Charging the biochar in cold weather

I was wondering if this recent cold snap in the PNW might delay the inoculation process of my char. I mix my char 50/50 with worm castings and I feed it molasses and rock flour and keep it moist (not quite a slurry like I've seen people do). I noticed the other day that it was quite frosty. I don't have room to bring it inside but the cold weather doesn't usually stick around. Any advice or similar experiences?

Yeah, cold weather can slow down the inoculation process since the microbes aren’t as active in low temperatures. It should pick back up once things warm up, though, so I wouldn’t stress too much if the cold snap doesn’t last long. Just keep it moist and maybe cover it with a tarp or some straw to help hold in a bit of warmth if possible.

I agree with Christine. If it's frozen, you might have to extend the time.  I live in the PNW and I don't make biochar in the winter, because it's so wet, cold and dark.  I usually inoculate for a week. It has been freezing when I inoculated, but it has never been continually freezing for the whole time while I inoculated.  Usually, it's only freezing for 2-3 hours from 4-7 am, and above freezing for the rest of the day. I don't extend the time then.
