How rough are you when mixing spawn to substrate?

I'm just curious about what YOU do. This topic is mostly for the "bored out of your mind" crowd.
Mixing your spawn in to your substrate is a widely accepted practice. That's how I do it.
However, in RR's "Let's Grow Mushrooms" the chapter "On Horse Manure", he says he layers because mixing can damage the grain and expose the un-colonized inside which can lead to contamination.
I think some peoples substrate contamination issues may be from mixing to roughly, as opposed to it always being a "ninja in the spawn", like so many are quick to say.
I don't doubt the hidden contam argument, but I also think people may be too quick to jump on that bandwagon without considering the rough mixing possibility.
I usually read something like "If you use CVG and get a contamination before the first flush, then it's your spawn." Is it possible that statement could sometimes be a little short-sighted?
If you're a mixer, I'd like to hear from you. Maybe you have some sort of analogy to describe your mixing? Do I make sense at all?
I'm not trying to start a "layer vs mix" debate. I just want to examine the mixing in a little more detail in the form of friendly discussion.

I pour all my sub in the tub and then I pour all my spawn in. Wearing rubber gloves I just reach in and start mixing until I feel it's mixed evenly. I wouldn't say I'm rough with it but I'm not gentle either. I've never had trouble with contams. Also I usually use the bucket tek. I use coir / verm / gypsum

I saw that when I first started out but mixing seemed to be more intuitive than layering. I mixed from the get but gently, I'll go into that below.

I could agree with that, not that I have the necessarily experience but it makes more sense.

I don't use gloves just washed hands with regular soap not antibacterial because why bother. I make it pre-mixed by layering the sub and spawn into a gigantic plastic mixing bowl. Then I just lightly(as to not break grains light) mix the spawn. I would say the analogy would be like mixing sand with a few pieces of broken glass in that you can't see. You want to mix it light enough that if you by chance got a piece of glass near your hand you wouldn't cut it because of how gentile you're being.
As for ninja contamination I don't think it's as rampant as it's cited. I remember Frank saying he had a petri that looked good but under a microscope he saw contams running along side healthy MYC. That's probably a rare case but I couldn't say for certain. (I have read way to many threads here )

I just make sure all the grain is separated and spawn to cvg. Never gloves, Lysol, or anything. With horse dung I do the same, although I haven't used it in a while.
Clean spawn a and pastuerized substrate and you should have no issues with spawning

On this I would just like to say that when I was doing cakes I did several jars of both types and I had success with both. Although I noticed much faster colonization times with the short wide mouth jars and they fruited just as good if not better than the tall ones.

And on that note I have never used the wide mouth 1/2 pints to compare. But with that said my colonization times are always in line with the average times cited for "proper" pf jars. If they're obtainable without having to spend twice as much for online shipping I would say use them if not the tall guys wont hurt your chances.

The thing I have learned about the tall jars is that you have to load the substrate very loose in them to keep them from wanting to stall on the bottom

I made a funnel that has it's "aperture" as big as the top of the jar I put the BRF mix in my hands and crumble it into the jars so that it's as light as possible. When I put the verm barrier on I didn't tamp it at all but it was just tight enough that it would be prohibited from moving around by the slight tamping of the screwed down lid.

Anyone done a side-by-side with layering vs. mixing with an isolate? I always layered after I read someone post that their subs wouldn't crack or break as often when trying to dunk it but that was a few years ago.

Most of us don't dunk our bulk subs anymore. We just mist heavily as needed after the first flush

Well, I've never done a test. But I would advise against laying for 1 reason. When you layers, your myc grows in 3 planes. Forward/backwards up/down side;side. When layering, your spawn grows over brother grain from side to side. Wouldn't you want your spawn mixed evenly so on all 3 planes it grows into sub rather than other grain, which is already colonized?
And don't use a frosting laying. Grain dries out on top and that's a great place for trich to grow

The biggest problem with mixing is if grains are left exposed on the surface. They dry out, and then when you mist they end up with green molds. If you add a casing layer, or even a thin layer of bulk substrate material on top after mixing, it takes care of that issue.
When I use filter patch bags for my sawdust or other bulk substrate, I always shake to mix well. With bulk substrates in trays, I've noticed slightly better performance by layering, but either way is fine. Just don't forget to put some substrate on top to cover any grains so they're not exposed. RR

I dump everything in the tub and mix it gently. I dont throw it around and mix as hard as i can. I gently swirl around the grains and bulk until evenly mixed, slightly pat sides down and vwala done. Take your time mixing slowly scooping the mix rather then digging around so you dont crush grains against the sides and bottom of the tub.

Stromrider, bodhisatta, and Jw6457, thanks for your descriptions.
The rest of you have missed the point.

Just don't forget to put some substrate on top to cover any grains so they're not exposed. RR
I've always been curious, isn't this the same as leaving grains exposed?
If you cover with say a thin layer of pasteurized uncolonized coir, isn't
that just going to be a buffet for contams and dry out faster than grains
during colonization?

Covering exposed grains is not really necessary, I have never had a problem with not doing it.
The substrate seems to colonize faster, for me anyways....and a few TCs as well.
It's personal preference really....my tubs colonize in 6-8 days without a top layer usually.
However if the top layer is thin enough, this should not make much difference.
I only said what I said because it is hard to judge the amount you apply, so for some people they can make it really thick and not really notice until it takes forever for the top to finish....then they realize.
We keep the substrate somewhat sealed, and the grains are already fully colonized, so I highly doubt the substrate will dry up in a week....even the top layer.
If it takes longer than that then I could see there being an issue.

For spawning, I:
Dump half the substrate in, spread it out.
Dump the whole bucket of dunked spawn in, spread it out.
Dump the remaining substrate in, spread it out.
Mix it quickly and very thoroughly. I never even take into consideration how gentle or rough I am with it.
Even it back out.
On the issue of handling the grains, I have actually done a few things I thought for sure would lead to problem.
I had very thick mycelial growth on WBS bags before and I broke the grains up mostly by hand. I broke up what I could before opening the spawn bag and dumping it into the cold dunk water. Then I broke the rest up by squeezing and squishing the chunks of mycelium apart. I was very rough with them by anyone's standards.
I haven't seen any contam issues because of it, the grains always seem to recover fine as well.
Not saying that this is good practice, just that when circumstances arose and it needed to be done, it hasn't caused me an issue yet.
