Message: <blockquote data-quote="Tomoran" data-source="post: 81997" data-attributes="member: 1152">Personally, I would get rid of the hygrometer, or in the very least, only use it to give you a ballpark figure as to if the humidity is low or high.Which species are you trying to keep exact humidity for?You definitely shouldn't worry about humidity; the "ideal" humidity ranges offered in care sheets are useless, as humidity fluctuates in many of these animals' natural habitats. For example, the humidity where I live was 100% two days ago, and it's about 40% today. There is no correct or precise humidity requirement for these guys. Some also have rainy seasons and dry seasons, so pinning down the perfect humidity level is fruitless. This is probably the one thing I wish I had learned earlier in the hobby.I honestly feel that many folks put their spiders at risk by trying to attain the "perfect" humidity levels. Take the A. versicolor, for example. For years, keepers were told that they required high humidity, which often lead to constant spraying, wet sub, and overly-moist enclosures with inadequate ventilation. I've had mine for close to three years now, and she's done great on dry substrate and a water dish (and this is during the winter when humidity in my home plummets due to the furnace running). The general consensus now is that these guys can be kept with good ventilation and water dishes.If you're afraid the air is too dry, I would suggest putting in a larger water dish. It's a safe and natural way to raise the moisture level a bit. If it's a moisture-dependent species (like a T. stirmi or O. violaceopes), then keep part of the substrate moist and provide large water dishes. However, don't worry about trying to keep precise levels of moisture in the enclosure; it'll lead to more harm than good. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" /></blockquote>
