While there seems to be vastly different opinions and experience here, I've settled in on the assumption the humidity should be 40-60%.

To get there I added a small cool air humidifier to the cabinet and now have the temp at a comfortable 78 deg and the relative humidity around 48%. And I thought the kids were loving the MH lighting.. they're really perking up now. Pics once the Image Gallery returns..
