For these two varieties, we strongly recommend heat-treating and incubating your logs in filter-patch bags to provide a blank slate for your desired species. Each bag fits a 1'-long, 8"-diameter log segment. One bag of Sawdust Spawn will inoculate about 10 log segments—you’ll need one bag per segment. The 0.5-micron filter allows for ample gas exchange.

More detailed instructions for heat-treating logs will come with your order. Bag is 3mil thick polypropylene, 10x5x24". Pack of 10 bags.
