Help on contams and technique

[Mosach]

I'm wanting to minimize the dreaded Green mold attacking my Bins.
I'll describe the process and you can tell me if I'm doing something wrong or need to change.

The grain I use is wild bird seed which is innoculated with Liquid Culture. I have no problems with this because I can safely maintain 0% contamination.

I wash bins down with soap and water and dry. I do not use a disinfectent because I found it causes Rosecomb. Mycellium is scooped into the bins, then covered with a 50/50 coir/poo mix.

That is left to colonize until 80-90 %. This is then covered with a 50/50 peat/verm layer. This is allowed to colonize and then fruiting is initiated. Sometimes I get a contam at this time, other times I get contamed after a flush. The peat/poo/verm and coir are pasturized before being added.

I wash my hands and spray a disinfectent in area.

I read about adding lime. I have dolomatic lime. I know its not the right lime because of the magnesium. Do I need it though? Will it minimize contams or just make them better?

The fruiting chambers have a mister and air pump, so nice and humid. There is also a pc fan to air out the bins.

Thanks for the help!

get rid of the peat and you won't need lime.
it's 50/50 poo/coir bulk, right ?
you don't really need a casing
and since that's when/where the trich hits
i'd just skip the casing.
and increase your fresh air exchanges too,
trich loves stagnant air.
