It can definitely be done I ran dwc last summer it was just a little bit of extra work. When water gets that hot O2 deplets and nute uptake is slowed. I have found that during hot months I get better yields in Coco or pro-mix bc both inert and I can choose my feed according to plants telling me. I use A BIG fabric smart pots and I use different training methods, that's all great genetics under a great light and perfect environment day 48 since pistols@bignugz420 68°F is perfect but I used Botanicare HydroGuard in a summer DWC with res temps as high as 89°F and this is what I grew:

So really it can be done successfully.
