But I live in the pacific northwest, and there isn't much humidity here. Would the bottle be ok still?
I don't give mine humidity at all, its sits in a window in a room that is air conditioned (dry), and it still grows fine. After you ventricosa acclimates it'll be fine if you give it enough light. I'd get rid of the bottle as nepenthes like air circulation.
NO NO NO haha I bet michigan is not tropical
