Newbie with a Rough Situation but a Hopeful Plan. Please Help!

carbon filters, whether DIY or bought, probably aren't the hard part
getting the right fan and hooking it up properly are the tricks, there will likely be some trial and error involved
some use the ONA bucket setup, bucket full of ONA blocks with the vent pipe blowing in
the ultimate in odor control is ozone, mixed in the outflow, it will destroy odor
ozone is a bit scary, too much and you get something inside you don't want, it can be toxic

Well that ona sounds like maybe a good route for me. I know they can be upwards of forty bucks a bucket but is it expensive to run? I mean do you have to replace the bucket frequently?

I do plan on getting an air filter or purifier and setting it right next to that closet. Recommend any good ones?

Do you know specifically how to set up the ona bucket?

i can't give you the ona setup, but there is a thread that does give some good plans
search this site with google and the prefix 'site:rollitup.org'(if memory serves), the search function here isn't too good
ona is expensive, some say it works great, but there is never 100% agreement
if you want to buy an air filter/purifier, that might be enough
if you can feed your exhaust straight in to the purifier, that might work better
there are inexpensive self contained carbon filter purifiers, i was planning to try one of those if i get a smellier strain

Trying sending them a private message, but I can tell you from a side by side comparison of a 250 cfm booster and a 250 cfm inline....world of difference

Hi guys, bein reading through this thread and it's interested me lol I am also doing my first ever grow in my cupboard, I'm like u doing it on a budget in a block of flats... I'm using 3 cfls atm 2 20w 2700k and 1 13w 6500k and this is what mine looks like after 8 days from sprouted... http://i1121.photobucket.com/albums/l509/stuartcurrie/f9b1da4c.jpg would be cool to compare...

holy shit. what the fuck?!

what strain is yours?

mine is so fucking small compared to that. mine is about six days from sprouting. why is that? my lights are higher wattage then yours.

crazy.

well the thing with those fans is that arent they made for like, clearing rooms?

all i need is to make sure i get no stank from one plant in one trash can, not a grow room. does that make a difference?

shit like these links.

are the inline fans loud?

It's an indica strain and it's White domina, is it really that's weird my 13w bulb is some sort or reptile one maybe that has something to do with it not sure... When u get a chance can I see a pic?? When I say sprouted I do mean 8days after it sprouted above the soil! And all Iv got is a 120mm pc fan blowing in fresh air, not gunna worry about smell really it's only one plant so guna open window and cover the sent with spray or something lol

i have pics on page 11 i think

smaller grow, less odor, usually
i do trashcan(kind of) grows myself, kind of custom build from sheet metal to get the exact dimensions i wanted

ok

what about this for as a fan for a filter?

actually

this guy.

is this all i need? is this link the fan and the filter all together? just hook this guy up and im good to go?

like i said earlier tho, i dont want to go this route if its going to be over kill. or loud. it cant be loud. do you know if that inline exhaust scrubber is loud?

what do you think?

do you think i can get away with an inline duct fan for 20 bucks with a home made carbon filter? its one strain, in a trash can.

i know those big hydro carbon filters are for filtering out entire rooms and not just one plant in one bucket.

you certainly can build your own for this size grow, i don't use the inlines, but i believe their noise is noticeable
but any fan creates noise, PC case fans make noise but they can blend in - sound like a PC - but don't have the push for a filter
matching the carbon filter resistance with CFM/fan pressure is the trick - others have done it, plenty of threads, it's not always simple to tune it to your needs

You're gonna try it aren't you? I just know you are....Ok...booster fan over PC.
You need to really think CFM. How many cubic feet is the set up? How many times do you want to exhange the air per minute.
A PC fan say 75cfm, but if you put a dryer sheet over it, it drops to almost nothing.

A booster fan maybe rate 250, but that is boosted. Free air is probably 150 and that 150 is not the same as an inline 150.
You put a filter on that and the CFM is going to drop considerably as well. You need to pull through the filter and out the box.

Go try it, but also keep in mind that if you are using CFLs (no tube or hood) a lot of your cooling is dependant on air exchange and exhaust. Sure point a fan on the lights, but that hot air needs to rise and escape quickly. And that heat needs to rise probably faster than what an "acceptable" air exchange rate for the box is going to be.

