What temp do i keep my grow room at when using DWC

Also should i use computer fans or window fans ?

mid 70's... use whatever fans you need to keep things under control

yes mid 70, and a lower water temp is key!

Thank you very much, i will make sure to keep both at good temps what would you say for the water temp.

never go over 70 with the water temps... mid 60's is good

How about high 50's and low 60's with a possible drop into the 40's during the night?
