Hello I just bought your  farming template, it's very good. But I have some questions.

1. How does crops grown?  I mean I checked code and I don't know how "Variable <self>Growth " in the carrot working.
There is no  "<self>Growth +1" when day skip or something like that to change  stage of carrot .   
How  "<self>Growth " got+1  every time skip?

2. What is "<Self> Calculations" ?   
   I see them turn on every time when carrot is watered.  and no turning off.

3.How do I make a carrot that need 10 days to grown? 

Thank you very much.
