Hi Philip,
high CO2 levels in incubation should be to your advantage as it will stop/ delay any pinning. Then once fully incubated and hung into the fruiting room they’ll be off like a shot. I think for Oyster the upper limit is somewhere near 20,000 ppm so no problem there.
I would not set the computerised system to come on too much as Co2 levels and controlling co2 is the key to regular and consistent production. I’d love to hear more about how you’re approaching this!
Best wishes,
Eric
