if you get the dry crumbly filterpress off the top of the piles you can use it staright away,but if not make sure its broken down into small pices with a shovel and spread out to let dry,cause sh'll burn the crap out of anything you put in ther, other wise just grow straight into pure filterpress wioht some musie compost mixed through for airation.
