Hi Eric,
Sorry I've not been around and missed your question. With luck, you're already admiring your new, baby seedlings
Below is a screenshot of last year's sowing and germination notes (need to click on the image to actually read the text).
Come to think of it, the public view is here:
Hummingbird Mint (Agastache aurantiaca 'Fragrant Carpet') (Scroll nearly to the bottom of the page.)
FYI - Our "room temperature" in the winter and spring is 65-ish during the day and 55-ish at night.
Good wishes for your success!
Michelle
