We simply add a small amount of crystal soil (aka soil moist) into the potting soil. In this case, the crystal soil is a soil additive for potted plants. Crystal soil functions as a water storage that retains moisture around the plant’s roots, constantly nourishes the plant with water.
I have asked other gardeners in different gardening forums, and it seems that the gardeners in the U.S. (and probably in other western countries as well) uses crystal soil only as a soil additive. Unlike what we have in Hong Kong, crystal soil is only in one color and shape – plain off-white, round beads.
While crystal soil is helpful in protecting plants from drought, there is a caveat, it seems. If the potting soil has been dried out to a certain point, the crystal soil beads in the container may actually compete with the roots and suck the remaining moisture out of the soil, making the situation even worse.
