Why
6 hours clears the 6-hour bar, so mixed vegetables will produce — expect somewhat less harvest than a 8-hour spot would give.
- Flowering and fruiting are energy-expensive — below the full-sun threshold the plant grows leaves but skimps on harvest.
When this doesn't apply
- Count only hours of direct, unobstructed sun in the main growing season — morning and afternoon blocks add up. Dappled or reflected light doesn't count toward these thresholds.
