- Pre-sprouting in the frig – For most crops, 0.2 inch (5 mm) [initial root] is enough. For lettuce half that length is good, and one day may be time enough. per Pam Dawling.
- Lettuce can be planted during late summer or early fall while the days are still hot provided that the seeds are germinated in the refrigerator for 4-6 days. Per SESE.
