First monotub, colonization time?
    #22156551 - 08/28/15 01:00 PM (8 years, 5 months ago)

Hi guys and gals.

I got my first monotub going, following this tek.

https://www.shroomology.org/topic/46-how-to-grow-shrooms-in-bulk-monotubs/

I used around 2L of rye berries nocced with spore syringe, spawned to about 8-10L hpoo/coir/verm substrate. Checked once after 7 days, it was looking healthy, lots of surface coverage of myc, maybe 50% from just peaking at the surface, and it looks really wet.

I thought it would be done after another 5 days. I checked again today, total time 12 days, and the surface still isn't completely covered in myc, i'd say it's about 80%. And there are a few really wet spots which appear to be standing water.

Is it too early to worry? Should I give it another 3-5 days and check again?

Or maybe it's getting contam and/or stalling? In that case should I just put into fruiting condition and hope for the best?

Temps were on the lower side last week, i think the ambient is about 22-26, maybe that's reason for slow colonization?

Thanks for any advice!

compare it with this tek 12 steps to monotubs and see if yours was off.

and post a pic.

The guy who wrote that tek is a dumbass......my god.....

Dumbass from Shroomology said:
5 gallon bucket
large tote (for mixing sub in not the monotub)
1/2 brick of Coco Coir
Pot to boil water in
6 qts COARSE grade vermiculite
4 qts cmc/HPOO (Cow manure compost/ Horse Poo)
Hydrated/Pickling lime
8 cups of water.
Large oven bag
16qt(or larger) Pressure cooker
Coco Coir can be found in Petsmart or any pet store that sells reptiles. It is used for reptile/arachnid bedding.

Bring 8 cups of water to a boil.
Cut brick of coir in half
Put coir in a 5 gallon bucket
Pour boiling water over coir
cover with the bucket lid or a towel for 15 min
stir coir up so that it is all broken up, evenly distributed, and fluffy
Allow coir to sit for 1 hour, covered, to hydrate fully.

While the coir is cooling, move to the next part of sub prep

Pour 4qts of cmc/Hpoo into a large tote for mixing.
Add 2 TSP of lime (to buffer PH of poo and coir. it is required for multiple flushes).
Mix as well as humanly possible.
Add 6 Qts of COARSE grade verm. (YES it must be coarse grade)





First of all, coarse grade verm is the worst option....fine verm is a lot better, as it holds more moisture and has more nutrients and more surface area.....

To get field capacity for 1 brick(650g) of coir + 3qts of verm you would need roughly 160 ounces of water.

He is using a half of a brick of coir, 4qts of manure, and 6qts of verm, but only using 64 ounces of water.....:rolleyes:

Lime is not needed at all.....it IS NOT required for multiple flushes.....that is the stupidest thing I have ever heard.....

&& Lime is for casings not bulk; lime usually has Mg, which is generally bad for mycelium

If they are colonizing best thing to do is leave them alone. Cover your tubs with a blanket and let them sit at least two weeks or more If they are good sized tubs that is. You want high co2 levels when colonizing.

A blanket? Two weeks? You mean foil or maybe a lid? If I had a tub colonize in two weeks I'd say it has a problem.

haha, oh man, well I really didn't spend enough time to do research then, I just found what seemed like an easy to follow tek that seemed to work for someone else.

I'll take some pics in a few days, I'd like to avoid opening it too often.
It's got foil and a lid right now.

Thanks for all the comments. :laugh:

Edit:

I read Frank's 12 step guide and tried to compare the differences.

I can get rye grain spawns fully colonized pretty reliably now so that step is fine.

I didn't know about dunking the grains before spawning to bulk when I did my 2 first tubs, so that'll be for the next experiment.

It seems the spawn to sub ratio is roughly 1:1? He made 12qts of spawn, 1 brick of coco + 2 qts of verm, and I believe 1 brick coco comes out to around 8 qts.
So in that case my spawn to sub ratio is way way off, that could account for the slower colonization time.

There's no mention of using poo in Frank's tek, I'm assuming all the nutrition of the sub comes from the coir? Because verm is mostly a mineral right?
Is there a big difference between a tek that uses poo + coco/verm and one without poo?

