Modding Help How to make custom farmable plants?

I've been working on a little mod that adds more farmable plants in-game, but I can't seem to figure out some of the tags in the related seed.object file :/ mainly the "stages", "orientation/spaces", and "maxImmersion". Anyone have any tips?

 

This is from automato

Code:

 "stages" : [
    {
      "duration" : [280, 320]
    },
    {
      "duration" : [280, 320]
    },
    {
      "alts" : 5,
      "duration" : [1170, 1230]
    },
    {
      "alts" : 5,
      "harvestPool" : "automatoHarvest",
      "resetToStage" : 2
    }
  ],

So (assuming I am right) , this plant has 4 stages. The first stage last 280-320 (i assume seconds).
If you look at the png file, the very first graphic is the first stage, the image that shows when you put it down.
the second stage is the second graphic, this stage last 280-320
The third stage is the next 5 graphics, this is what the "alts" means -- If you look at the frames file, you see this...

Code:

"default.2.0", "default.2.1", "default.2.2", "default.2.3", "default.2.4"

those are the names for each of this stages "alt" appearences
the last stage also has 5 "alts" , then it has the harvest pool for when you "use" it and it tells you which stage to reset to after harvest.

I'm not sure what max immersion is, the orientations is just the graphics used for the plant and sets it to use tilled soil
