There’s an abundance of misinformation and guys not doing recirculating systems properly out there. If you use the right nutes, have the correct size res then when you go to dump the res there’s only a bit left in the res. I.e just enough to cover the pump on a feed cycle. I’d say that would be equal to or more likely be less than what you’d use in say a DTW coco with 20% run off. You’re still using same EC so the argument of using less nutes is null.Ive never done a recirculatory but from the Hydro section on here most agree that DTW uses less nutrients over a growing cycle than Recirculate. A little run off here and there vs the dumping of the tank every few days/week.
I get the odd power outage and im a lazy grower so nt for me- id love to give it a try one day but id have to be more motivated.
The best hydro systems for using less nutes and h2o IMO is DTW high pressure or air assist aeroponics. And 0 media / substrate
