Yup...resurrected thread. But I will throw my 2 cents in.
I have some grow bulbs along with my UVB, but it was not enough to keep mine from withering away or loose all but the top leaves because the light is just from above. And with the Electric bill skyrocketing, I am too cheap to add any more bulbs, just to keep $10 plants alive.
My solution was to have 6 hibiscus plants that I use in rotation. I rotate them out every week to get some nice sunshine and it seems to work for me. I have done it this way for over a year and a half and they are still growing nicely. Plus I have some smaller plants from some cuttings I have started a few months back.
Every now and then I get an Aphid attack, but a quick spray with soap, Veggie oil and alcohol and some extra time outside keeps them at bay.
