I have researched this inquiry but I cannot seem to find valid information relating to the first week of a seeds life once germinated. This is the stage where it is in darkness and not suppose to receive any light. (Before it is a seedling, before it has any leaves) Assuming the stem has just emerged and rapidly started growing 2 inches and the cotyledon is still closed. When will the leaves deploy and signal that it is ready for light? Assuming you use soil / peat / other type earth based starters, would the seed ever need to be watered again during this time other than the initial soaking of the medium in preparation for sowing.
