A question in the mushrooms response to increased oxygen.
    #9202837 - 11/07/08 03:41 PM (15 years, 3 months ago)

Say you use a concentration of hydrgogen peroxide in a humid air exchange to increase oxygen as well as humidity in your fruiting chamber.  Are mushrooms adept enough at absorbing oxygen to have noticeable increased growth?  To what extent are a mushrooms growth parameters effected by air?  I know marijuana growers supplement Co2 to potentially double their yield.  So I got curious about mushrooms abilities to perform respiration.

Imagine aquarium air pump with difussion device (nonreactive metal) was dropped into a jar a slightly higher than 3% concentration has anyone tried anything like this?  I have only seen things on pure O2.

That is a thread in the Advanced Cultivation forum about H2O2 use.  Personally, I use H2O2 to disinfect the humidity supply in my FC and supply extra oxygen, but I have not really noticed a difference.

Duly noted was only searching cultivation.

With shrooms you'll want to add a lot of actual air, not just rely on hydrogen peroxide.  Growth can suffer from a lack of enough air. Pins might not form, they might abort, or they might just be tiny.    Also, not enough fresh air exchanges will support contamination moreso than just leaving the lid of a chamber off.  Every time someone gets cobweb it's usually from being too paranoid about letting air in, then the cobweb eats all the shroom's nutrients so it's not much point in killing it.

Lots of shrooms grown in a low fae environment, will have small caps as well. More air = robust shrooms with larger caps, and less rate of contamination.

Maybe you misunderstood my proposition.  It would be something like this.  Imagine a one quart mason jar if you will with two holes in the lid.  Through each hole is running a line of 1/4 inch aquarium type tubing sealed with some silicone. One stops roughly one inch on the underside of lid.  The other connects to a nonreactive metal or plastic diffusion device (percolator similar to the rocks used in aquarium).  The line connecting to the percolator would of course be connected to a small aquarium pump that would be set in the open environment roughly 3.5 feet off the ground.  The Line not connecting to the percolator would be connecting to a hole again sealed with silicone either midway or high on the fruiting chamber wall to increase the down draft expelling any co2 build up.  The jar housing the perc. assembly would be filled roughly 3/4ths full with some concentration of hydrogen peroxide and water.  I was thinking of submerging this jar further in a small recepticle warmed by an aquarium heater to moderate a constant 75 degrees as the place is already dropping to mid to low 60s at night.

H2O2 breaks down at a slow rate at room temperature but if you incorporated some peroxidase into the mix it would make it more reactive...  My question was more about the respiration potential of mushrooms than anything.  Is there any research as to what is the maximum ppm of oxygen they can absorb?  Or atleast estimates?

We've had many members including myself experiment over the years with increased O2 in fruiting chambers.  We've tried liquid oxygen, tanks, concentrators, and peroxide, with little to zero discernible effect.

I had to stop there, way over my head. Lol
