Starting spring seeds indoors, How can I succeed?

If you used a good compost you should,t need to feed them until the shoots are a couple of inches tall then miracle grow will be fine, you don't need a grow light a window sill is fine, keep the cells covered with clear plastic these helps the seeds warm up quicker and holds in the humidity, until the shoots appear then take the clear plastic off .

Rotate the cell kit once the shoots appears so all sides get equal sun so the plants grow straight.
