Fog will work to a degree. What the NASA boys have found out is you still need to make it hybrid. We tried just fog and failed because if the fog shuts down for even a hour the roots start to dry and damage. It over. We then went to hybrid fog DWC. Well the fog just helps getting them started and then the DWC takes over. To keep the fog going is useless. If you have a big apce between netpots and rez roots can dry out bad if fog quits and do damage.

If and only if you can make enough fog and keep it circulating very well will you have any success. Even then it will be limited. Goggle a search.
It looked like a way to use less nutes and water but it is very fragile.
