I completely agree! This is exactly what I wound up doing last night... kinda. I cut a small piece of the plastic lid out, and replaced it with screening from a screen top, but only an appropriate size piece to prevent TOO much humidity difference. I then suspended the lamp a few inches above the screening, and have it plugged into a thermostat. I'm gonna run like this for a few days and see what happens.
I'm new to BP's, so I'm still in that paranoid stage that I'm doing everything wrong, hah.
