My home is sided with Hardiplank siding. I was wondering if there would be any issues or problems if i caulked the gaps on the bottom of each "course" of siding/planking?

thanks in advance

You should not caulk the courses. You might trap water there and you'll will end up with a problem. You could caulk the sill plate, around windows, doors and through the wall air conditioners, but not the courses.

thanks for your quick reply
