The cuttings I've taken from these plants aren't true hoya babies because cuttings are actually a clone from the mother plant. That is, they are the same age as the mother, albeit smaller.
These tiny ice crystals will grow as water vapor molecules go directly from the air to hook onto the ice. Once ice starts forming in a cloud, the water droplets will begin evaporating while the ice crystals grow. Now you can see why the water doesn't become a big clump of ice. As soon as a water droplet or ice crystal grows large enough it begins falling. It isn't able to hang around in the cloud and grow any larger.
