I'm mostly making it as I go. I just made this design so you can see what I'm after. I haven't added temperature control because my place is always above 20C, which is ideal to grow mushrooms, so I just need to keep the humidity high, the air clean and provide light for 16h a day.

The controller box will have a breadboard with an arduino nano, an RTC module to keep the time accurately and three mosfets inside, each mosfet will switch on and off each thing depending on the time of the day or the humidity inside the box. I could just make a PCB, but for a one-off thing I'd rather just cram everything into the box.

I'll be growing lion's mane, you just buy a syringe with spores on ebay and put the spores in an sterile medium in which they can grow. Reading online it seems the substrate for lions mane is made out of hardwood pellets and wheat bran. I've seen people growing them in bags, but it'd rather put the substrate in jars because it's easier to sterilize all the jars inside a pressure cooker before putting the spores in. The main problem is contamination, things can get moldy in no time. I've grown mushrooms before and by the end of the month the substrate was all moldy and had to be thrown out. Growing mushrooms is quite easy and they usually grow very fast, the main problem as I said is contamination. Hopefully the filter will provide clean air and make the substrate last longer, having multiple batches and better yields before cleaning everything and starting again.

I've still have to finish the arduino sketch, but I'll post updates along the way.
