Hello Minnie72, if you have a heating mat, that may help add additional heat below as you root your plumie. I only water at the very first time I planted the cutting, and then I don't water my Plumie till there is at least one visible fully opened leaf. Leaf claws does not count yet till it actually opens up. We get poor humidity levels here so it also affects its wake up time.
I position my plant in part shade here, since we easily get too hot and dry and the plant is not ready to get watered till it awakens. Once it is in that spot, I don't move it anymore, got to let it get used to it, and wait patiently for them to wake up. Some cultivars really take awhile to awaken, so it needs a good deal of patience. I also use cacti mix but I add a lot of pumice or you can also use perlite in the media to make it very well draining.
