We are clearly fast approaching the point of establishing the maximum production capacity of this fruiting chamber. The blobby mushrooms are all young Hericium americanum.
The CO2 level is still running a little high (650 ppm) but I’m hoping to have that dialed in within the next couple of days by adding a larger vent fan (replacing one of the existing ones – a 4″- with a 7-inch inline exhast fan).
RIght now it is where we want (between 450-500 ppm) only until the chamber gets more than half way full. Preventing the massive spore load from clogging the insect screening has also become a recurrent maintenance task as the accumulation of spores plays a major role in interferring with good air exchange. The air inside of the fruiting chamber is completely replaced with fresh air six times every hour.
