So question is do I go carbon filter cooltube inline then out of tent?

i'd put the fan on the filter, and have it exit through your tube, but to each his own.

Filter, fan, cooltube, exhaust

Always attach the filter to the input of the fan. That way you only have to worry about one joint being air-tight, the flange connecting the filter and fan. If you do it differently you run the real risk of venting the grow room smell out your ehaust.

I have been told you can cook the fans over time if your pulling air through them. Ive always gone Filter - fan - cooltube - exhaust

or another way I used to do it, was to have a completely different fan that's ducted from outside the tent, drawing cold air over the bulb and then duct it out the side and out of the grow room area.

For efficiency, its better to pull air, and never had a fan go out from exhausting lights. Did have to replace one that a rat chewed his way into, needless to say it was a lil off balance after that.

i had a shop owner tell me something once about fans. said, "think of it as a chain. you pull the chain, it follows, no problem. you push the chain, things are a bit different." i have a fan for my filter, and a diff. one for my hood.

I don't like this idea I had trouble keeping a 400w bulb cool with a wing setup bare bulb
Second I live in australia and the climate is hot there in no cool air to bring in unless I make it aircon
Electricity in aus is about 22 cents a kW

my buddy had a hot bedroom in his upstairs. we had the fan pulling air from the room to the outside. it stayed pretty hot up there. we turned the fan so the cool air blew in and it made a huge differance. this leads me to believe blowing air threw the hood rather than pulling it threw is the way to go.
