I've been running fogponic grow trays far awhile now. My trays also use TAG or true aeroponic grow also. These aero/fog trays use two types of fog, either of which will grow from start to finish, I use both just for redunancy purposes. If either system farts, the other will carry the day till the problem is fixed.

When it comes to fog the biggest problem is "pond foggers", they can be sensitive to crude buildup, do not have much of an output and require more attention then a fogger designed for ag use. As Prodaytrader mentioned, a Frapaplas fogger (abt $629cdn) has enough output to run a decent size system, and avoids many of the problems. A major plus with the Frapa and even the pond foggers, they create a sterile fog that keeps the root zone clean of pathogens.

I have a picture album showing the construction of "fogfognugen" an aero/fog grow tray setup. :thumbsup:
