Yeah I know it's a big ask isn't it. An 8 with a reducer might do it but wanna see if anyone knows a 6 that would do it. I reckon it'l probably take around 700 cfm and good pressure.
my first thought
Just to be clear do u mean one pushing and one pulling through the lights? i think that will just add more air pressure and keep the cfm at the total rated for one fan. This might be enough though I've got another 6" on my flower room intake il try it tonight. Thanks
This didn't work lol just a very noisy alternative to what I'm doing now. No noticeable temperature drop from the glass. If anything it might have been abit hotter, the two fans did not work harmoniously lol.
They weren't the same model. I don't even think they have a brand name, cheapy eBay centrifugal in line fans, one with a flat white casing and one with a bumpy grey casing. Both are rated around 350-400 cfm though. Maybe two identical fans would work better but I just can't see how airflow could be increased. I've got an 8" that I use to exhaust, I was gonna upgrade that anyways but in reality I ask more of my cooltube fan than I do of my exhaust fan. So might just buy an 8 or 10 inch hyper or iso or can fan and use a reducer. It's pretty essential that I do all my light cooling with one fan as its all one straight run and my lung room is about 20 ft away from my grow room and running a new duct to it would be an absolute nightmair, I'm talking at least a full days work just to run a duct propperly and hidden.
