I am not good at chemistry but i know magic mushrooms and have had that hobby for quite a while.

The idea of adding stuff into the growing substrate like Phalaris grass or tryphtophan does NOT work.

There must be something more to it.

This idea is constantly discussed at the mushroom sites and has been tried more than 1000 times.

There are a few reports that say it works but they are wrong.

If it would have worked all would have used this method by now.