You have your work cut out for you.

ok obviously i dont want to waste my time and money and do more work then needed.

i want to work smart, not hard.

the link to that amazon inline fan, is that everything i need right there? or is that just the filter and i still need the fan?

and, how loud are the big inline fans that youre talking about? are they like a freaking vacuum or do they sound like a house fan?

im planning on having two computer in fans, one in the middle of the can and one at the top.

from what it sounds like, I should have two out fans with filters.

now the fan i havent decided on, its most likely going to have to be a compromise for me. what is a good fan i can get without going up to those huge hydro ones?

or is there a cheap hydro one i can get?

This is the most practical thing I can say.

If you are going to grow in a trash can...which I'm not reccomending.. abandon the idea of a filter. One plant as short as this is going to be can probably be masked.
Get something like an odor puck that absorbs odors, or some of those really smelly crystals and just stick it next to the exhaust. Then go buy one of those timed lysol sprayers and get the ona spray from the hydro store (like $15). It will spritz a little ona in the air every 15 min or so. Your place may smell a little funny, but if you keep this away from the front door and take these steps you shouldn't have to worry about getting busted. Then you can just run your PC fans fine.

Your other option is to private message one these guys who has a filter on a rubbermaid type grow and swears up and down it actually works...personally I don't see it panning out.

ok. yeah, i think im going to take one last ditch effort and try an inline fan from home depot and see what the air movement is like.

im thinking, because the can is in a hall closet, that ill hang one of those gonzo bags that rip out smells.

those odor pucks arent scented right? cuz i could put a few of those on the inside of the can and on the floor of the closet.

its actually a decent sized can, about 40 inches high. so i should be able to get some good growth out of that.

I only spent about twenty bucks on pc fans so far and thats including five fans and two adapters. so i wouldnt be out much trying to make it work. i can probably place a well ventilated can with some carbon in it. make sure the air flow through it is nice, but a little bit of carbon in there should catch a lot of odors.

im gonna check everything out today, probably finish my box, and ill post pictures tonight.

thanks for all your help bro!

Wait a sec, we have a closet? Sorry, I missed that. Personally I would ditch the can and research closet grows.
Now, I can see the idea of a scruber...but you will still have some noise

whats a scrubber?

i mean like, whats the difference?

i felt a bit safer with the can in the closet because i feel like i have more of a controlled admosphere with the plant then the entire closet.

there is a shelf in the closet (ill get a pic for you soon) but i could do a little grow tent from the shelf down.

im just trying to keep things small and if they go well with this first plant, ill make clones and when i know what im dealing with, go bigger into the entire closet.

scrubber means carbon filter, 'scrubs' the air of odor
nothing wrong with starting small, 40 inches is quite adequate for a smaller plant

What Growone said. Filtering the air without exhausting basically. I actually think you will have an easier time controlling the environment in the whole closet. Smaller can be harder at a point. But,

If you can make your closet somewhat airtight....I don't think you want it complete so you can keep air circulating, you could have your PC fans on the can and then an inline fan with a filter on the closet shelf or something scrubbing the exhaust. I can't personally verfiy this yet, but the guys at the hydro store told me (I know, I know) that some of them just leave these can fan combos out in a room when their friends come over and want to smoke (pot, cigs, ect) and it helps with the air in a small room. It would stand to reason, if they can exhaust a closet, they could scrub one as well. If you have some leaks, those can be masked.

An inline fan will make some noise, but if you have a closet door to dampen it, it's just going to be a medium hum like the ac is on. You may be able to build a box around the fan or throw a blanket over it to further silence. They have mufflers, but for your size, you can probably rig something.

I have a hard time seeing this trash can so you may want to post some pics. A tent in a closet, a plywood box in a closet/cabinet, using the whole closet....these are all things I can see working out and would be pretty easy to get help with here. However, a scrubber in a closet could work. If you do go down this road, I would purchase something you can incorporate into a real exhaust in a 2nd build for that closet, so you don't have to double down on cash in the future.
