@PinkyNotTheBrain i use an ardent FX too but i used to do it old fashioned way! 3hrs is plenty!
I never added water into my butter tho! Butter or oil + plant material (decarbed prior or after) and let it go! Make sure to stir it and u are golden! Pretty sure i did it at 240F tho not 170! 170 is for making tincture without going over alcohol vaporization point!
