There are 3 wires coming from it. white/green/black

Pretty sure black is hot-green ground-white neutral.

Anyone have any advice what to do from here?

Yes you're right on...black =hot, white=neutral,=green is ground.
Aside from that what further advice are you looking for?

Take an extension cord of the appropriate length and cut off the female end.
Then take some wire nuts or butt connectors and match the three colors together. Green-Green, White-White, Black-Black. Tie them in and cover with some electical tape afterwards.To lessen the noise you can take a blanket and wrap it around the exposed outer housing after installation. Then tape it to the ducting making sure to leave none of the fan exposed.

The extension cord with have those same colors?

Or just go buy an appliance replacement cord. They are definitely color coded and a little cheaper than an extension cord.

What AeroKing said. I believe I paid around $5 or so for mine, either a 4 or 6 foot I can't remember. Very simple! Good luck with your grow!

Guess everythings on track here... Either a cut up extension cord or a replacement cord, either way they both work...

It doesn't come with a plg because it's meant to be hooked up to a switch in the main wiring...


Oh, and I'd definately use wire nuts... Not butt connectors.

and i wouldnt wrap a blanket around a hot motor either. you can use dyamatt for car stereo installs it as a sticky side just cut and stick the stuff is amazing . the other way is to get high temp adhesive and glue felt/tar paper to alll flat metal surfaces! this will quiet any tin duct work!

My 1000CFM can fan sounds like a jet engine...

Even just adding some ducting and an elbow after the fan makes a huge difference in noise, though it does restrict the flow a little bit.

put a piece of tire inertube between the fan and whatever it bolts too!.this will stop vibration noise!

It's not just the vibration noise. High powered fans move so much air that it literally sounds like a jet engine. Adding ducting after the fan helps isolate this.

If I weren't blowing into the carbon filter, it'd be much, much louder...

Yeah, filters really help quite it down, but I've got a 8" cheap ass valuline cooling 2 isolated 600w hoods, no filter there. That motherfucker really makes some noise.

I wired mine directly using an attic fan termostat. It regulates when to turn on the exaust. The intake has a dimmer on it.

Nice rig job... You know they sell the same thing for a hundred bucks...... At garden stores...

Cool i only paid 26. 74 dollars in my pocket. AS you said same thing, but 74 dollars richer.

yeah, hook to a chainsaw motor. Those fans are basically useless.

how about if your fan only has a red and blue wire??? its a PC fan i think and my cord has three

At home depot the have "power tool" cords.... which are extension cords with the standard male plug on one end, and three wires matching the same colors at the other. They also have 2-wire cords next to them. I accidentally bought one of each and didn't notice till I got home.

I said "F-it", and hooked the 2-wire cord to the fan (no ground). It worked for a week, then I woke up at 3am to loud popping noise.... the wires burned a tiny hole in the fan and was shooting sparks and fire. I immediately replaced the cord with one with a ground..... now I will not die in a blazing inferno.

The cords are $6.50.

My fan is the Home depot 4" $28 inline fan. It's only cooling an econolite $20 150w HPS and exhausting to the WalMart DIY carbon filter. Working fine for me (not counting the death by fire incident due to not grounding).
