"I always thought the idea of liquid mycelium culture was so you could use it to innoculate solid substrates more effectively."
Generally that's the way of it, but I was looking at it this way. It takes 3 - 4 weeks of fussing and waiting for the possibility of good fruiting. It takes about 1 maybe 2 weeks for a large amount of mycelia with minimal effort. The mycelia (at least under non-submerged conditions) still contain a significant content of psilo. It would likely be a lot easier and probably much more efficient to simply use the mycelia, either dry it and pack it into capsules or extract the goodies via ethyl alcohol and use as such. The easiest way to do this would be with submerged cultures, having to solid organic matter messing up the product. Plus, to continue production all one needs to do is aseptically add mycelia to a new jar of media. It would be a continuous operation that could fit into a closet and require minimal effort with mondo results. Maybe it's too good to be true, I mean, spores are easy to get as well as the rest of the supplies.
