Here are some things I would like to know more about with regard to harvesting seeds. Seems like this would be an appropriate FAQ so I will make it a Wiki. Feel free to edit.
-When to harvest seeds:
Optimally when the plant says it is ready by dropping the seeds. If this is impractical, be sure the calyx is open. The seed should be visible, brown and mottled or striped. If it is green, yellow or white it is too soon and may not be viable.
If you are not concerned with bag appeal, it is also possible to wait until the weed is dried, cured and ready for consumption, break it apart over an upside down Frisbee™ and roll the seeds to the outer rim. Worked for this formerly 15 year old, brick-weed connoisseur.
-Methods for harvesting seeds
-Sorting, organizing, and storing
Separate the top quality (dark, large) from the mediocre.
I hear freezing is optimal. But only if there isn’t frequent thawing. Add a few grains of rice to absorb condensation.
-Documenting and collecting information for future projects and transfers
Landrace, IBL, Fx, Polyhybrid, herm tendency warning, etc:
