I'm not sure. What is that connection? 6"?

Check out my carbon filter DIY Thread in my sig. Bump it for me!
Works with my In-Line Booster Fan, 6".


Whoa, dude you paid 85$ for that? Did you know for $10 more you could have gotten the 180cfm and for $5 more than that you could have gotten the 265cfm and for $112 they sell their $465?

I think their price ranges are ridiculous, but keep that in mind incase you decide to buy another one.

No it's a corner of basement, just going to buy some tee's and split the fans, so i can run just the 95cfm as outake and the eco-plus for the intake for both rooms, what you think???

I thought you multiply the dim's and then divide by 5 and that should be the # you need to buy or higher, i came up w/84, the fan does 95,is this correct???

You could try to make it work for now if you have a small number of plants but how many lights are you going to hang exactly?

I was just trying to use two fans instead of 4, see i split the area in half, one side for veg and one for bud, i got bathroom fans in the veg, which are too loud because they are made to be in the walls, so i wanted to buy some tee's and just split the fans in the bud room (the 95 cfm for outtake and the eco-plus 4in. For the intake, to vent the whole room 10 x 6 x 7, what you think??? Got about 25 seedlings and 3 mothers in the veg and just cut the buds down inthe other room...

What kinda lite system are you gonna use, 400, 600, 1000 watt or CFL? Just to give you an idea of what your gonna need if running MH/HPS. My grow room is in a 3X3x8 closet and that's 72 sq ft, using a 400 watt lamp. I started out with two 60 CFM blowers venting into my attic with a non cooled hood and that didn't turn out so good, temps in the high 90's

Since then I bought a 6" cool tube and a 530 CFM inline exhaust and I use that with the two 60 CFM blowers for a total of 650 CFM. I'm pulling 9 times my rooms SQ footage every minute and my room temps went from high 90's down to mid to high 70's

Now your room is 10X6X7 for a total of 420 square feet. So in my opinion a 95 CFM blower is not gonna cut it. Although since my room is not quite as big as yours, you should be able to get away with something like a 500 CFM inline fan.

Well I hope I helped you out some.

Peace.

Is a 95cfm activeair blower can handle a 10 x 6 x 7 grow room???
in short, no, you have about 420 cubic feet of space to ventilate. You want to exchange all the air in the room at least once per minute. Cubic feet = Width X Height X Length
10 X 6= 60 and 60 X 7 =420. You want a fan that pushes about 400+ CFM.

So do divide anything, cuz dude in the hygro store told me to do the same formula but multiply by 5 and that is the amont of time you want to ventilate, so every 5 min...he told me a 95 cfm should be fine, waht you think??

Well since your not using MH/HPS your not gonna be dealing with a lot of heat issues. So you might be able to get away with that. Also if your using Co2, did you know that you don't want to exhaust your room while lights are on because you'll be defeating the purpose of even using it.
