Hi Batboy
I understand your concern for the blower/filter combo. This was also my concern, the fan blowing too much air through the filter and it not working.
As I stated earlier, that inductor fan that I was using ( here is a picture of it: http://img163.imageshack.us/img163/2752/inductorfan.jpg ) was doing nothing. IDK how some people get away with using PC fans with this thing. The inductor fan was rated at 80CFM. With the filter hooked up it moved nothing. Nothing at all. I have a small garden thermometer in there. Temps were in the mid 90s. Not good.
I am using a 4"x20' dryer hose to hook up the blower and filter. I don't use all 20' of it of course, so alot of it is still coiled up. It does have a fair few bends and twists, a few drops and rises along the way. All those will diminish your CFMs.
I did a test run with it yesterday with the filter on and it seemed to blow a moderate amount of air, not alot but a nice steady breeze. The filter seemed to suck enough air to properly remove excess heat while not too much as to prevent efficient air scrubbing. Of course, only time will tell how well it works.
With the blower running and the filter in place, there is indeed a negative pressure in the tent and the air flows inward from the flaps, never out.
My tent is tiny, only good enough for autos or maybe 12/12 from seed, or clones, which I have no access to. The entire thing measures 1'4" x 1'4" x3'11"
The "Hydro" setup is nothing more than a 6" pot filled with a 2:1 ratio of rockwool grocube to perlite. Nothing fancy.
Peace
