Has anyone more informations about? - How does it work? - Is it similar to bod books? (5 seeds = 1 item count, each seed gets its own tray) - Does an identified seed stay identified after taking it out of the box? - How many different seeds can be put into? (The known picture of the box had 20 trays) - What are unique seeds? (Do they count 2 for 1 item count?) - What about stacking seeds?
