OK... I'm trying not to let the air temp swings bother me cuz the wiggler temps are much steadier. It was steady at 99.0, so I tried to bump it up to 99.5 (that's the ideal temp, right?) and it shot up to 100.4. SO bump it down a hair, temps back to 98.9. Bumop it up and goes back up to 100.7. Grrrrr.
.. what is a good range where I should just leave it?
Also, how do I get the hum stable? With nothing in there, hum hovers around 27-30%. I tried adding a warm damp sponge, and hum shot up to 75%! Any suggestions? please?
