Not really.Hey @aart do you ever have a problem with the chips molding? We are in almost a tropical environment because we’re at the bottom of a holler. We’ve got piles of wood chips around the property (we are a 150+ acre hardwood tree farm) but they break down quickly and do get moldy.
I do take care to get the outer layer from the pile and spread it thinly(~1-2") in the run.
Adding other dry plant material can help dry out any growth(not all of which are 'bad').
