Hi, We moved and now there is only one North facing sliding door for sunlight and it has shade most of the day, I have brought “grow” lights to give extra light but Daphne, my Thanksgiving Cactus, has begun to get a few purple color leaves, so I change light spectrum & moved her so she get’s not so much light, I’m just at a loss w/all my plants b/c I don’t know how to get them the kind of light they need. I also re-potted her b/c her roots were coming through the root hole in first pot.
