science behind gas exchange in colonisation
    #7594309 - 11/04/07 11:57 AM (16 years, 2 months ago)

Hi guys, new on the forums. I have been doing a lot of reading as I want to know as much as I can possibly understand before my first grow as I have decided that going into the grow with a great deal of knowledge will probably aid me. I have searched the forums but my question hasn’t really been answered . I know that gas exchange in the colonisation stage is important because without it the mycelium would suffocate but what I would like to know is why would it? Is it because of too much co2 or because it doesn’t have enough of something else. Is oxygen actually need for mycelium colonisation? I have read posts by some people saying that it is and others saying that it isn’t, if it is need, what for? I know that co2 is given off when the mycelium brakes down what ever it is eating with enzymes may it be brown rice flower or wood, but is this co2 actually useful to the mycelium, I know that I high concentration of co2 stops pinning but does it actually aid the growth of the mycelium? and is too much co2 bad? From what I have read it’s a bit of a grey subject on weather or not mycelium needs oxygen but I have read some reports on rhizomorphs carrying oxygen as well as nutrients. I am quite confused, apart from the nutrients obtained from the ground does the mycelium actually need any gasses from the air to thrive? Sorry if this is a bit of an in depth post but I would be grateful for any answers. thanks

Mushroom mycelium consumes air, just like we do. It also produces CO2, apparently as a byproduct, just like us. One benefit of a high CO2 level during colonization, is that less of the actual carbon in the substrate is converted to CO2 gas. In other words, if you allowed too much fresh air during colonization, more of the substrate would be 'consumed' by the time the mycelium got to the fruiting stage.

A rapid and sudden decrease in the ambient CO2 levels is a pinning trigger in cultivation, so adding fresh air at the same time as full colonization and the other pinning triggers helps ensure a full, even flush.

Mushrooms perform aerobic respiration. Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of oxygen.

The balanced chemical equation is:
C6H12O6 + 6O2 -> 6CO2 + 6H2O + Energy

In short, to break down one sugar molecule you need 6 O2 molecules, which in turn produces 6 water molecules, 6 CO2 molecules, and releases energy.

Are we contributing to global warming by growing mushrooms? Oh my god...

When I colonize wood chips I would fill a heavy duty trash bag half way up with wood chips and add a few pounds of spawn and mix it up and tie the end in a knot. 2 twice a month I open it up and look at it and it colonizes rapidly

Stop experimenting half way through your first grow. Grow it to maturity, watch it, learn from it. Do this a few times then experiment with different ideas and figure out what works best for you.
