Depending on how long you waited before adding the fan.....Drying too fast causes cell collapse, lots of defects and frustration. Sounds like you have method that works for you. Any snow yet? We had flurries last week in the middle of a rain storm. Thought it was odd, but have seen it plenty of times, just not in October.I've not had that problem with the heated floor. It's pretty hard on the bottom layer or two, they tend to warp and crack more. I deal with that by making sure that the bottom boards are low quality to begin with. I think if I enclosed the stack and added a fan it would really speed things up if I was in a rush.
