@Twinjax - I'm sorry you were badly misinformed. Peace Lilies use more water than most other common houseplants. Ideally, your Peace Lily should be watered just before or as it starts to wilt slightly. Although it will perk back up after wilting badly, wilting does cause leaf discoloration and the leaf stems gets a bit weaker each time.
@csandt - Moisture meters are highly variable from one potting ix to another. They may work well with certain potting mixes but not woith others.
