Is a 24 on/off cycle the way they are supposed to be raised? I didn't know that if so. I bought a ghost plant off of Jay a couple months ago and currently have them under a grow light from about 8 am until 10 PM. Before I had them in the window but the leaves started drooping so I put them under the grow light. They look a lot better than they did when they were in the window just getting sunlight.
