Help choosing exhaust fan to my tent

Suck air and pull out air sound like the same things. Do you have a light you need to cool or a filter for the smells? Are you using some kind of ducting or are you just trying to provide fresh air? I guess I'm asking what's the purpose of your fan.

 

That's not the type of fan typically used for growing. Those are very week. Google inline grow fan. Vortex, can fan, hurricane, are some pretty good brands I've used. What you have there might remove the fart smell from your bathroom but they wont be practical for growing.

 

I understand. If a fan is pushing air out then you don't need one to pull air in, air will come in by itself as air from the fan leaves the tent. Like Killset said, the fan you show is a weak fan but you won't need very much air flow. If you rely on your tent to keep out light then it's easiest to use a duct fan like this one and a short piece of ducting. You could probably figure out some kind of light trap that would work with a box fan like you pictured but it wouldn't have much air flow.

 

Once you go putting a light and equipment in a grow space you will need one bud. This isnt one of those things you can half ass unless you want issues. Theres cheaper ones out there then $100. Dont you see all the threads about heat issues? Most of those are from people who half ass it. If you're not going to be serious about it theres no reason to waste your time, plus money on other things needed.

 

I've given you brands I recommend. I dont cheap out though, if you go cheap what you choose is on you. I look at it like this, I dont have to buy weed so no matter how much I spend I'm still saving money.

Now your tent is just under 48sqft so you'll want something that turns over the air atleast 3 times a minute. So you'll need atleast 146cfm fan or larger. Now that's 146cfm on an iine fan, 146cfm on a bathroom fan or duct booster wont be as powerful because they're rated differently to be used in conjunction with other fans. Personally I double that figure and use a speed controller to dial the fan down. So I would be looking for something 300cfm or more. This does 2 things. It gives extra power if you ever need it, plus a larger fan ran slower is more quite then a smaller fan ran at full blast. If you get the fan above you will need a speed controller but thatd about the size i would be after personally

 

I already commented on that one had you completely read my last post. I dont know the brand but that's the size I would be after personally. You will need a speed controller to dial it down some though. They're $20 or less

 

I understand not having the money but just so you know the extra money spent is for years of warranty cheaper fans usually have 1 year and the three listed more expensive fans have 5-10 year warranty. I mean obviously better materials used but I think warranty to me is what makes the extra money worth it

 

That is like one of the fanciest fans out there, I was going to get one but already had a hurricane so I bought another one of those. You said you didnt plan on getting a carbon filter if I am not mistaken, if that is the case I hope someone can jump in and let you know if it is a good idea. They have 4 in fans and I think if you are not going to use a scrubber then that should be enough depending on how far you have to get the air out of the room.

 

Carbon filter scrubs the smell so if it is not legal where you are it is a mist have. Other than the smell I do not believe a carbon filter is needed. But If you get quality products for your setup it is a large initial investment but alot less than buying weed all the time. For a carbon filter I use phresh brand.
