Maybe dumb question. Anyway when I stacked and covered some fir it was about 18% moisture. Just checked it with the meter and it reads above 20%(22%-23%). If I mix it with about 1/3 12%-14% pine is it all good and safe for the stove(BK)?

I'm not familiar with fir, but I suspect it's heavier than pine.

If you take the average of the moisture contents, (2/3 @ 23 pct, 1/3 at 14 pct), you're exactly at 20 pct. But of the fir is heavier, I'd mix in more pine. It's borderline imo.

How did you measure?

Used a digital moisture meter. Inexpensive, maybe not real accurate, but I read somewhere that the cheapies were accurate within 1%.

Sure, otherwise you wouldn't have an actual number.

But how did you measure. Precisely. It matters a lot.

@stoveliker is wanting to know if you take a split from your pile and test it, or if you take a split from your pile, resplit that piece and let get to room temperature then test it. You’ll find a huge difference in moisture readouts. Just my input

No, not split, let get to temp, and then measure.
Get a split, let it be in a room for a day, then resplit and measure. If you reverse the order, you'll measure a number far lower than it actually is.
