2 tents, 1 exhaust

[eternaldreemer]

Hello everyone! Hope everyone had a great New Year's holiday.

I'm attempting to connect 2 tents together with one exhaust system. Now, obviously there are at least two ways one could go about doing this. The first way is to use a wye from the exhaust fan to connect one duct per tent. The second way would be to connect both tents together with flex duct. I have read of both ways, but I feel that the second way would be best for me. Any suggestions?

Oh, by the way, I have two air cooled hoods. My veg tent (2'x4'x5') will hold the 600w MH lamp. My bloom tent (39"x39"x79") will contain a 1000w HPS. My exhaust system is made up of my exhaust fan (451cfm) and one long carbon filter with 6" port. I also have a spare inline booster fan (240cfm) that I plan to use. The closet in which I'm storing my tents is approximately 4'x9'.

Which would be the best way to run my exhaust?

One word: plenum

Two words smoke alarm

Confused. A plenum is an air box.

I thing it would be better to get a second fan.....Just a thought...

[South Sierra Dude]

That was my solution.

rough picture...sorry

[South Sierra Dude]

Air tight box = plenum.

[Green75]

Yes.......

Wouldn't you need a much stronger fan? I guess it depends on the temp. U keep it at.

[South Sierra Dude]

This would work.

[dontknownuttin]

Something like a manifold huh?

[South Sierra Dude]

Pretty much. Put a fan6on one hole and exhaust on the other two

[Green75]

The fan needs to be hooked up to the filter....filter pulls from box which is getting fed by the tents exhaust

Saw this at the San Diego area nuke plant I do not know if it will fit in your grow room.

You guy's are killing me....HaHa.....

Wow, those are all pretty good ideas. Thanks for all the input.

Initially, this is what I was thinking about doing (I'm no artist, sorry). My setup is inside the closet of a spare bedroom. The idea was to place the carbon filter in the flowering tent to keep the temperature cooler than the veg tent. I couldnt really come up with any other way, and I've never seen done the way described above. Not a lot of room in my closet after having to put 2 tents in there, but I suppose putting a box like that could work in there.

So where exactly should I place my booster fan if I did it that way? Or would my 450cfm fan be sufficient enough to do it all?

Greens drawing is parallel yours is serial. Just curious why the complicated set up?

[eternaldreemer]

I have just always wanted my own perpetual grow space. But I live in a mobile home with a sheet metal roof in the deep south, so temperature control is a real issue for me, especially during the summer. And since I'm only renting the place, it has to be as clandestine as possible. I just want to be able to ventilate my tents without having to buy anything else or make any other modifications to a home that isn't mine.
