Help! I bought these 4inch monkey tail cactus cuttings and potted them using cactus/succulent soil and my glazed ceramic pot does have a draining hole on the side.. only one remains green and firm. Three days ago I got a very inexpensive plant light because my house is chilly and does not get a lot of sun (there is a sunlight setting and a UV setting and it’s been mostly just on sunlight). Anything else I can do? I’m not sure if the others getting soft and wimpy is because they need more water as they get rooted or if they’ve received too much water? I feel like I have watered spaced out and small amounts at a time.
