FAQ About Indoor Plant Seed Germination Techniques
How much light do seeds need for successful germination indoors?
Seeds generally require indirect light or darkness to germinate, depending on the type. Some seeds, like lettuce and certain flowers, require light to germinate, while others, like most vegetable seeds, need to be in the dark. Once germination begins and seedlings appear, provide 12-16 hours of light daily using fluorescent or LED grow lights to support growth and prevent spindly seedlings.
