Try dissolving yeast in warm water and adding sugar to allow the yeast to live.
The yeast will give off CO2, but your growroom will smell a little like a bakery
(or a brewery...). This can also attract insects.
I tried it for about a week and noticed little difference; I couldn't figure out
how to keep the insects from being attracted. Any brewers out there
have any ideas?
