Can filter 50 or 66?

[brifunforme]

Which one would you get if you were growing in a secret jardin dr80 with 170cfm fan? I found them both at the same price so I figure go with the 66, but Im not sure if there is a reason I shouldn't. Please let me know your opinions on why to or not to get the 66. Thanks!

 

[Cheeb]

both of those filters are gigantic for a DR80. Can 66 and Can 50 are rated at around 400cfm or so. They are also physically too large for your dr80...where would you put the light and plants?

I'd go with a Can 9000 4" or Can 33 if you must go 6".

 

[brifunforme]

Thanks for the input! I have a growbright filter from htgsupply right now and it did not function as well as I had hoped. So I dont want to pay for another scrubber and have it not work correctly either, which is why I was going bigger for the dr80. Im just afraid if I get too small of one then my whole place will reak again and Im not having that happen on this run, I'll lose my damned mind!

HTG/Growbrite stuff is junk. I started with it all. Junk.

Always buy Can Fans and Filters. Money well spent. Highest quality.

Get a Can 33. The 50 and 66 are way too big for that space.

If your light is air-cooled (6") I'd go with the Can Filter 33 strictly to keep everything running 6" ducting. Attach fan directly to filter. Pull through filter, push through light and out of tent/space.

If your not trying to scrub/vent tent & air cool the light all with one fan the Can Filter 9000 is sufficient. Attach fan to 9000 and vent out of tent.

Provided you attach fan directly to filter you should not have any odor issues. If fan has space between itself and filter you risk sucking in smell before the filter which can lead to odor issues.

Label date on filter when you put it into use and change it every 12 months religiously even though some claim to stretch its use a little longer.

Hope that helps.

If you're growing in a tent, just keep the scrubber outside the tent with the fan exhausting directly into it and pulling air from the tent...works perfectly.
Leave one end of the aircooled hood open so the hot air gets sucked out and scrubbed. I used to do this with can 50's and 6'' vortex fans when I was growing in tents...the temps stayed perfect and there was no odor.

 

[brifunforme]

Right now its the grow bright filter and the light is a cool tube. It is ordered like this; first the filter is attached directly to the fan in the back top portion of the tent,the fan then connects to the cool tube via ducting,then exhausts through the other side of cool tube and out the top of the tent.

I assume it's the filter as to why I still have smell. Everything is completely sealed. I changed the ducting and also sealed the cool tube completely with silicon tape and it still puts off that distinct smell.

Will a can 33 run off of a 170cfm fan? My tent is actually a little bit smaller then the dr80 cuz I had to size it down a little bit.

 

[Cheeb]

Yup - Can 33 has a MIN airflow of 100cfm and a MAX exhaust cfm of 200.

Should be perfect.

question....

question....

if you push thru a can fan what keeps the inside from getting dust all over it and clogging it? when pulling thru you have the filter media on the outside for air filtration.

i grow in a dr 80. here is what i have noticed and experienced. I run 400w through a cooltube. my initial setup was scrubber (200cfm phresh)->cooltube-> fan-->exhaust.
the smell was overwhelming so i upgraded and bought an additional filter. unfortunately IMO no way a can 33 will fit in that tent well at all would take up way to much space. I ended up with a can 9000 because of this. so now im pulling through the 200 cfm phresh filter and pushing out of the can 9000 via 2 inline fans. guess what it still reeks 2 weeks from harvest and im well below what the filters are rated for.

 

[Cheeb]

So.. you've got the fan directly on the filter ..PULLING air through the filter?

Your initial setup more then likely had smell issues because your fan was after your cooltube and not in front of it on the filter. Smell is getting sucked into small pinholes in your ducting - thus bypassing your filter.

Set it up like below and you shouldnt have odor issues. At least not when your tent is closed and you are maintaining negative pressure. (tent walls should suck inward)

Filter/Fan --> Light --> Out of tent.

And ensure your humidity is kept low (around 40%). Once these carbon filters absorb a reasonable amount of moisture (say existing in a high humidity room for a period of time) - they lose their ability to absorb odor.

