I wouldn't say way above 65 but you can run dwc at 72+\- no problem as long as you stay away from benis and/or organics and use h2o2. Dwc isn't the greatest for organics anyhow but as long as you run a semi sterile res it can be done. It's obviously not ideal but it'll work without a chiller.
I am definitely going to switch to some kind of grow bags or something I can get a wider root zone rather than deeper buckets or pots.
