Anyone experimented with pure oxygen for fruiting chambers?
    #7532935 - 10/18/07 08:15 PM (16 years, 3 months ago)

So i am thinking of piping pure oxygen through a air stone into my fruiting chamber and and limiting ventalation to just a few Ty-vek filtered holes. in doing this it would bring a very rich humid oxygen into the chamber... kind of a mushie steroid. any ideas on this? i think it would have great effect. What do you think?

Uh, why?

Mushrooms don't need intense levels of oxygen, and it's not even beneficial. The fresh air exchange is to eliminate CO2, not provide oxygen.

Uh, Brainiac, I think plants would like additional CO2. Not oxygen.

No, no, no. Plants use CO2 to make O2. Mush. are different they do not participate in photosynthesis. All they need is a fresh air supply nothing more.

but were not talking about plants the op wants to know how it will benifeit shroomies not plants i think if you placed the holes at the bottom and pumped oxygen through the top it would push the co2 out more effeitly and then the level of oxygen would promote healthy shrooms but i think thye also need nitrogen and theother things we need to breathe

fresh air supply what kinda air

Sorry, sounded better before I type it.:nonono:

Plants love co2.

Some people do use pure oxygen in brewing to make yeast more active.
Just don't have a flame around pure oxygen.

Yeah, oxygen is generally used in the fermentation process to augment reproduction of yeast particularly when you're recycling spent yeast from a previous brew (the lipid content is extremely low; it needs to reproduce). We homebrewers just thrash around the wort for a while :smile:

Milkman, by "fresh air" we mean that with a low CO2 concentration. Mushroom mycelium produces CO2 as a byproduct. From the Mushroom Cultivator (Stamets), p157

"Fresh air also removes high of carbon dioxide and other metabolic gases from the room. Since Agaricus brunnescens does not pin properly at CO2 concentrations above 2000 ppm, lowering the carbon dioxide content of the room's air to under 2000 ppm is critical. The inhibitory effect of carbon dioxide on mushroom formation gives Agaricus growers a high degree of control over the pinning process. Not until carbon dioxide is removed will pinheads form. If carbon dioxide levels remain high, the mycelium will totally cover the casing surface, a condition called overlay."

The natural level level of CO2 in the air is about 300ppm. FAE is used to lower this, and prevent CO2-loving contaminants like trich.

Pure O2 has no benefit to mushrooms.

It could be interesting to give a try ...

but instead of using an EAN100 you could try something lighter like EAN32 or EAN36 or EAN40.

That idea has been around my head too.

im so tired of this question coming up...
Pure O2 is TOXIC. Not to mention dangerous, expensive and pointless.

apparently all CO2 does is let the mushies know its time to go from vegetative to fruiting stages by sensing a drop in CO2 levels nothing more.

If O2 is not beneficial, then what do shrooms breathe? Nitrogen? Hydrogen? Surely they must like a certain mix in the air.

O2 is beneficial. The rate of gas exchange isn't really the limiting factor in mushroom growth. You're not growing plants.

They dont like CO2, they like humid air :-D

Now I was thinking if you set your little friends on racks to grow, with a small low speed fan blowing humidified air, you'd never have to fan. ever. ever. OR mist!

Using pure O2 is overkill (not beneficial at all) and pretty dangerous. Just put some holes in your FC and fan the stuff..
