The plants are fun to take care of and a good thing to occupy myself with. My dad and I started growing watermelon and tomato plants in a little green carton from seeds. They grew extremely fast, with the first sprouts visible within two or three days. Eventually they grew too big for the carton, so my dad, my brother, and I moved them into small biodegradable pots. We had to cut some of the smaller plants out because they were growing in the same pot as others, but overall taking care of the plants has been a calming experience.
