Hey sorry for the delay in answering. as to the pipe I like mine for the main reason it was free LOL. I get enough fog to fill my yard and the street too with one 1000 watt fogger. I use a second one in a hole at the end of the crypt (alongside the driveway) as an air cannon LOL I also use an old exercise trampoline (yes I do use it Mom) to keep the fog from rising at the end of the run.
Brad- Appreciate the details on your fog chiller setup. In lieu of building anything substantial insofar as a chiller, I think I'm going to try the drainage pipe chiller myself and see how it goes. One question for you: someone mentioned that a corrugated pipe may not flow fog as well as a straight pipe, unencumbered by the ridges. Have you tried/noticed any difference? Thanks!
