Not sure if you answered this or how far you are into your grow, but how dank does the cheese smell in flowering? I ordered some cheese x nyc diesel seeds and I want to know what to expect.

The cheese is awesome, actually my AK47 overpowers it (smellwise) the cheese smells like cheese.. especially when drying.

Another option would be to use a centrifugal fan and split that to your lights. Use it in combo with a variable speen fan control to turn back the flow to 50% (this reduces noise IMMENSELY and, using a more powerful fan, you still get better flowthrough.) After all, these type of fans are maximized for this application (meaning they retain their CFM's to a greater degree in a sealed environment).

This one fan would be enough for all of your lights.

I use this one to cool 2 1000w HPS.. I have to use a duct reducer(8"->6"). With the fan on Low (25-35%) the cooltubes are warm to the touch (but can be touched) and can't even hear the fan. Plus, I can still crank that bitch up to Full once summer comes :)

With that being said.. Those duct fans would probably work fine. Guess it kind of depends on the length of ducting... their description recommends a blower for longer runs, which is what I was recommending hehe. Don't use an exhaust blower with ducting though--they aren't designed for that and will lose most of their performance.

I would run a single 440 CFM. Plumb the vent hose through all the lights in series.

Those fans are designed for when you have and extra long run of ducting. You can put one of the inline fans to help with the air flow.

They are actually designed to be used in conjunction with regular fans.

Stink's comment--sure you saw it--incidentally could be referring to the 6" blower which wouldn't require a duct reducer. I simply recommend the larger fan so you have more power to work with. No need to run at max capacity and noise. There is actually a great thread about it somewhere on RIU.

Hey dirt, this fanyou list is one I am using on 1 - 1000w HPS and barely is enough once summer hits I am going to have to get a lot bigger one. not sure yet but I think money well spent to go way bigger than needed

thanks again friends..


I was thinking of using these to cool my lights http://www.horticulturesource.com/duct-fan-6-in-line-250-cfm-w-power-cord-p4975/?osCsid=699fc539426b9f8c8556d4a23ed8eb79

will they be enough? one fan for 2 lights in a line bushing air from another room venting into the attic?

Thanks guys for the help...i agree a bigger fan would be money well spent , especially with the summer coming..

i made a couple rough drafts of the fan configuration...tell me which one would work best?

do they make 6inch splitters?

1st one bro. I build force induction systems in my free time. I would use the fan as a blower for cool air, instead of sucker for hot. You typically cant subject them to temps above 160* for very long with breaking something. I would mount the fan directly to the first hood so that it shortens the distance the air has to travel before that U turn...Your gonna lose alot of CFM right there, but I think you can get by.

I was thinking the first one exactly. You always want your fan blowing cool air not sucking hot.

Very interesting DSPEC,,, thanks for pointing that out, i was leaning towards the 2nd configuration but now have learned.

thanks stink,,,Im glad i love to build stuff..

definitely use the first one. air, like water, will travel in the path of least resistance, so split systems are no good. you could possibly getting a 80%/20% if there were to be a crinkle in one of the ducts.

are you sure a 440 will cut it? i have no idea, that's why I ask.

another idea i think i will incorporating is putting a temperature sensor right at the exaust of the fan. if it gets to hot in the summer time, say 160+, i'll start sucking inside air.
