I agree with everybody else on playing the waiting game. It looks great so far!
I installed a T&G treated floor for my back porch, using a tool to really squeeze the wood together. If the humidity is low outside for a long period of time, the wood shrinks almost enough for the T&G to be apart (you almost can see the ground thru the joint). They are nailed thru the tongue
It was a choice of 1) put them together wet and hope they wouldn't shrink too much or 2) keep them banded together and let them dry for the summer. I let them dry for the summer and the outer ones warped so bad that some were unuseable and the inner ones were still pretty damp. Oh well, I just have to live with the result.
