The fog system was made and studied by Nasa for space. It works great in the beginning when plants are small. If you were to run alot of very small plants you could get to harvest. Seems like the small micron's to make fog will not carry nutes to well. We to had to add areo to get good results. So it ended up being a mix. Areo on a timer and the fog was just enough to keep them wet but not keep the root ball too wet there are fogponics out there but 'm sure that the micron size was made bigger in the fog to carry more nutes. It's really good to start plants for a bigger system.
