next step

First test with the geosmin odor and a fog machine made!
For now, I can say that there is a big delay between the moment the fog with smell comes out and the time when you can start smelling the geosmin. BUT, the smell stays for very long time in the space once the smoke is gone.

Streptomyces coelicolor

It seems the bacteria Streptomyces coelicolor is the main cause for the geosmin odor.

Some questions that give some base to my research:

*** Do we try to portrait nature because it makes us happy?
**** Are we happy when we are gardening because we smell the bacteries in the earth?
***** If so, would geosmin make us feel better in a non natural enviroment?
