Grow box small

Hey guys i plan on making a 4 foot tall, 3 foot wide and 2 foot deep grow box. The issue here lies in the odor control, i will be running one plant but i am getting mixed signals from some people saying a simple case fan exhaust 120mm with carbon filter sheeting will take out the smell from one plant and others who say it cant and i need a large setup. I plan to scrog the plant later but for now i need some guidance, its a smelly pineapple chunk BTW. I dont think i understand how much one plant smells being my first grow so if anyone can tell me or give me tips on how to setup a grow box, keep in mind the sound has to be kept minimal im in a apartment.

i think the smell is unreal if i take a flowering plant out of the flower room temporarily. i cannot imagine growing without a carbon filter. i'm a lady, so the making of my room was figured out by someone else for me and i just grow (sorry to any feminists out there! girls certainly could make the room, i just chose not to!) the plant. you'll need venting with that box anyway, you should plan on venting through an appropriate filter to control your smell. vibration sounds? use bunji cords to reduce the noise.

If it's important that there not be detectable smell, a carbon filter/scrubber is really the only main option. The smell of flowering plants is multiple times worse than any sound an inline fan might make. A carbon filter sheet may be ok for a small plant in veg (I don't really know), but I know that even one flowering plant is a big smell risk in an apartment complex. I wouldn't grow at all in an apartment without a good carbon filter/scrubber - no way.

The sound of an inline is nothing once it's connected up to the filter and some ducting - a regular box fan would be louder (hell, my computer is louder than my inline when the gpu fan is going). I would purchase a fan speed controller though, and if you get paranoid or someone is over, turn the lights off and the inline fan down to minimum speed.

Ok these replys did not help at all. At tell us noobs where to go to learn how to build an filter!

Buy a decent purpose-built one with an inline fan if it's important to you not to lose your freedom and/or to avoid a home invasion. Check the DIY section here if you are not worried about either.

I sincerely don't mean to sound like an ass but smell is probably the number one thing that gives "probable cause" to other people (whether with a badge or not) to break down your door, shoot your dog, and take everything you own.

You got a point but say for one big plant in a decent sized box how effective should a carbon filter be 4 or 6 inches and can someone reference the sound of the fan which is also an issue in comparison to like a pc fan with a speed dial. I have just seen inline fans on youtbe and they are loude as shit

I personally would always go with a 6" over a 4" (space permitting). Reason being, with a fan speed controller you can run the 6" more quietly than a 4" (like computer fans, the smaller they are the faster they have to run to move the same amount of air as a larger fan and that makes more noise). There's also less "whoosh" noise from the exhaust end with larger diameter ducting. But if your lighting isn't demanding as far as heat goes (I run up to 600w in my little tent), you might be able to get away with a 4" running at a low speed which would be close to silent and just as stealthy, so I don't want you to get the wrong idea - this is all just subjective and there are a lot of variables.

And just so you know, the noise of the inline is a lot less once it's hooked up. The same inline I have sounds like a jet engine if I run it while not being hooked up to the filter and ducting.

For general noise comparison, the 6" in my little veg tent is not as loud as the fan on my computer's graphics card when I turn the speed all the way down. When at full speed, it is about as loud as a desk fan and not as loud as the portable air conditioner I have in the same room. The sound is lost to background noise easily.

my computer is louder than my inline when the gpu fan is going

take the casing off of your PC and odds are your fan has a lot of dust. if you're hearing it when it comes on that loud, sounds like you need to just use a can of air on it. should help you a lot with the sound coming from the computer when the fan turns on.

It's new - no dust and it's really not all that loud (just a typical high speed fan 'whir' when it spins up).

so just get a six inch inline with filter ducting and a muffler is my idea. I was gona build my own wooden box out of MDF being more heat resistant instead of a tent because i do not like the idea of smell leakage during flowering i need the smell to stay literally inside the tent cause if it leaves my room im fucked
