Default Hydroponic Mushrooms

I don't plan on doing this right away but I just cant get this idea out of my head about growing Hydroponic Mushrooms. They grow in the dark so there would be no need for lighting, cutting production costs (white asparagus grows in the dark also).

I am thinking of something like using short and wide containers, used as a drip system. The return line would be at the bottom of the containers with a Styrofoam spacers to keep everything from sitting in the inevitable small amount of water in the bottom. Then placing a screen on that, then line it with something like cheesecloth to keep the growing medium from falling through. I would use coco fiber for the growing medium because it has the texture most like soft dirt, and is very well at holding the moisture. Not sure if these trays should be covered yet or not, like a seed tray are. But that should not be hard to figure out.

I know when growing fungus that sterilization is extremely important, so everything will be sterilized. The coco fiber and cheese cloth will be boiled because I don't want to use chemicals there, and absolute no chemicals that have a fungicide can be used anywhere. I would also use a hepa filter air purifier in the room to filter out airborne spores that could make their way into the growing medium. It just so happens that the hepa filter air purifiers are quite common at the thrift stores here in town (we have at least 4 of them), and can usually pick one up for $20 or $30.

My biggest concern is the nutrient requirements. Way back when, we sent away for magic mushroom spores. They came with directions, these directions included using organic rye for the soil (organic is free from fungicides). I am not sure why. Was it more rich in nutrients than soil? Was it because of the bacterias as it decayed. Was that only for that type of mushroom? After all mushrooms generally grow in cow manure. Witch leads me to wonder what the pH level should be. I'm sure that not all mushrooms have the same nutrient requirements.

That also reminds me about something I had thought of a long time ago, growing truffles. If I could figure out how to grow them in captivity I could potentially make a fortune. As far as I know nobody has done it successfully, even in soil. I'm not sure why, but I guess nobody else dose either. I image it would be quite difficult to get a hold of the spores, and probably quite expensive. Because they only grow in nature I guess I would need to buy the truffles to get the spores.
