I've left this N. Sibusibuyanensis in here for over a months now and it seems to enjoy it. I don't push that thing at the top to close the gap. It stays nice and moist all day. Receives about 3 hours of direction morning sunlight. Our house stays especially cool even if it reaches 90 or 100 outside. I think it's the installation, tiles, and wooden floor. I don't know if this still works if room temperature exceeds a certain number.
