Ok so this would be the 4th batch of cakes that sat in the camber for 4 months with out doing a dang thing. any advice would be more than appreciated.

basically a run down:

-golden teacher

-pf cake

-birthed two weeks after 100% colonization all 4 batches

-dunked an roll in verm

-perlite to hold humidity in a low flow shot gun chamber(the relative humidity out side chamber is 9%)

- fanned 7-8 times per day

-misted 4-6 times per day

pretty much what happens is the cakes either dont pin at all or they pin alittle an dont much much further and just "pause" for 3-4 months then mold takes over at that point and so does ones patience,

any idea what could be going wrong?
