It’s the moisture content that causes problems. Wood will usually stabilise in whatever environment you store it but if you move it from a damp garage to a hot centrally heated house or vice versa then you may get warping. It’s best if you can keep it somewhere in between, somewhere dry but which isn’t too hot.
It will acclimatise if given time but going from one extreme to the other is usually what causes the problems. My workshop is in the garage whch is attached to the side of the house and gets sufficient warmth to keep it dry although it does get cold. in there. Like Neil I don’t have any problems normally as everything is kept dry.
