"Do you have more pictures of your greenhouse(s) and herbs or are those on another forum? "
Tee, I'm sure I have oodles of pics on my computer. As topics come up I'll try to post relevant pics as needed.

Rosemary is a bit finicky in most winter households. The air is dry due to heat but yet at the same time it (rosemary) doesn't care for humidity for fear of getting mildews and mold. I don't grow it in the house (too dry) nor in my shoffice (wood heat, VERY dry) but if I did I'd only water it sparingly, soaking the pot it is in once, then let it completely dry out before watering it again. It should also not be placed near a heat vent, which would dry it out too much. As for sun, in a sunny window is fine but keep in mind too much of a sunny window may be too hot/drying so you'll need to check the soil as needed. Lastly, keep in mind, what may work for your winter growing may not work for someone in NC or Texas since the length of daylight will vary as well as the intensity of the sun. If it were me, I'd baby sit your fave rosemary, take it outside on nice days, even if only for a couple hours. (Fresh air revives us all, eh?)
Shoe (thinkin' he better pot up one of the rosemary plants and bring it in this winter, just for personal experience)
