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. It was my first attempt at growing anything since 1979, when I raised six cannabis plants in my father’s greenhouse with such spectacular success that I had to permanently leave the roof panes open to accommodate them.

Rarely have sunflower and nasturtium seeds commanded such loving and indefatigable attention from the sower. When the little green sunflower shoots appeared wearing the split-open pod husks like little hats, I danced before them like David before the Lord. On sunny days I moved the seedlings from the shelf to the full sunlight of the outside table.
