Convection ventilation is an interesting comcept. An ultasonic fogger cascading from top to bottom will also help with ventilation I think. These are a new gadgets that are quiet, simple, and easily purchaed on the internet ($25.00). Then you get cooling, humidity, and ventilation. I might get a fogger come summer when I expect to have overheating problems.

I used a fogger as a cascade and almost immediately had problems with botrytus mold. It grew at a phenominal rate and I lost a lot of plants as a result.

Probably best not to use that all day.

I've never heard of anyone running their fogger all day! Best to put it on a timer, and figure out how often you need to run it, which is probably only once a day, for a brief period.

I tried the poison-frogs link, and it worked for me. Try it again, I've put it below.

I've got both my foggers on humidistats- That way I can set the humidity I want and walk away.

The lights are on timers & fans are on a temperature circuit. Gets to hot fans spin up.. They turn off when the temp lowers below a set point.
