 Optimum O2 level for cubensis, and other species?

The atmosphere is 21% oxygen. How would supplementing the atmosphere of a terrarium with oxygen affect the growth of the mushrooms?
It's a known fact that CO2 supplementation can significantly increase the growth rate of plants.

i really wish i could find the source,
but i remember seeing on i believe fanaticus.com once this same thing your talking about. The resulting mushrooms (on PF cakes) were HUGE, the stems were easily twice as large as normal, caps being approximately the same size. This leads to the question, if the increased O2 would lead to degradation of psilo compounds, who knows. I'll look around, maybe someone else would have more input, I believe its worth looking into.

I would have to believe that as long as the integrity of the fruit/mycellium is maintained, the overall oxygen content wouldn't make a difference in regards to degradation...
If the cells were opened to atmosphere, than yeah, they'd probably degrade faster than my ex's mental state.
Damage done during picking could be easily contained with a CO2 flood of the chamber....
Interesting idea.

Might not be a bad idea to starve of oxygen before harvest.

Probably a good idea....would lower O2 concentrations, and throw the mycellium back into a colonizing phase, preparing it to lose fruits with less loss of nutrients.
If you've got a good way to test, i'd say up the O2 concentration to about 40%....that should be a good mark.

at one time i had a terranium with a casing. with it was a salvia d plant.
i'm not sure if its the large substrate with small surface area, or the oxygen from the plant, or maybe salvinorim somehow got metabolized by the shrooms (?).
but these shrooms were extremly potent, X3 than normal.

would it be possible to rig a chamber with an inlet tube that injects C02 from a tank? You could have it hooked to a solenoid and then to a timer. Would that be a good idea?

If you guys want Co2 in your chambers then stick a small green plant in there. Plants create 02 and C02 when they synthesize under light, but when you turn the lights off in that terrarium with the plant in there, the 02 production will stop and the C02 production will rise. Little tid-bit from my professor. I guess in order to control the concentration of C02 you'd want to experiemtn with the size of the plant you stick in there. Good luck.

Here's an interesting way to test this. Simple electrolysis experiment. Have a jar of water in the terrarium, and get a leftover ac-dc adapter, cut the end off, seperate the wires, unsheath them like a cm, and the put them in the water jar(wires not touching). The resulting reaction will be production of oxyden(and hydrogen) as the water will seperate into its component parts. Do not have an airtight terrarium, as you don't want a high concentration of explosive gasses. The higher power the adapter, the greater the effect. This way you could theoretically increase th oxygen content within your localized atmosphere.

I thought about electrolysis. Seems something would have to be done with the Hydrogen. It would have to be at least vented seperate from the Oxygen. Otherwise you'd be asking for trouble.

I think the early deep-divers method of atmosphere renewal is probably the best way to go.....the chemical is cheap, and easily replaceable, with no major side effects on atmospheric composition....
All the new chemical breathers use some hard to get shtuff.

Hardly at all. There are already more than 20% oxygen in air, as you stated yourself.

Indeed, but there are only about 0.03% of CO2 in normal air. If you raise this to only 1%, you got a 33 fold rise in concentration.
Try this with O2...

Oxygen could be increased up to 5 times normal. That could be significant. Untill someone performs an experiment and there are real numbers to look at, I guess we're just pissin' in the wind.

rebreathers use a mixture of sodium hydroxide, and calcium hydroxide, which removes the CO2.

Mushroom mycelium can fix CO2, also. Some CO2 actually speeds up growth.

Studies have been done with other fungus. The oxygen requirements are extremely low for mushrooms. WAY less then what is in the atmosphere.

Why exactly is air exchange so important then?

Might a higher oxygen concentration reduce risk of contamination? That is part of the air exchange I think. Stagnant air and low oxygen content are favorable conditions for unwanted organisms. I'm not sure though.

to reduce CO2 at the casing soil surface, and increase the evaporation rate at the same spot.

i had the assumption it was related to the amount of co2. more co2, to the organism, might be a sign that there are too many mushrooms for the location(maybe through evolution, the organisms that were all aggressive suffocated themselves leaving no offspring?) this would be similar to how canabis and other photosynths determine a guestimate of their proximity to other red spectrum absorbing organisms. our friends are so selfless!
