I find that after suriving the initial shock of being placed indoors, auto misters (humidity) along with lights (warmth) go a long ways. You won't get alot of blooms indoors, but I get alot of green leaves on my hibiscus used. I like using this plant for smaller chameleon species.
I get much flowers to, he come all the time Just dont water the hibiscus when the soil is wet, wait til it gets dry then water it. you can still mist the flowers and the leaves but dont water the soil before it gets completley dry!
