Grow Lights For Dumb Cane?

Question

I recently bought a Dumb Cane plant and its leaves have been turning yellow. I’ve been scouring all the websites and youtube and trying to do what people tell me. I have been checking the soil every day, and I don’t water it until after the top two inches are dry. Heck, I bought a water meter, it’s just not here yet. I am misting the leaves and wiping them down to make sure it doesn’t get pests. One site said it might need more light so I was going to try a grow light. The lamp says it is full spectrum and has 3 lights that are adjustable. It also dims. My question(s). 1. Should I even use this? 2. What setting should I put it on? 20% 50% 100% or some where in between? 3. How far away from my plant should I put it? 4. How long should I leave it on for?

Answer 1

That will be unnecessary. They like ambient light, that it not direct. Too much light will cause yellowing, as will overwatering and underfeeding. They are heavy feeders.
