I understand that you are reading the zones however we are expecting a harsh winter, the worst in a decade that's a 100 yrs I recall my grandfather telling me that he had to heat the fuel tanks on the lorries as they where freezing... so this year could be that bad a waxing occurs at -15 to -22 so may have a problem there.
Can you please advise how long seeds need cold for, I have put some in the freezer, as I read that the yields increase by 60%...
Also can you name the brand that you use for spraying I know you don't use it... but it would be nice to know as I know there's difference between provardo types etc
The Sphagnum Moss idea makes sense since it contains iodine which is sterile, thus keeping your rhizome free of moulds etc
Have you been able to identify the moulds, that you have experienced?.
