Although I always suffered root rot with DWC, even in winter, I still yield out ok.
I think DWC is suited to colder climates or you will be buying air con units and water chillers just to maintain temps.
I now have a drip system which can handle higher temps no probs. DWC just isnt good for my area.
root rot and High temps are not the fault of DWC it is the growers fault, and if you use plenty of airstones and something like sensizyme, hydroguard or any of the other products out there for "a happy res" you won't get root rot...if you get root rot in the winter when you are not battling high temps then "You" are doing something wrong,..sorry, peace
