It provides many benefits already, such as being a fulfilling activity as you said. It also cuts down on food waste since you can harvest when you eat it and leave it on the plant for a bit longer otherwise. It also reduces trips to the grocery store and reduces emissions of importing food over long distances. Finally, it's much cheaper if you grow from seed and upcycle plastic containers for planting. Especially if you grow expensive crops like fresh herbs.
