It says they are "birch plugs" and none of mine are birch. Would that matter?
It could matter with this particular specie, but this is what they write about Maitake - Hen of the woods:
"Will grow on a wide range of hardwood logs & stumps and some conifers: oak, elm, maple, sycamore, beech, plum, peach, hemlock, and many others."
So it's probably worth a try. Just keep the log moist.
And most mushrooms like it warm. Some need to grow in a dark place though, so the pantry might be a good idea. Just check the descriptions and I'm sure you'll find something that would be worth trying out.
