noob mushroom grower seeking help

the CO2 makes the process work. If you expose your mycelium to light before full colonization you don't have much of a problem,it is only afterward when you are looking to get everything to happen at once. Mycelium makes HUGE amounts of CO2, so much that you could elevate the CO2 of a room with a couple of bags of mycelium for weeks. Your jars will be in the 10,000 ppm or more range - rememer CO2 is heavier than air. When I am working with jars and the jar is colonized I will literaly "pour" the co2 out of the jar. I gather you are working with thos pucks or cakes - if you had grain you would be able to shake them and speed up the process greatly.

Yea I'm working with verm cakes so shaking won't do anything. Next batch I'm going to try popcorn so that might work. Where would one obtain large amounts of co2

As I said, you don't need it, the mycelium produces it in huge amounts, when the ppm count goes down to 1000 or so is when they like to start pinning.
