hey guys n gals. my little grow room is sealed all bar where my "in" and my "out" fans are. i have ducting that does a right angled bend outside of the grow room (to stop light leaks) and i was wondering if i placed a fly/bug screen and put it over the end of the ducting, would this drastically reduce my air flow?
the fans are only very basic inline fans. 65W each 250mm diameter. they don't move an enormous about of air so i keep them running pretty much constantly.

As long as air can get through the screen easily enough you'll be fine.

yeah that's what i was asking. how much would a pretty fine screen *such as one to block bugs* hinder my flow?

Shouldnt have to much of a influence. You can test it if you want.

Do this. Take a lit candle and hold it infront of your air inlet and take note of how much the flame is moving.

Then install your bug screen and do the same thing. Then compare. You'll see easily enough if it has a big impact on your air flow.
