I have these orchids that I bought three years ago, and they are not flowering. At the beginning they almost died because of insufficient light in my home. I moved them next to an always-on artificial source of light and they came back to life. Even a couple of new leaves appeared but they have never produced flowers. What can I do to make them make flowers?
They are is a kitchen, no natural light. However the natural light in winter conditions is worse than what they have in the kitchen. The pots are on the top of my fridge.
