I heard it's between 65 and 70 maybe 72 for optimum growth, then again I heard 65 is too cool and that 68- 72 is the best. Roots love cool water not ice water is what I'm getting. I'm still a rookie so I have no idea lolI have never heard of anyone pushing for warmer in DWC , colder water holds more oxygen so id assume your goal is to go as low as you can without harm
