Thanks. I'm going to try a simple system even though i'm doing a large volume. I've read the thread and seems like the rotary atomizer has some viability that's never been tested properly but i'm taking your advice and going slow with the rotary atomizer ideas. A little about me, 1. I have a large space. 2. I'm inexperienced in Hydro but grew many acres of actual tomatoes as a boy so i'm not new to plants and tend to be analytical and engineering oriented. 3. My people working for me are inexperienced. Since I'm looking at large space and using inexperienced help, i'm going to work with a first level system that's easier and less prone to problems even if not as efficient in growing. Your comments are really appreciated!! thank you.
