Interesting, I grow Oyster mushrooms from used coffee beans. I really like giving an extra purpose to so many beans consumed.

- 1827163 3y agoI have a whole 70 litre dust bin that contains spawn and waste organic matter, and it's all turned white and fluffy as the mycelium has colonized everything. And once it's full I can then use the mycelium to start even more colonies on collected tree leaves and branches. It kind of grows exponentially in size. I just keep producing more and more of it.... When you grow large quantities of mycelium this way, it generates its own internal heat, I've found it to be warm inside. So that makes it grow faster than it would if it were at ambient temperature. Also the large amount of spawn easily overruns any other fungi that might contaminate the bin, such as green mold, before it has time to spread. The oyster mushroom fungus is a very aggressive colonizer which will eventually outrun green mold with time, but this can take a while.
- tstrimple 3y agoAll of my mushroom experiments have ended in mold. I wonder if I just need a more aggressive fungi.
- 1827163 3y agoIncrease the ratio of spawn to substrate, and ensure that it's mixed very evenly, as that will increase the surface area for growth. So it will colonize faster. If you're growing it in a jar, ensure that you make a couple of tiny airholes in the lid. The fungus needs oxygen to grow. But if the holes are too big then fungus gnats can get in, and you will find maggots in the mycelium, which you don't wont. Also if you have a moldy jar, leave it for a couple of months. You might find the mushroom fungus has overrun the mold eventually. And finally, Oyster mushrooms can't grow on pine woodchips, by the way.
