Whenindoor-grown seedlings approach a suitable outdoor planting window
Start about two weeks before planting out. On a mild afternoon, put seedlings in sheltered shade for two hours, then bring them in before cooling. On later suitable days, add outdoor time and then morning sun. Set a return alarm each time.
- Progression
- Build toward the crop’s intended outdoor light. After stress, resume from the last tolerated exposure rather than pushing through.
