propagating mushroom spawn - Yellow Oyster

Good Evening,

I had some left over saw dust with some spores in the bag (Yellow Oyster). I gathered all that up and placed it cardboard that was boiled in water and cooled. I put the spawn mixture in layers of cardboard. i had 3 layers and the spawn sprinkled with in. I am not sure i had enough spawn to make this work. Tomorrow i will be doing another batch but adding some left over wooden spawn dowels. I put the little container in the dark. I hope to see white spawn growing in a few weeks! Here is my first picture.
