How much humidity does loose-leaf lettuce need?
What actually works
If your home does get very dry in winter (heating on constantly, static in the air), simply moving loose-leaf lettuce away from the radiator does more than any humidity gadget.
Why misting is not the answer
Buying humidity equipment loose-leaf lettuce does not need. Misting in particular raises humidity for only a few minutes, and repeatedly wetting the leaves invites fungal spotting — the effort is worse than doing nothing.
