I can't really add anything here to the great feedback you've already received, other than exposing any split wood to really hot direct sunshine and breeze for a month or two, can get any softwood ready to burn very fast. Similarly, very
dry cold snaps in dead of winter can suck the moisture right out of wood in a week or two - freeze drying!
Moisture meter is good for anyone starting out, but after a while you'll know by look and feel whether or not it's dry enough to burn well. Anything under 20% moisture will burn ok with the help of some dry palettes - 15% moisture and lower and you're getting into the sweet spot. 12% in my area is tough to maintain as we get a fair bit of rain and very dry wood tends to absorb some moisture back in again once the Fall rains hit here.
I've scattered green splits on concrete in the full direct summer sun for a few weeks and that wood was ready to burn within a month. I've also put up wood in a confined shed with too little airflow and the wood took a full 2 years to season.
Rule # 1 - Check your chimney now, before you start your first fire. You never know how the previous owner took care of it and you sure don't want a chimney fire if he was lazy.
Nothing better than a brutal cold day and your wood stove warming your home. You win both when you stay in shape cutting, packing and stacking, and win again when you see no fuel bills. Brings a smile to my face every year
Grand Fir is a softwood with a modest BTU output, so it won't last as long as Douglas Fir like we have out here. The Firs tend to be pitchy so you need to keep a close eye on creosote buildup in your chimney. But you burn what you've got, wood snobs can freeze while they wait for the perfect wood so no worries - dry it, burn it and enjoy.
