@BlaDe, would horizontal placement affect the number of seeds? My seed makers are horizontal and I’m averaging 2x the number of seeds returned almost exactly. For the Qi fruit challenge.
An average of 2x seeds returned is normal, that's what the RNG intends.
@BlaDe is referring to the fact that there's a specific pattern to when you'll get ancient seeds, which depends on the location of the seed maker and the time when you put the seed in (as well as the seed number of your file and probably a few other things). Since it has to be a specific time and location, it would be fairly hard to do it by accident, but I guess easier if the seed makers are lined up vertically.
If you're curious about this, you might want to play around with
Blade's predictor app. Set the app to seed maker mode, pick any location, and choose "Ancient Seeds" in the settings (as shown in the screenshot), then the picture below will list times on each tile. Those are the times when a seed put into a seed maker on that tile at that time will give ancient seeds. (You can also upload your save file (if you're on PC), or change all the settings on the left side to match your save file, then the results will be correct for your particular file.)
There's a bunch of other fun stuff in the predictor if you want to play around with it.
