What is the recommended humidity level in a home with hardwood floor? What moisture reading is normal for a sample taken from a probe in the wood for moisture? Wood is 3/4" solid Hickory unfinished. Thanks!

I'm sorry, but you just don't sound like a flooring contractor to me.
I would be asking you those questions if I was interested in having a floor installed.

B.D.R. - I should be more clear in my question. We have humidity in the mid 40's, and moisture at about 6% in a hickory floor. These seem like great conditions. Floor acclimated for about 3 weeks in air conditioning this summer. We have noticed that boards have either shrunk on the groove side, or were slightly mis-milled. Has anyone experienced anything like this? Thanks!

If your using a meter with the metal prongs then your only measuring the moisture on the surface of the material. You need to use a meter like the Wagner mmc220. That's the only accurate way to figure out what the materials moister content really is. I don't see humidity levels like that in these areas as we are in the mud 35's here normally in a conditioned space. If your material has shrunk it sounds like it was not low enough moisture when it was installed.

wood comfort level is the same as a humans..

35=45% ideal and what any mill or manufacturer wants.

6% would be ok determined by your location..

considering the hardness of Hickory..this sounds good.

the shrinkage...considering it Hickory makes sense.

Hickory runs wild..how wide are the boards?

do a google search..you will find tons of issues regarding Hickory floors..the next will be Maple..and then Brazilian cherry.

these materials constantly experience issues with rapid moisture changes
