Initial setup was eggs on grate on hatchrite with press n' seal. However it seems my hatchrite was a bit dry, so I had a few start to dimple. I added distilled water to get the humidity back up, and thought I would put the accurite inside the tub so I could read the humidity (been checking temps w. IR gun) but they seem to last 4-ish days before they die. Am I just incredibly unlucky with thermometers? Or is there a better device I can use to measure humidity inside the tub? Thanks!
