Free food

Free food is a hard one since you have to take care of plants for them to grow right.

Ask someone a trick question sometime. "Where does food come from?" If they answer, "from farms and the earth and gardens" say "What, No food comes from the stoooore, jease it's a simple question." and answer the opposite way if they answer the opposite.

If you had a hydroponics garden in a green house you wouldn't have to worry about weeds or cold or bugs or animals or most disease. So a lot less work to do and bigger harvests.

Indoor pots may work just as good though.

Have a covered open air eating area next to the greenhouse for eating fresh food with no fridge.
