A cutting requires roots to uptake water, we must create an environment so humid the plant can absorb moisture through its one set of leaves, 70+RH% but also a good supply of fresh air and full temperature control. Once I see light lime green it will signify new growth of the plant, I will know it has started to re-root.
@Ultraviolet, thank you! It’s scares me so I put it on a Wi-Fi enabled switch with a timer countdown. I like the colors they yield toward the end of flower.
