I became aware of this sometime last week and have been doing research on it every day with surprisingly very little to show for it. Some people have mentioned a hearing issue in that the fogger can heat the nutrirnt water past a certain "cook" point but I have found several videos that show the fogger directly in the reservoir with the plants in an all in one unit, and then I find videos were the fogger is in a separate chamber but beyond that I can't find any solid info beyond how it works at a cursory level. So has anyone played with the system before? Is there indeed a nutrient water heating issue? How long can you have the fogger running? I know some fogger S are better than others and I'd want to use aluminum discs for the vibrating plates but The big thing I am looking for is the heating issue and how long I need to have the fogger running for optimal nutrient uptake.
