dwc is less forgiving, if the res temps get to high the plant is fucked. hydroton with a top feed recirculating back to the res is idiot proof. if you forget to chill the res your still fine. I recommend synthetic nutes also, they dont rot and pollute the res with contagions or bacteria. Ive tried DWC and it was more demanding. individual buckets filled with hydroton and a drain back to the res with a top filling system is the easiest i have found so far and far more forgiving than dwc. It's easier than soil for me.
