IMO3 pile indoors (living area)
Hi KNF friends.
So i was waiting for nicer weather to mix an IMO 3 pile outdoors, but yesterday, may 9th we got hit with another foot of snow. So Ive decided to mix my pile indoors on my 4x4 no till garden bed that i have in a basement room in my house. So far so good, the pile warmed up and ive just turned it 24hrs after mixing the pile as it was getting warmer. As i turned the pile and i was admiring all the nice white fuzz forming on the soil around the pile, I wondered about the safety behind innoculating microbes indoors. My room isnt equipped with outdoor venting, so some "fumes" could make its way into our lungs and potentially our newborn baby's room. Any thoughts or words of reassurances? Thanks in advance.

White fuzz on the pile is the expected sign. Visible white fungi covering the top layer signal successful inoculation. (Unravelling the Mysteries of KNF, p. 59)
Ventilation is the point to watch. Cho's rice bran recipe for massive IMO cultivation says to work on a soil floor, not concrete, in a place with good ventilation. (Cho, Recipe, p. 15) A room with no outdoor venting does not match that advice. (Cho, Recipe, p. 15)
Heat and smell tell you how the pile is doing:
- Keep the pile below 120F and check it morning and evening. (Cho's Solutions, p. 18)
- Turning drops the pile temperature by about 10F. (Cho's Solutions, p. 18)
- Finished IMO3 smells like forest floor. An asphalt smell means it got too hot. (Cho's Solutions, p. 18)
The library says nothing about fumes, spores, or risk to a newborn. That question needs Drake's own look at your room.
