eBay sells foggers...

I guess that the setup would be similar to a DWC or something...

Maybe a big Rubbermaid / Sterilite tub... air stones in there... and your fogger(s). Also, I guess a fan would be good to move around the nuted-up fog.

But... the fog would get everywhere... so the fan would have to be very good... very good, not as in 1,000,000 CFMs... but, sealed, 'explosion proof', and, well, I guess you can expect lots of rusting.

But sounds good! Please keep us update... this is very interesting.
