c02/o2 exchange
    #3555688 - 12/29/04 04:13 AM (12 years, 7 months ago)

I was thinking about a post ticktock made awhile back....co2 is heavier than air and is typically swpet/moved by wind or some type of force concerning air...Well...if that's so, then why don't we flip our jars over to let the co2 fall out? Obvisouly there's no great movement inside of the jar so then how does the c02 come out? Just a thought...

Flipping grain jars is a bad idea because moisture can pool up on the tyvek and contaminate it..I had it happen to a few jars before..the myc ended up ok since only the top of the tyvek contamed..PF Tek jars get flipped alot when they stall though for better drainage of water and co2.

To better describe exchanges...when incubating co2 is actually good and needed...however mycelium will keep producing it and if theres no release the pressure will build up...thats why soda cans have the bottom punched in...if it goes bad the bad stuff inside produces gases and will push the bottom of the lid out..same with any pop top lids...if it were sealed this would happen. This is calle gas exchange and is only releasing of excess buildup gasses that are forced out by the pressure of the co2 being created in the jar.

Once fruiting though you want almost no co2...lots and lots of fresh air exchange..which is different from gas exchange...not just the release of excess gases but actually pumping fresh air in.
