Wood and Controlled Climate

[Pieter Gaskin]

I know many luthiers store their wood in a very controlled climate in order to stabalize the wood before building.Is this done mainly to give the builder a solid reference point to start?
It seems to me that in real world conditions an instrument can do some "strange" things once it leaves that controlled environment.Would building in a less controlled environment expose some of these problems earlier?
I have a nice piece of tiger maple I was going to use for a top.It was from kiln dried stock. I then split it for a bookmatch.One month later,one piece had warped and twisted enough to be firewood where the other one is bone straight .Again "uncontrolled" conditions(a room in my house) where the temp and humidity changed due to furnace operation and winter humidity levels.
Thanks
