Im currently running a 4" ventsTT inline fan off ebay with my 400w cooltube (5"), it has 187m3/hr max ,

my temps are 32c ,

would a 5" with 245 m3/hr lower them temps to 25-27c ish ?!

Or is it going to have to be the expensive 365 m3 hr ?!

Any help will be repped !

I have a 1mx1mx1.2m tent ,

Setup Inside Grow Tent - Carbon Filter>>>Cooltube>>>InlineFan>>>Out Of Tent
I am using a passive intake which is 1m of ducting from tent to a fresh air supply from open window.

i dont have much knowledge on this subject but couldnt you put another fan blowing down your ducting so that you have 1 pre and 1 post cooltube?? maybe your fan cant pull enough through your ducting cooltube and gilter. alot more resistance using filters..

Always vent more air then you have to in case you get stuck in a heat wave and you have to get your temps down. Also, a bigger fan on half speed will also run quieter then a smaller fan on full speed