He also doesn't do a 140-160f boiling pasteurization stage for the sub, I watched the "Let's Grow" videos a few times and the part about preparing bulk sub contains the pasteurization, so I did mine the same way for one tub, the other I sterilized the sub in a PC, because I don't know better, and also just to experiment and see what happens.

It seems it's enough to just pour boiling water into the sub?

What I'm wondering is, if I did something so different from what you guys consider to be ideal, and it's still colonizing steadily, that means cubes are just really really tolerant to variables in growth conditions, right? Or maybe I got lucky somehow, somewhere.

In any case, I would like to follow Frank's tek closely for the next run and see what happens regardless of what happens with this tub. Always fun for me to learn something, even through spectacular failures.

I appreciate all the help and pointers I can get along the way though, so keep 'em coming! :smile:

You don't really need high Co2 neither

You need high CO2 to colonize properly, or rather low O2. Fresh air stimulates pinning. You don't want that during colonizing.

Low o2 yes but ime no need for high Co2

Well the myc gives off the CO2 so high CO2 may not be needed but it's a result regardless :shrug:

What makes you say high CO2 is not needed?

You don't want it, but it's not gonna pin until it's fully colonized regardless...

My first tub I didn't mix my spawn, I layered it all on one layer and I left it like that until I saw a bunch of tiny white dots and then I posted the picture and was told it was trich.

Then I woke up the next morning and saw a pin. Sub wasn't even near fully colonized top or bottom. I think this was just myc expanding to it's maximum and then given proper environment:



No contam, flushed two more times until it couldn't.

When i stopped taping holes and stuffing the holes the same as a fruiting tubs but top holes just a tad bit mo tight to keep the evap line from getting to crazy to prevent drying. Your perdy ass tub speaks for itself as well my friend

I let the first tub go for another week, it was total 3 weeks when I checked again.
I also checked the second tub which I started 1 week after the first at the same time, so total incub for that is 2 weeks.

The first one stank in one area when I opened up the tin foil, it was the area which I'd previously observed a lot of standing water. It developed some contam, there was a small patch of cobweb, and some yellow liquid stuff where the smell came from.

I noticed that there are spots of standing water with yellow coloration spread out on the surface of the substrate, which is now almost fully colonized, except for the area surrounding the contam.

I noticed there were water still trapped between where the pieces of foil overlapped, I did that becaus I didn't have foil wide enough to cover the whole thing with, so I used multiple overlapping pieces.

I'm guessing the contam comes from the water, so I took a knife and cut out the area with the contam down to about 1" deep into the sub, and threw it away. After that the tub smelled only of fresh mushrooms. So I put it into fruiting condition, and now I'm waiting to see what happens.


The second smaller tub also had the same thing, several spots of water, on this one there is no bad smell yet, and not all the water spots were yellow, some were still very clear, some had a yellow tint, but weren't a intense yellow looking goo like in the first tub. I guess it was heading in the same direction as the first tub, so I took a piece of fresh paper towel, dabbed away the standing water bits, using a fresh piece of paper for each dab, and then put it into fruiting condition.

I'm guessing maybe it was a bad idea to put the foil on?

Any thoughts?

ok, so it's been 5 days since I performed the "surgery" last time.
I placed only very loose pillow stuffing in the holes and put a small fan running near it, not directly as the tub.

Here's the big tub, 57L. The area i cut out with the severe contamination has since been fully colonized again with myc. There is still some yellow colorations around the tub, but they don't seem to be changing, and there's no smell.





This is the area I performed "surgery" on.


Here's a close up of the water droplets collecting all over the surface.
The yellow stuff looks unhealthy to me, but they're not developing or producing a smell.
Is this because the myc has a strong enough hold that it's stopping contam from spreading?


This spot hasn't changed much for the last 2 weeks, I wonder what's stopping myc from colonizing here?



Here is the small tub, 27L.

As you can see lots of water collecting on the surface.
Is this bad?






The whole surface has gotten more fluffy and more "bumpy" since I placed the loose pillow stuffing and a fan nearby, same as the big tub.

FYI total colonization time 3 weeks for the big tub, 2 weeks for small tub. Then 5 days of what I think is "fruiting condition", ie a few spray + fan in the first day, then loose pillow stuffing and fan in vicinity.

Any advice?

Cheers!
