Fabulous!
I am glad you are starting this. I have 700+ grown outdoors year-round in containers and a weather station a few yards away. For 2023 I have not recorded the separation between breba start dates and main crop start dates so I might not be of help until next year. In fact, I’m already planning on it.
Just as a heads up, Harvey C. has 355+ specimens which he’s possibly collected data for. Between the two of us we only have 33 in common! Also, I am working on a vetted list of variety names sold on figbid since 1/1/2020. This will be published here.
