You planted 4 basils because you deep down secretly plan to make OOODLES of pot-pesto to brighten up future long winters...
Cilantro may be difficult indoors; it seems to like quite bright light and fairly low humidity. High heat makes it bolt and go to seed, but coriander seed is wonderful in Indian and Middle Eastern food so no great loss.
Rosemary indoors is prone to powdery mildew; keep your humidity low and treat with SMC leaf wash regularly to prevent it... SMC= coriander oil, score! To propagate rosemary, most growers just take cuttings, EXACTLY as for pot, and somewhere in one of my posts there;s a shot of a clone dome that has a few pepper, lavender, and rosemary plants in with the cannabis lol!
Hell, I've traded pepper cuttings for pot cuttings before... pepper growers can be FREAKISH about their stock! lol
