How?
I cant find anything to get water from 15°C to 25°C to meet the requirements for Advanced tree farming.

Hey Andre

Presuming that you mean "Advanced Wood Farming", the requirement appears to be for water between 25 and 60 degress.

This being the case, you can use "Water Boilers" to increase water temperature to 50 degrees and the process should then work correctly.

I hope this helps.
