First Signs of Growth:
Once your seedlings begin poking through the soil, they will start to straighten up and unfurl. What look like two leaves will appear. These are actually leaf-like structures, called cotyledons
, that are part of the seed and serve as food sources until true leaves are formed and the plant is capable of photosynthesis. At this point you should move your seedlings under a light source.
Move into the Light: Your seedlings will need between 12-18 hours of light each day. This may seem extreme, but artificial light and even the low rays of the winter sun are not as intense as full summer sun. The best way to insure regular long doses of light is to attach your florescent or high intensity plant lights to an automatic timer.
