Ive got approx 450cuft room split into veg and flower so pretty small.

Tried to do sealed room but not working and still in veg and smell getting out. About to add more lights so would either have to use ac or exhast vent to deal with heat.
Using diy cob leds (cxa3070s, vero 10s and 29s) so heat is not a huge issue. Smell is all I am concerned about and temps will be fine once there is an exhaust.

Plan is to get a Hyper fan and I guess a Phresh carbon filter unless there is something better. Was looking at the green gator filters but price is even more.

Also looked at iPower filters as cheap but read some bad reviews on here.
Also looked at Foothills filters or DIY options but running out of time as need to start flower this week cause plants are getting too tall so just need ti make a decision and buy something.

I think a 6in Hyper fan would work for $142. Could go with 16" or 24" filter for total of $269 or $284 (I would go with 24")

I could do a Y to two filters but fugure cost would go up. I just plan to use pvc pipes with two 90s on each end (with black paint on inside if req) to allow air to flow beteween flower and veg room but not allow light to get thru.

More expensive option would be to go with an 8in Hyper fan run at 30% so approx 200 cfm. Really slow so really quiet. Still prob use more power than the 6in but not really a huge amount anyways (35w vs 75w). It is $176 so with a 24" or 39" phresh filter would be kike $333 or $368. Think 8in would be nice but overkill. The 39in filter would also be nice as I really need there to be no smell as it will be exhausted into adjacent unfinished room. I can put an Ona gel in exhaust like above post if needed. I dont think noise will be an issue with either fan.

Also do I want any intakes or just allow air to seep in thru cracks. I had planned to use 2in soffets as intake holes.

Have to figure out where to put filter as I cant fit in flower room or will get in the way of light.
You can achieve your odor control needs with a 6" fan with a Green Gator Filter, so you can save some money there. You also can run that 6in fan at a slower CFM and reduce the noise as well, without losing any filter efficiency. I would be careful about putting too many Y connections or bends in your ducting, the more bends and splits, the greater your loss of airflow.

Regardless of which filter you choose or which direction you go, i hope that everything works out for you. Im a filtration nut so let me know if there is anything i can do to help

That is true...Gator probably knows all the equivalents....

...I am not recalling them off the top of my head, but they were
things like "a 90 degree bend is like adding 20 feet of length"

Good luck all!

JD

P.S. I have found that there are breeds that make this
problem practically unsolvable. I do a great job...survivable...
....but if the wind is right...to *my* nose...I will get the occasional whiff.

JD,

your on the high end but not far off. The variance of adding a 90 degree bend can be anywhere from 10-20ft of extra duct just from the bend. It very heavily depends upon the type of duct you are using.

Odor Control. GoPlus Air Purifier and Sterilizer.

I toggled the idea of getting a carbon filter and fan, but I've used Ozone before and it really does a great job. After doing quite a lot of research, I decided to get this GoPlus Air purifier and Sterilizer from ebay. Its $86.99 shipped.

What does this do?

1. It has a 400 CFM internal fan, with 5 settings. It's loud, but moves a good amount of air. Don't believe the ad. It is certainly no where near being whisper quiet.

2. It has a BIO-UV light that can be turned on or off. What does this do? Kills germs.

3. Purify mode. I think this feature is what kills mold, mildew, bacteria and cleans other odors from the air. It has 5 settings and off, the manual states at the first setting it will clean an area of 0-500 square feet. At the highest setting(5), it will clean up to 3,500 square feet. The unit has an away function that will set a timer for using the unit at the highest settings. But, the manual states this function should be used only in unoccupied areas. I am pretty sure this is your Ozone Generator function. It has Photo Catalytic Oxidation Technology. And I smell that grassy smell like an ozone generator gives off.

4. It has an Anion indicator on the display, which indicates the negative generator is on. That generates negative ions to attach to airborne particles and sinks them to the ground.

5. It has a main power switch on the back of the unit, to disable it for maintenance and a small power button on the front to operate the unit. It also comes with a tiny but, very useful remote. And the display is pretty cool, letting you know how you have your machine set. And the owners manual is pretty clear on how to operate and maintain the unit.

Cons.

It is very loud. That's ok with me, so are most fans with some oomph.

Maintenance. It has preset functions to let you know when it needs cleaning and maintenance. The manual is very good at explaining this. But, I hope it's not too high maintenance. I dunno if this is gonna be a PIA yet. Jury is still out.

Be careful. Only use the purification settings at the level you need. You don't want to overdo it on the Ozone.

Conclusions. Right out of the box it is working great in the smoking room on the lowest settings. I smoke cigs and it always smells funky. After about 30 minutes initial use, I walked out of the room with a cigarette still burning in the ash tray. When I came back in the room several moments later it had just a tinge of that grassy smell. No cigarette or other funky odor at all.

