What are some things you can do to make lettuce turn brown?

1. Keeping lettuce out of the refrigerator can speed up the natural process of lettuce wilting and turning brown. 
2. Excessive watering can also speed up the natural wilting and browning process of lettuce. 
3. Lettuce exposed to direct sunlight can quickly turn brown as well due to sun damage. 
4. Allowing lettuce to dry out can also cause it to brown faster. 
5. Older leaves at the base of the lettuce will rot faster and start to brown if they are not regularly trimmed off.
