First recorded grow.

Yes ,the most opinionated question on GD. How does each grower figure or count the age of their plants. I personally call day 1 when I see the first set of serrated leaves in between the cotyledon starting to emerge. Some start day 1 when the seeds break the surface of the soil. Others go by when the cotyledon open and drop the seed shell. So the official spread is about a difference of 3 to 4 days depending on the strain and temperature. It would be nice to have a uniform count that every one uses but don't forget your dealing with a bunch of stoners so that figures in to the equation. 😂