I don't think this would be a great solution inside your grow. But to clean any residual odors, germs, mold, mildew and bacteria, this would be perfect to clean the air just outside of your grow area. I am sure I will move this one around the house where needed at the time. I have some dogs too and they are old and can be stinky.

I still think a can/fan inside the grow area is the best solution. Just thought I would share this as added air purification/sterilization outside in the more common areas of the house.

Like I said tho. It's still brand new so.... Not a reco yet. Jury is still out. Shipping was free and very fast too. Let me know if you have any ideas, caveats or whatever. So far I'm loving it.

This seems like the place to ask this question. So I have a tent that's 36 wide and 2 feet deep. I have to put the tent in my closet right now their is no where else for it. When it's in the closet the two 4 inch flanges are flush with the wall because they are in the back of the tent. So the only ones I could use are the 6 inch flanges. Now my tent is only 28 cubic feet so I really don't want to use a 6 inch inline fan when they move like 423 cfm that would be way overkill. So what other alternative do I have? Do I really even need a filter when I'm only growing one auto?
 
Are there any good guides for micro scrubbers? Also what small fans would have enough backpressure to overcome them?

My initial thought is that a sandwich design filter would work best for low static pressure fans? For example: Fan->Carbonx1''->Fan->Carbonx1''->Fan

You know, while true "ozone generators" are not healthy if not used
properly, you can still get an old "negative ion generator". The emits
charge particles that make particles clump and fall from the air. They
take very little energy and improve the air quality noticeably.

Ionisers should not be confused with ozone generators

JD
ionisers trick you for a few days then after that they have no effect on odour removal imo
they do make a regular cannabis free room feel fresh though

ozone does actually work, but its a learning curve working out how to use it without hurting the plants

I must take your word for that SD...I bought one for health
reasons and my wife stopped coughing while settling for
the evening once I plugged it in.

....but removing these odors might just be beyond one.

I do like mine, I got one for the man cave (this is like, literally,
20 years ago) when I got the one for the master bedroom.

use the 6" flanges with your 4" lines, it should pull tightly enough to keep all the light out (which shouldn't be much of a problem in a closet). You do need one unless you want to take a chance and hope you get a low odor pheno. Better safe than sorry, though, because even "low odor" strains have smelly phenos.

I'm currently using a very small microcab with an led light. Since I don't get much heat, I don't need as much air flow as my 4 inch inline fan runs to push through my carbon filter. I plan to add a two section tent totaling less than 64 cubic feet also using led lights.

What is a good way too just kill odor for the whole room that isn't too noisy as it is next to my bedroom with a shared bathroom.

Is it possible to run an ozone generator enough to kill odor but not be harmful to people or dogs? Like a minute on and several minutes off, or is that bad for the generator?
Thanks

I am pretty sure that what you want to do is insert the generator
between a fan and an exhaust port on your grow area.

No expert though. Good luck.

Best thing to do with ozone is to connect the exhaust fan to the ozone generator and then to a carbon filter. This way you can kill the odors, and also remove the ozone and reduce the harm that you can cause yourself and other members of your household. Carbon and Ozone love each other so its always good to use them together to remove your odors.

My problem is the noise of the fan to push through the carbon. Especially since it's such a small cab, and needs such little air flow as the led creates much less heat. Plus making new cans means additional large fans, filters and noise. Eventually I'll end up with a room full of tents. Ha

Well if you are running Ozone after the fan into a carbon filter, you actually can get away with a smaller carbon filter than normal. Which means you can reduce the airflow. Carbon is fantasticly efficient at removing Ozone from the air, so that means you can do more with less carbon. Hopefully this helps you out to reduce some noise in your system

Let's see if I can explain it right I had guys do the work for me lol.
I had two holes(intake&outake) installed in the attic. I'm pulling outside air through my lights that vents out the opposite side back outside all exiting through the roof(straight up). No smell there.
In My flower room I have a huge carbon filter sucking air in and pushing it out into another room with another carbon filter( I call it my air cleaning room haha) the room is specifically to filter the smelly air. It also vents through the attic out of the roofPlus I put drywall up everywhere over windows etc made my own new walls. Sound proof and smell proof!! Carbon filters work great. I don't like Ona, it's a hassle to maintain I think. Gotta move it around etc.. Hate it. I like to keep the air moving and push it up so its not creeping around in the vicinity. With out checking it every few days or weeks. You know the carbon is good for months....

anyone ever heard of problems with ventech fan/filter/speed controller combos? doesn't seem to work 100%, doesn't even seem like 80%. even with PLENTY of negative pressure (tent is sucked way in) this thing doesn't seem to really do the job. the only other thing i can think of is the inside fan runs 24/7, maybe it is pushing air down away from the CF and making it escape out toward the bottom of tent? BTW - setup is filter-->ducting-->inline fan-->ducting-->room

@ Gator mixing ozone with carbon fitration can be dangerous: CO gaz is created and carbon can heat up till burning.
wouldn't advize so...
