Could you please go into more detail about the NaOH CO2 scavenger you used?

If you want to test this out, the easiest and safest way would be to place your cased trays in a tub with the lid on with 1/2" of water on the bottom. Bake 50-100 grams of regular baking soda at 150 C / 300 F for 15 minutes (to turn it into sodium carbonate), let it cool for a minute or two and dissolve it in the bottom tub water. Some minimal fae may still help/be required, like opening the lid once a day or something.

I can go into the theory, but I don't want to bore anyone. 100 grams of heat-treated baking soda has a capacity to absorb 41 grams of CO2 (around 20 liters), which is plenty. In the wild, pans grow in grass fields where at ground level the CO2 is probably less than 200 PPM and there's wind. NaOH can absorb 2 times more CO2 than hreat-treated baking soda(hardly a significant advantage), but is nasty stuff you don't want to touch your skin. I just use it because my supermarket sells a quart of drain cleaner liquid (31% NaOH solution) for like a dollar. This method can be a game changer for fruiting woodlovers indoors in the fridge, but that's a topic for another thread


Here's a photo from an old research paper where they used this system for fruiting button mushrooms in a sealed chamber: They used calcium oxide granules instead because it's more suitable for being able to autoclave the whole thing (it's not hygroscopic and requires no water for the CO2 scavenging reaction), not because it's better than NaOH or baking soda:

Hello buddies:() I have been struggling to learn how pans behave since a while now

I put some spores in agar and they filled the plate before I even remember to take look at it
Like in 10 days, now I have bo clue which part looks more promising, some parts are flat and some fluffy , there is a mess in there !

Is there an experienced eye that can give me some insight please ?
