Would my success in growing cannabis plants translate to nasturtiums?

In a cave once used as a stable and now abandoned, I found a wooden crate containing a dozen tiny clay flowerpots. They were of a simple design and looked old. I found two packets of seeds in a bric-à-brac drawer — sunflowers and nasturtiums — and I sowed them in the pots, which I arranged in a row on a shelf on the terrace.
