Composting will depend on mesophilic organisms that function best at 68 F to 113 F (20 C to 45 C)—so the temperature is an important consideration. That’s how some gadgets have heating components and why composting bogs with out heaters can be affected by ambient temperatures.

In non-tropical areas, the temperature will normally drop beneath among the many most interesting temperatures for mesophilic organisms and the composting course of will sluggish considerably and even stop.
