Correct me if I'm wrong but alcohol isn't sporicidal and that hand sanitizer likely isn't either, so while there may not be bacteria on it you're probably putting tons of contam spores in there that germinate quicker than cubes.
But worth a shot, I tried using iso on a spore print recently, similar reasoning.

Guys, I am using ghetto PC too, here is how I've modded it with a gauge and additional weight to keep 15 PSI:

Hi all
Any idea what is going on here. This is 5 days. Agar grown b+. Transferred - clean - put to rye. Rye soaked for 15 hrs. Then boiled for 10. Then allowed to steam cool a bit and dry off out the outside.
PC for 90mins @ 15 psi
Virtually no movement from the point you see here. The left side of all pics was the past Sunday. The right side is tonight. Like nothing. Only think Iβm wondering is my quart jars have no holes. I thought holes were for when injecting.
Any thoughts?

Are the lids cracked or any other means for GE?

I see folks post about getting 8 dry oz's off of 5 qts of spawn from the first flush which is like 1.6 dry ounces per qt of spawn. I use 3 qts of spawn and yield 3.5 dry ounces. With this tub and many others that I have had wall to wall flushes I am only able to yield about 1.15-1.3 dry ounces per qt of spawn on the first flush.
How much does surface area play a role? I am using 15 qt tubs where as most folks use 54+ qt tubs. Which I am sure the bigger tubs have more surface area. Would I be able to pull the same yield with less spawn on the first flush? Just wondering if surface area is a limiting factor and perhaps I can stretch my grain a little further if I only plan on a 1 flush and done grow cycle?

I'd say the major factor would be the availability of water in larger subs, combined with the surface area to utilize that water for heavier harvests. My smaller tubs never compare to a full sized mono. Like pasty always says, a good culture will move ~70% of the available water into the fruits, so there's a correlation between sub size and harvest weight of fruits.

I understand what you are saying but my subs aren't lacking available water as they are still pretty heavy after harvesting the first flush. I don't think the canopies can get any more dense either on the first flush. As there doesn't seem to be anymore room for them to grow.

Perhaps I will cut back to 2.5 qts per tub and see if I can still produce the same total yield.

No lids not cracked and no holes. I thought holes were if you were injecting a syringe. Is that the issue? Oxygen deprivation? If so Iβll just open then in front of the flow hood to allow for an air exchange and make holes in the tops.
Is that your belief whatβs going on here?

Iambrownbear-There are some 18 or 19qt tubs I used for mini monos a while back. They are actually shorter than the 16qt ones so they give a bit more floorspace. Might be worth checking out? I can't say if surface area really will play a role, but would be great for a side by side test to find out. I found them on sale, like 4 for $10, a while back. Wish I had grabbed more.
Uzimyco- Yeah, they need air. You can crack the lids about a quarter turn. This will allow for gas exchange. Contams will not freely flow through obstructed pathways unassisted so some people just do this instead of poly fill\SFDs\mp tape. That would make me nervous as fuck though so I use SFDs or micropore tape. You can't just poke holes without a way to filter out contams. If you have more lids,you can mod them, then pc them, then switch them out. If you take the current lids off and mod them, you will need to pc them again before putting them back on.

Its not about density at this point. If you have a sub that holds 5 liters of water and a sub that holds 2.5, the sub that has more water will have a higher BE with the exact same density. Not only because of the water though, the increased surface area means there are just more mushrooms.
Your smaller tubs have less water than the people running full sized monos getting the dried weight you described.

I have also had wall to wall flushes with envy ss in the same size tubs. The yield was very similar to these whytegold tubs with very dense canopies like the ones I just posted. The only difference was that the envy ss are a lot meatier and so I had less total mushrooms per tub.

That is what I am saying though. The substrate still has a lot more available water after the first flush which was not utilized. My substrate is still so heavy after the first flush that I don't even have to soak it in order to get a decent second flush. However, with the way I want to cycle tubs, I really don't want to run a second flush. If my 15 qt tubs can only produce x amount of weight on the first flush no matter how much spawn or available water there is in the substrate than I was wondering if it would be ideal to just cut back on spawn used per tub and still get the same total yield per tub?

Same thing happens with PE.
You asked:
How much does surface area play a role? I am using 15 qt tubs where as most folks use 54+ qt tubs. Which I am sure the bigger tubs have more surface area. Would I be able to pull the same yield with less spawn on the first flush? Just wondering if surface area is a limiting factor and perhaps I can stretch my grain a little further if I only plan on a 1 flush and done grow cycle?
The answer is that the amount of water you can get into the fruits, which is a function of the size of the reservoir and the surface area to support the growth. The difference between a 15quart and a 66 quart is the amount of water in the sub, and the surface area, not just the surface area alone.
If you have a bunch of water weight left over its because the culture isn't very efficient at moving the water from sub to fruit, its obviously efficient at utilizing your available surface area but not moving water. For that particular culture anyways.
I use Pasty's metric as a standard. To consider my culture worth slanting I want it to move 70% of the water into the fruit. So if I have 5 liters which is 5kgrams, 70% of that is 3500 wet grams for a first flush.
Edit*
So do you know how much you get in wet grams first flush with that culture? If so, whats the percentage of water that you're moving? If it's not a decent amount then you may just need to hunt for another culture.

I know its a small sample size but I have had very similar first flush yields with 2 clones of very different varieties grown in the same size tub. I haven't measured wet weight so I don't know what the actual percentage of water used.

I ran into the same problem. The sub was 4 inches deep and had plenty of water. I just assumed it was genetic and didn't even bother with any clones despite the canopy.

Alrighty, so...it sounds like your issue is a culture that is inefficient at moving water. You have a dense fruiter but its leaving a bunch of water in the sub.
I've got a toc clone that's super dense but way too light. I hate having a canopy that dries out to nothing.

So you are saying that the better the culture is at moving water, the more dry material the tub will produce in a single flush?

Is it possible that packing the sub too tightly will make it harder for the culture to pull water?

Not sure, never tried. Somebody just posted a grow where it was weighed down by another tub though, looked like he got a decent pinset and flush.

I think I just had an "AH HA!" moment. Is this why rhyzomorpic myc tends to produce better yields? That is, being the system by which the fungus moves water\nutes, more rhyzo means more efficient mobility of water thus more and\or bigger fruits.
