Fair enough. What is your intake humidity? I'm still designing and taking notes for my fruiting project. My intake humidity should be around 50-60%, so it will need to be humidified to 80%.
Is there an easy way to measure the level of O2 inside the setup?

For my flat joker boxes, I just filled them with water and tipped them. Water comes streaming out, and growth looks normal.
I use that method to estimate GE, lid on.

I don't measure 02.. I have an exhaust port with a duct fan pushing air out of my fruiting chamber about 12inches off the ground...the low level ensures that all CO2 (as it is heavier than oxygen) is forced out. The negative air pressure ensures all air is exchanged

What specifically do you look for/notice in mycelium growth/colonization of tubs to determine if FAE is lacking?

These are all bags placed directly above the exhaust port

These are some fruits before the exhaust port was installed...you can see the. Drastic difference..these. Were so desperate for 02 that they reached sky high unlike the first pic where they flourish

It's an important concept to grasp that mycelium breathes the same way we do...they take in Oxygen and expel carbon dioxide. Co2 is heavier than air so it will sink to the bottom of a closed system. Systems lacking fresh air exchange are notable for having: No to poor fruiting quantity Fruitbodies that grow straight up as though they are trying to get their heads above water (closer to the oxygen) Aereal mycelial growth etc...
Not to mention water evaporating off the substrate is a primary pinning trigger so you always want moving air in your growing environment which is why the shoe boxes don't fruit as prolifically as a well dialed in monotub...the tight stuffing at the bottom and the loose stuffing at the top creates a negative air pressure effect...kind of like when you crack a window in your bedroom and your door slams shut...

Ok I worry about fae in my grow room because there is not a lot of air current in there except when I go in. I have my shoebox lids cracked is all. Mycelial growth in my boxes is somewhat fuzzy I guess. Is aerial mycelium fuzzy or more like spikes I've seen in pics?
It's really difficult to look at pics of what is said to be healthy growth and compare to my own since lighting and camera perspective makes a big difference in how it looks in a pic. Seems pictures dont capture very well what it looks like in person. I've taken 3 different pics of the same tub before with 3 different lighting sources and they all look different and the differences can be quite drastic

@Mycologist217
Indeed with the O2 (oxygen), I can prove this in various ways. Even Cubensis thrives on O2 and CO2 exchange. I also found good light makes a difference, and Golden oyster is a good indicator that both are ideal.
In medium FAE and low light conditions, it stretched to O2, and produced limited colour. The same block outdoors, with tons of light, O2 and water, it was much better.

----
Mycelium that can decay phenols, should be utilizing and distributing oxygen more than those who cannot. This is because phenols (such as lignin or tannins) require oxygen to decay (oxidize) properly.
Mycelium also uptake solubles and oxidize them in an area with higher O2 (see here). Note: Cubensis does oxidize phenols, see my Cubensis log here.
----
Did you know you can recycle and benefit from expelled CO2? (see here). You can find more data on various topics in my Journal (here).

Temperature is also key.with golden Oysters. They are a tropical species.that thrives best in higher fruiting temps (ie 85F) as opposed to the default 76 for most domestic species...I gave a trial run with several of the exotic oysters in my chamber and the results weren't great:

Very very small fruitbodies but bountiful quantity...very bad taste...you are definitely on to something with the lighting issue there. My chamber runs on a 12/12 lighting using florescent grow lamps

Good point, it was 22-24°C indoors, and ~26°C outdoors. These fruited @ 10°C - 70% Rh:

Edit: All of my oyster grows have tasted great so far.

Shaking is much faster. Depends on how full your plate is honestly

Since we where talking about containers and O2 exchange, I now use these, and do the grow-up style spawning method. As the mycelium grows-up it detects higher O2, and changes in growth, it produces a surface block.
Fruiting occurs in the areas with highest O2, again the surface, usually no side pinning. Unmodified produces good growth even for high oxygen recipes.
----
Key: Ko = King oyster, To = Tarragon oyster.
[Ko]: Colonizing, obvious growth change around the surface area (highest O2).

[To]: Consolidated, with a very obvious surface block, no side pinning.

[Ko]: Surface fruiting, was to warm and dry for them.

[To]: Fruiting with the lid on, left too long.


----
The recipes being used are test's. No visible metabolites.

Speaking of shoeboxes. Shiitake don't really need a bag even they'll do all right indoors with a misting a day or so.

Interesting. That would be a nice edible display for the holidays.

I must have missed a lot what is Hwfp? For my shiitake I just use oak saw dust, chicken shit, and wheat bran.
