Can fan, cool tube and carbon filter set up ?'s

I'm making my own cool cab. I just have a question I want to have (in this order) carbon can filter, 400MH cool tube and last a can fan to the outside. The guy at my local store said this wasn't s good idea, but couldn't tell me why. An idea why not or how to make it better?

I dont understand what you are saying? What's a bad idea...making the cab or the can filter.
The only thing I can think of is that maybe he thought that you were linking your can filter to your cool tube fan which probably didnt have enough power to cool and filter???

Sounds ok to me,in that order.Just make sure ya got enough fan to pull.

The guy at my local store is saying that he thinks running a carbon filter and the cool tube on the same fan is a bad idea.
I'm going about 50 CFM over what that filter is rated for so it should be powerful enough to get all the air it needs.

if you went filter--->cooltube---> fan ,then no thats too much distance no mater what the rating is, if you can do this
filter--->fan--->cooltube you would be good to go, in essence the hood will be cooled by scrubbed air

Another set back is the space I'm given to work with 24"x36"x72". I just put my grow setup on here (photos to follow)

Thanks

you may want to think about desinging your own diy can filter to fit the space needed. Thats what im doing

I was looking into that as well I really need it to work well and I'm not sure how well the DIY type will work.

Go to the DIY section and look for Wolfman Zen's DIY walmart carbon filter. This is what i was going to try except on a larger scale

I remember seeing pics of that somewhere[or one just like it], it looks easy to put together, and suprisingly cheap and of good quality.

I just ordered a carbon filter that has the fan attached. It's like a can fan, but its all one piece, not screwed together. So it cuts down on noises and has a fill hole in the other end for when you need to replace the carbon.

What he said..

yeah that's what I'm planing on doing, I might even add another fan on the other side of the cool tube.
so the setup would be: Filter, fan, cool tube, fan

I did this DIY scrubber:

with this DIY fan/mod
Stanley Blower Fan Mod [250cfm+ for under $50]

sucks through filter blows into light, inline can fan on other side of light to help

budget for first grow

Hi...

I know this thread's been neglected for a couple months but I thought I'd share my experience with setting up my 2' x 4' x 8' closet for flowering. I have a 1000w Quantum dimmable ballast firing a SolarMax Dual Arc bulb inside of a cool tube reflector. I also have a six tube T5 fixture with four grow and two bloom lamps mounted to the back wall and a dual T12 fluoro fixture loaded with two Philips UVB med bulbs. The only real heat maker is the HID although the others do add a slight amount of additional heat to the closet.

My 40 lb. can filter is mounted upside down in my closet with the opening facing down. Due to noise security considerations I needed to put my fan up in the attic. I connected my filter to my cool tube reflector with a short piece of semi rigid duct making a gentle elbow to make the angle. Having to re-route the air flow up and into the attic I attached an 6" elbow to the other side of my reflector and a section of semi rigid duct up and through the ceiling and connected it to my Ostberg 630cfm inline fan. To help with the noise I took the large box my 40 lb. filter came in, glued sound absorption 3" foam to cover the inner surfaces of the box, cut a 6" hole in the bottom of the box to route the duct through and I placed the fan inside the box and I keep a flap open on the top of the box for air to escape. It reduced the noise by around half. To eliminate any vibrations coming through the ceiling I used rubber straps hung from attic rafters to elevate the box 6" and prevent any coupling with 2 x 4's in the attic...

Having said all that... Whew! I'm amazed at the power of this fan. There is plenty of pull to keep the temps in the closet only a few degrees warmer than the ambient temps in the house. It stays between 74 and 77... perfection! I just wanted to share this in case someone else is in the same situation... You can run things this way as long as your fan is powerful enough to handle the pull and the Ostberg I've got kicks ass... I can run my Quantum ballast at 1000w without any heat problems.

Happy Growing!
