What type of light do seedlings require for optimal growth?

Seedlings require bright, indirect light for optimal growth because this type of lighting mimics the natural light conditions found in their native environments. Bright light supports vigorous growth and strong stems, helping to prevent seedlings from becoming leggy or weak. Indirect light ensures that the seedlings receive sufficient brightness without the risk of excessive heat or leaf scorch, which can occur with direct sunlight exposure.

While artificial fluorescent light can also be beneficial in certain situations, it is typically used as a substitute for natural light rather than being classified as optimal for all seedling needs. Low, direct light might not provide the intensity needed for healthy growth, and dim, filtered light would not supply enough energy for the seedlings to thrive effectively. Therefore, bright, indirect light is pivotal in striking the right balance for their growth requirements.
