I took some leaves from two succulents that were getting too tall, I set them up Dec 15, but have yet to grow roots or any other signs other than calluses. For context: they have a grow light and I’m very frugal with giving them water, if I do water I use a water dropper to the soil, no misting. Am I just being impatient with these little plants or any tips on what I might be doing wrong? Thanks!
