A sun shield for your mushroom logs

I had some mushroom logs that I drilled.  They never fruited.  I decided that they probably got dried out by the sun.  

I made a new strategy.  I put them under some stairs, which I thought would keep them out of the sun.  What I didn't realize is that since the Earth rotates around the Sun, there could be a window where they bake in the sun. I checked it and they were getting an hour and a half of bright sun just before noon.  Not good.

I found this old shower curtain and decided to hang it on the side of the doorway, so that even during that period, the sun won't shine on the mushrooms.  At any time, I can lift it up to access the mushrooms.

That should help.
Back when we were plugging logs we kept them in a shade house and also covered with cloth...old cotton blankets if we had them to keep the logs from drying too much.
They sell 'blankets' called fruiting blankets I think but any natural material that lets rain through will work...need to remove periodically to inspect the logs.

I do use some old tarps to cover the stacks of logs for the one or two month period in the summer when the sun will peek around and shine on the logs on the north side of the house.
