All you need do is increase ventilation and use a smaller water dish. (But still keep it full of fresh water.) In a few days the cage should dry out enough that humidity becomes a non-issue.i have a new GBB and I'm asking for some tips about how can i keep low the humidity??
Im thinking in put some coal under the substrate!!
Depends on the size of the tank and the size of the spider.All you need do is increase ventilation and use a smaller water dish. (But still keep it full of fresh water.) In a few days the cage should dry out enough that humidity becomes a non-issue.
If the substrate remains damp, it may be too thick. A one inch (2.5 cm) thick layer or only slightly more is just fine. Much more than that is overkill.
Or, if you insist on allowing it to burrow in thick substrate, spread the substrate out on a piece of heavy cloth or canvass someplace in your home overnight or for a day or two until it dries out, then set the cage up again. Keeping the tarantula in a cottage cheese carton or deli cup for an evening will do it no harm. Consider it "camping out."
Beautiful tarantulas, and quite hardy if kept in a desert situation. Enjoy!
I presume this is leg span? If so, you're right at the tipping point. You should let the container dry out gradually over the next two or three molts. By the time it has a 2" (5 cm) leg span it should be in an effectively arid cage. No misting. No damp substrate, not even under the water dish.My gbb is at 1.5". Aren't I supposed to be keeping it at elevated humidity at this size?
