Dwarf Sunflowers via Kratky?

So for Mother’s Day, I was thinking of growing some of these Dwarf Sunflowers for the women in my life to take home (I’m hosting a brunch for my Stepmom, Grandma & Step Grandma). I know they won’t be flowering by then, most likely, but I’m trying to figure out how to do this realistically.

I have grown them successfully in my Aerogarden Farm 12xL. This here is two plants, but I would obviously grow only one plant per kratky tub. I’m just trying to figure out if this is a good idea? How big a tub would I need if they only got about 2 ft tall? Should I also give them nutrients and instructions too?

Is this even worth doing? Haha. Should I just plant them in a pot with soil?
