They're all pretty easy to take care of, but adults are more hardy. Once you have an enclosure set up, Hadrurus are probably the easiest to take care of, however setting up the tank with substrate deep enough and stable enough for burrowing can be time consuming.
Many people have trouble with young Hadrurus species because they require some degree of moisture in their burrows, and many people do not allow for that in captivity.
You won't have to worry about having the humidity too high though. I guarantee you that the humidity in your home is lower than it is outside, and with a infrared heat lamp it won't be a problem in the slightest.
