ok, I'll put my 2 cents in.
I will give a cross # to pods that have seeds. No need to do every cross. Simply system here.
Example first pod to be opened with seeds gets #1, next pod gets 2 etc...
The next number will be the year 12,13,14, whatever the year is.
Then once there is a seedling to bloom, and I decided to keep it thru round 1 it will get a -1 or -2 etc.
From then on that number will stay with that seedling. Thru all rounds. Till it finds a name.
So the seedling number would look like the 40-12-7.
40=40th pod to have seeds
12=2012
-7= the 7th seedling to get kept
Now out of that cross I had maybe 10 in round 1.
After round 2 there are only 2 left, -1 & -7.
It works for me.
