fertilityFactorGrowthRate

[generalcrusher]

So I have one question. What is the fertility factor growth rate modifier for? (in the plants_cultivated.xml)
I understand what growth per 20k ticks is, but I dont know exactly what this does. Thanks in advance.

fertilityFactorGrowthRate determines how much the plant is dependant on the soil fertility.
A value of 1 means its growth is 100% dependant on the soil fertility.
A value of 0 means it will growth at the same speed whatever the soil fertility it is planted on.

I have one more question.
Is there any way to configure what the plants grow on? So for example, is there a way to make a modded plant that grows on sand instead of soil?

[Rikiki]

Plants can grow where the soil fertility matches the <fertilityMin> requirement.
So PlantAgave will grow on soil with fertility >= 0.3, PlantSaguaroCactus with fertility >= 0.05, etc...

I believe you cannot specify that a plant can only grow on specific cell type without dll coding.

Be aware though that the growing zones can only be placed on soil with fertility >= potato.fertilityMin. This is hardcoded (not modifiable in XML).
