What kind of light conditions do seedlings generally require for optimal growth?

Seedlings generally require bright indirect light for optimal growth. This light condition allows seedlings to photosynthesize effectively without the stress that can be caused by direct sunlight, which can scorch tender leaves or dry out the soil too quickly. Bright indirect light mimics the natural conditions under which many plants thrive, providing the energy necessary for growth while maintaining a suitable temperature and moisture level for young, delicate plants.

Full shade conditions would not provide sufficient light for photosynthesis, leading to weak and leggy growth. Direct sunlight for 24 hours can be too intense, potentially damaging the seedlings and hindering their development. Lastly, no light at all would prevent the photosynthesis process entirely, resulting in stunted growth or death. Therefore, bright indirect light balances the needs for energy while protecting the seedlings, making it the ideal condition for their growth.
