I don't have any special set ups for starting seeds inside. I don't use grow lights or heating pads. I do have windows on two sides of a room (south & west.) So there is lots of afternoon sun that comes in the room. I've had no problems with getting eggplant to germinate or with the seedlings growing.

Once transplanted outside I do have a terrible time with flea beetles. Fortunately they don't usually kill the plant, but will leave the leaves all pock marked.

Here is a link that might be useful: Growing eggplant

Thanks so much for the info and for the link!
