Hi brother, 👋 peace. Fire needs 3 things in order happen. Cut out any 1 of the 3 and it can't happen. Oxygen, heat, fuel.
Bacteria, disease, pestilence require 3 things also. Moisture, Food and Time. You must make sure it does not get all 3 for too long.
Moisture is ok so long as drainage is good. But remember those buds will absorb alot of moisture left outside, beware if it's due to call for rain multiple days in a row. Shed wouldn't hurt at night.
