I love upcycling these milk cartons into self-watering systems for my plants. The slow drip is assisted by the tiny hole you punch in the carton, and works long enough for me to go away for a weekend or quick holiday. You only need a few items to make this, and it definitely pays off. The nice, level squareness also helps it stay in place nicely in the soil, resistant to wind or pesky animals.
You will need a milk carton with a plastic twist-off lid.
