Hmmm... not sure how to describe the level of wetness. You'll notice that I use crystal clear cups. The primary reason is, I want to see the root development. The other advantage is I can judge the dampness. There are no drain holes in my cups, so I want the sand to be fairly moist but not to the degree that I see water collecting in the bottom. I pour up to an inch of water in the tote that I place the cups in. This creates a very humid environment that not only protects the cutting from water loss, but also helps keep the sand from drying. I will probably not ever have to add any more water directly to the cups while they are rooting.
