As if the growth chamber was not enough, I have now expanded into growing mushrooms. Peter gave me an oyster mushroom kit, and not being able to leave well enough alone I have started to try and propagate them.
There are lots of high tech and low tech methods, so starting somewhere mid-tech and will see how it goes.
I took a bit of mycelium from the block and put it in a coffee grounds/saw dust mix, but it just seemed to sit there and not do much. The other day I stuck it on top of one of my Raspberry Pi computers (to get a little heat), and now I am seeing some new threads of mycelium beginning to travel out and about. So now I have dug out an old seed germination heater and will start to get serious about this.
Next project giant outdoor mushrooms!
