I would keep them in the high humidity environment. In my two tries with seeds I got them to the point where they had started to grow their main leaves, but after that I eventually all lost them. I never quite figured out if it was due to too wet or too dry. I suspect the latter, but am not sure.
Not sure if you were on the thread where we posted a number of links to websites with good information a while back. I forget what the thread was and do not have the links handy, but there are suggestions out there.
Keep yours in the high humidity time you see 4 leaves - the two that will eventually die off and the 2 that will become the plants only two leaves ever.
