Lighting aside, some plants are prone to issues when grown indoors. Hibiscus indoors are magnets to foliage mealy bugs, spider mites, and other plant pest. Strong lighting will help, but I still think they are more trouble than they are worth. If you are determined to keep a hibiscus, I would start with a minimum of 4 HO T5 bulbs over each and better 6 bulbs. LED spots burn foliage not at least 8”-10” beneath them, though floods could be useful, such as the outdoor security types. I am available to assist, but I second recommending a conversation with
@Venutus1 for particular product information and as source for bulbs and fixtures. He isn’t the only source, but he is a helpful, reputable, asset to the hobby and that’s the type of person I like to spend my money with.
