New Grower Exhaust fan question.

[Autogrower]

Going to add a little chamber to my grow, in my Cab grow i got some free space. So maybe keep it like a little seedgrow.

But i am alittle confused, sitting here ordering my equipment.

If you where to buy a exhaust fan that is 125mm flange on it. What dimension would you buy on the ventilation pipe? 127mm? To make it fit over the flange. Or should it be the same diameter as the fan?

All this differen sizes and volumes making me mad.

Thx in advance for answers.

Peace

the outside diameter of the fan flange will be 125 mm and the inside of the duct will be 125mm so it will be a snug fit but it will fit

Ok. So i could also go with the 127mm? It is the only size they got that would fit my fan. I have tubing clamps.

It should fit although you might have a bit of slack then clamp that sucker down as tight as you can get it. If it still doesn't seal completely duct tape the holy hell out of it until there are no leaks! That tape is a lifesaver :thumbs:

Ok. So the right thing is. The same diameter or alittle bigger.

if ya go bigger just clamp it down buddy and enlist a growers best friend ...duct tape

Ok. I see. Yes the duct tape is already used alot in my Cab. :five:

Hey bro,

Just used 125mm fans with 125mm ducting and it works fine, I wouldn't bother. Ducting is essentially foil and wire, I doubt very much you'll have a problem with making it fit, I certainly didn't.
