Relatively high(Minnesota) but I use a dehumidifier. BTW, I was reading online and I learned English shipbuilders would submerge timber for up to ten years to acclimate it before work and that it took 40 acres of oak for one first rate vessel.Just a note: even when I build furniture, I move the wood to my shop a month or more ahead of time to allow it to acclimate. I prefer kiln-dried woods vs air-dried. Wood moves. In the little lumber in models, movement affecting the model itself is minimal though. Do you live in a high humidity area?
