This feature is part of Bonsai Genie.
I need to create a number of downloads for you so you can change your
Ideas Genie Pro 6 installation to run Bonsai Genie programs.
I haven't actually done this before so please be patient until I get a chance to do this.
RE: I have sown Poppies in trays and want them to pot out + place them in the garden afterwards: how can one register this with Ideas Genie Pro 6?
Answer: This could be done using the Events feature in the specimens screen GA100S23 which you mentioned.
