if you can get to a pressure cooker, its quite simple to sterilize and innoculate mason jars. they store easily and the glass works well in fluid filled incubators.
you can use dowels or wood chips (since yours are hardwood decomposing right?) in the jars and a syringe works well with the plastic lids.
