Ventilation question

Have 3×3 tent. First indoor grow. Need some advice on carbon filter and fan... looking for something tgats going to work but price is an issue.

Ac infinity is reasonable and a 4” setup should be fine.

Ok Thanks. I keep hearing about AC Infinity.
I guess I should start believing the hype!!
Respect for the reply!!

When possible, oversize your fans and use a fan speed controller...makes dialing in your environment easier and less work on equipment = longevity.

The AC infinity fans are awesome. Little more expensive than the Vivosun fans, but if you buy the Cloudline version, you get a built in heat sensor that will kick to a higher speed automatically to control the heat in the tent. I originally bought the Vivosun version for $175 and then a heat controller for an extra $80, so the Cloudline would have been a better investment out of the gate. Here's the shopping list of what you'd need.

I have no experience with the Cloudline series but I hear good things.

I have the 6" version in my 4X8. Bad-ass fan. (I re-did it after the pic was taken, but you get the idea.) The links I posted are the 4" version of everything I have in my tent. The fan speed auto adjusts to either temperature, or humidity setting, depending on what mode it's in. So if it's only a few degrees hot, it'll put the fan speed at 3-4 but if it spikes, it'll go up to 8-10 to get the heat out quickly...then shut off completely at some point when the temp hits target. Lots of tech for the money.

This is my 4”. I bought a 6” and it was huge! I personally like my 4” for what I’m doing. He’s right. The controller is built in vs buying one and adding it on, which some guys complain it makes the motors whine if you don’t get the right one. I set mine for humidity and it works perfect.

Thanks for the info! Will look into those.

So think I'll go with the cloudline but the g hydro filter is not available here in canada.
Whats the next best option?

AC infinity filter?
