Sara Williams This is part 3 in this series of pages. Providing the correct amount of light to seedlings is important. Cool white and warm White fluorescent tubes, used together, produce the best light for plant growth. Lights are easily attached from the ceiling or a stand using furnace chain and S-hooks. The S-hooks allow you to adjust the height of the fixtures upwards as the plants grow.
Seedlings require more intense light than more mature plants.
Insufficient light results in legginess, excessively large gaps between leaves, and pale stems and leaves. Plants usually require a certain 'photo-period' or time during which they have light. Any longer than this can be harmful. An automatic timer is a very worthwhile investment. Remember, most seeds require a fairly warm soil temperature in order to germinate.
