalpa on some old leftover CV+ that had sat for about two weeks. I usually toss my leftovers or roll them into the next batch, but I had extra room so why not. It did surprisingly well. I ran another culture alongside it on a fresh batch of CV+. The mycelium looked visibly weaker on the old substrate, but ultimately colonized and fruited fine. It did however mold out after the first flush, approximately 2 months from spawn. Not sure how a more delicate species will tolerate it, but I have many pans in the pipeline so I'll check that out shortly.

I just saw the note about organic vs synthetic after I received this, but before I started hydrating coir:



I'm thinking these TTBVI jars look pretty clean




Any thoughts? It's not a big deal to pasteurize some manure instead.

Edit: found the answer a couple pages back. Gonna go with the fert, but I'm gonna pasteurize it

Currently, as an experiment, I'm taking my chances with water soliuble NPK with regular bucket TEK. Will report back.
I also wonder it it is posiblle to do something like a liquid manure pasturization but with ferts - so basicly heat the water to some calculated temperature that will result in proper pasteurization temp after adding fert and coir.
