I am fairly new but I think I might have some useful info... I use a 10g 'maid with perl also and I have 6 cakes in each... I find fanning 3-5 times a day works fine...

I'm not sure if you are misting your cakes or not but you should not be... If the caos are just wet from humidification then I would say just fan a few more times a day but don't take them out of the tub... Just spraying the walls once before you go to sleep is fine...

Sorry if I misunderstood... M

Hi Marvin,
Thanks for your reply. I presume that 10g means 10 US gallons which is about 38 litres. That's a little over 6 litres per cake or 1.6 US gallons. So 6 cakes in a 10 gallon container with perlite and fanned 3-5 times per day works cool. That's nice to know as a reference point.
I'm not misting the cakes at all. Paul Stamets in "The Mushroom Cultivator" says that if humidity is too high during the fruiting stage (not pinning stage) the mushrooms will abort or at least grow very slowly. I've read about mushrooms growing from cakes directly on the perlite being quite soggy and rotting. Maybe if they were allowed to transpire more they would fruit ok. Maybe the amount of airing needed depends on the moisture content of the substrate or casing. I've read that cased grain needs a lower humidity than cakes. Will shrooms on cased grain abort if the humidity is too high? Do aborted pins on grain due to high humidity look wet? It's hard to separate the carbon dioxide issue from the mushroom transpiration issue because fanning solves both problems!
