Johnson Su is basically 18-20 day, no flip “borderline edge of slightly too hot for the beneficial microorganisms to survive” composting.
I don’t know, but I’d hazard a guess that it releases more methane than slow composting? Just by virtue of it driving the compost pile so hard. Who knows, maybe since it’s shorter time to harvest then more is released per day BUT for way fewer days. Just spitballing.
I just don’t want to flip my compost. I will water it lightly based on internal temp, day 4 or so I’ll remove the pipes and the compost will have set up enough to not collapse into the hole. This makes air chambers so the fast process stays aerobic instead of anaerobic/rotting. Tonight I’ll tarp it because it’s supposed to rain, and I don’t want the nutrient getting washed away or it getting truly water logged.
