Planning kindling production

[John Barleycorn]

I have the chance of a large amount of pine & am thinking of hiring a kindling machine for a few days.

However I have foreseen a problem in drying it.

I currently make a small amount of kindling by hand, because you can always flog a customer a few bags when you deliver a load of logs.

A couple of Scots pine logs felled three weeks ago have already developed blue stain, in fact its dark grey/black. I can understand customers being prejudiced against black kindling (without it being a diversity issue !)

Even the unseasoned "green" pine kindling in bags can develop a white surface mould unless it is dried in a very good airflow or sun.

Is this problem caused by summer felling ?

High sap/sugar content and warm temperatures ?

How can I prevent it if I get blue/black stain attempting to dry logs, or white mould in the bag ?

I could make & store a few thousand bags in the shed, but I think they could be unsaleable.

No I dont have a pollytunnel.
