Hunting in the high 50s and 60s in the desert. Unless your breeding or incubating 65-70 is perfect. Humidity isn't necessary....just a water dish usually does the trick.
The temp my house gets to is like 69 to 72 at night and 74 to 77 in day. Are those good temps?Don't worry about attaining specific numbers. Supplemental heating such as heating pads are UNNECESSARY, room temperature will suffice. Forget about humidity as already stated above, it is just unnecessary stress. Raising a tarantula is way easier to raise than many think. The don't have as many requirements as a snake or even a dog for that matter.
For some unfathomable reason this thread just magically appeared in my e-mail inbox today...only about two months late. But I thought it interesting and important enough to respond for the sake of others with the same apparent misconceptions, searching for more information and help.
