What affects lettuce weight
- Type. Iceberg is dense and heavy, while butterhead and leaf lettuce are lighter.
- Size. Larger heads weigh noticeably more than small ones.
- Water content. Fresh, crisp lettuce holds more water and weighs more.
- Trimming. Removing the core and outer leaves lowers usable weight.
- Growing conditions. Well-watered lettuce forms heavier, fuller heads.
