A Gardener
working Jah garden
.Here's the way I think of it.
Frank germinated in water and it breaks the surface 3 days later
Bill used the paper towel method and his broke surface 4 days later
Chris placed his directly in soil and it broke surface 5 days later
The reason why knowing this would matter would be for comparative, Feed schedule or journal.
There is one thing that is the same for everyone.... when it breaks the surface.
So that should be day one in my opinion.
What about the moment they all started their various processes by taking a dry bean out of the pack? They share that also.... Or harvest, they share that too.
Alternatively, start at the beginning.
