The universal advice for reservoir temps is to keep them in the 60s in order to maximize dissolved oxygen. I am running 2 airstones in each container and have no chiller. Temps are about the same as room temp - mid to high 70s.
It seems to me that bubbling this large amount of air around the roots would provide plenty of O2. Perhaps there would be other issues such as algae if the temps get up in the 80s, but so far the res is clear and clean and plants are healthy.
I would like to avoid the added expense and energy draw of a chiller if possible. Also, since the DWC setup does not recirculate, the whole plumbing arrangement would have to be changed in order to cool several containers from one chiller.
Anybody have any thoughts about this?
Thanks.
