One 4oz bag of fully colonized King Oyster mushroom sawdust spawn ready to go. The quantity is enough to inoculate one hardwood log 40" long and 2-5" in diameter.
sawdust spawn consist of mycelium grown into hardwood sawdust. You will need a drill bit size 7/16" with 7/16" stop collar, or if you have a 12 mm bit with stop that will work.
Note: sawdust spawn is prone to drying out pretty fast, after packing the spawn into your holes you want to seal the holes with wax as soon as possible, you can use cheese wax, beeswax, or paraffin wax to seal the holes, you want to drill your holes1 inch deep. This is where the stop collar comes in handy, See our direction manual for detailed inoculation instructions.
