CO2 production peaks during your spawn run through the grains, then again as your bulk substrate is colonizing. This is why we provide gas exchange for our colonizing jars, and a loose fitting cover such as foil for our colonizing bulk substrates..

You fan your terrarium much more for air exchange to stimulate pinning and also to keep contaminants at bay. It's important to understand the difference.

During the inital spore germination phase you want your jars to be high in CO2.

10,000ppm's - a high CO2 at the inital stages of colonization will help mycellium consume the cake. Gas exchanges must occure however so that is why we use tyvek/polyfill filters for our jars. mycellium uses the CO2 to break down and convert the nutrients into digestable food.

Once colonization peaks at around 75% finish time in your jars a drop to 5,000ppm's will help quickly finish up colonization.

This is obviously very in-practical advice since you'd need a CO2 meter and know how to properlly modify one in order to get readings in your jars (I have got to this extent mainly because I actually had one available to me) but yes...that explains the importence of air/gas exchange during colonization.

and RR covered fruiting, good luck.
