Very low water, they get most of their moisture from morning dew, and a small amount of rainfall in the late summer.
We find that heavy misting every couple weeks is enough for most of the year, a little extra water down to the roots in August/September is best. To be fine with this level of water we recommend growing the Lithops in very bright indirect light, very little direct sun. With more sun they do take more water but it is tricky to get it right and they are rot prone if you try.
