Hey guys -
what exhaust fan would i need for a 2x2 tent with 600w TS Mars Hydro LED.
Was thinking just a cheap one as its my first grow - Black Orchid Eco fans are cheap and have acceptable reviews, anyone know this brand? and are they loud? looking for a quiet fan if possible
EDIT: also, what size? 4"?

I would go with 6". It will upscale to a larger tent very nicely in the event you ever decide to go bigger. You'll limit your options if you go with a 4" system.

This one is 5" - would you say this is too cheap?

thanks for the link! would it be a 4" fan that is the best fit?

as said above 6" would be a better investment and you will also be able to run it a bit quieter, tho you may need a more expensive (bigger) filter to match it with.

Yes. Far too cheap. That looks like nothing more than a cheap inline booster fan. It will not have the extraction properties of a proper inline extraction fan.

This. If you can afford the 6 inch go for it. The AC Infinity fans are super quiet. The S-series have fan speed control only. The T-series have a control module that you can program to have the fan kick on when it hits a certain temp or humidity.

That is not a proper extraction fan. Really that is a duct fan. Quite loud too.
Black Orchid have some perfectly good proper fans. But they will be more expensive.

also consider getting bigger than you need, and using a speed controller to slow it down. This is how to achieve really low volume