I would advise AGAINST pushing INTO a filter. They are not designed to be used this way. If you DO want to do this for space concerns I'd recommend taking the white pre-filter off of your filter and balling it up and stuffing it into the filter. You need your air "dust filtered" 1st - otherwise the carbon will not last long.

Hope that helps.

That last post is not true at all, you can pull air thru a filter just fine. My set up is

open ended cooltube-->ducting--(out the back of my cab)-->fan-->scrubber

The scrubber works just fine and I have not had any smell issues with that configuration. The way to keep dust out of the fan is put some nylon leggings over the open end of the cool tube and it will catch most of the particulates that get pulled in there. At the end of your grow cycle you can see how much crap is getting caught in the nylon, and it is quite a bit!

I run 600HPS' with Vortex600s and Can filters in my boxes. I've used Can50s and Can66s. Given a choice, I'd opt for Can50s - they hold a bit more carbon, and they're shorter, easier to place depending on the environment. As far as effectiveness, both are equal as far as I can tell. Can50s lasted ~4 years @ 24/7, and Can66s are still fine after ~3 years.

Here is a link to a DIY Carbon scrubber filter tutorial that uses easily acquired plastic mesh grow baskets that is very easy to fabricate and can be generally constructed for about 20 to $30 US dollars in materials (fan not included).

A can filter 33 is only 12 inches outside diameter and 13 inches long. That won't take up too much space up in the top corner or in the back top of the tent. And I think the way your exhaust was set up is one of the main reasons you prolly had smell issues.

You were not only pulling air through the filter, but you were pulling air in through openings in the cool tube/ducting/anywhere there is a opening.

Thats why I have My filter then my fan blowing through the cool tube and out the tent. Thanks for all the input guys!

i use insulated ducting totally sealed. believe me that is not the issue. also nothing wrong with pushing into a filter idk why you have an issue with that especially when its already getting filtered once by the time it gets pushed through. I live in CO and RH is a non-issue mine peaks at 33% during the dark period.

@brifunforme- no every seem is taped and sealed ive tested it thoroughly its sealed the filter was just not cutting it. true you could fit the Can 33 in the upper corner but i utilize all my tent space with my cooltube strapped to the top of the tent so for me it would not work. if you want to grow smaller plants sure ti would work but you would lose the top ft of your tent unless you have a really small hood.

I never said it doesn't work. I merely said that I didn't recommend setting it up that way. While it may take care of your odor concerns its not the way Can recommends setting it up...the pre-filter is on the outside of the filter from the factory meaning they intended it to be pulled through - not pushed into. Pushing into the filter can lead to even "wear".

Whatever works though.. thats what matters.
I pull through my filter now and push through everything else because I have ran into odor issues otherwise by sucking smell into my hood bypassing the filter.

I realize space is a luxury in these smaller tents and you can use all of the overhead space you can get so putting the filter outside of the tent does sound like the way to go if IT WORKS for you.

Most people vent for heat concerns so having a filter on your exhaust exit would only be applicable if your not actually venting your space completely, but just dumping that air into another room or something.

dman,
your filter has to be shot or just a crappy make...or your variety is just a really stinky strain. I once had some super skunk that smelled like fresh roadkill in late bloom and no amount of scrubber/ozone could rid it completely.

 

[GRINKEEEPER]

I honestly would always go with a much larger can and fan and put it on a speed control.. by the way.. you can buy identical speed control units by searching out ROUTER SPEED CONTROLER.. same units as hydrofarm for half the price

 

[dman16]

yep i got scammed and bought a speedster speed controller i keep my fans running about 70% i would say.

the filter brands were Phresh and Can. the first harvest with just the phresh had the best smell control in my opinion, strains were not super stinky either though.

this time im running bubba kush, OG kush and chem 4 so ya the strains are definitely a factor.

You can absolutely push into a filter, it all depends on your setup. They are designed to be run both ways. I know this, because I push into one! And it works flawlessly.

From CF Group's own FAQ:
http://www.canfilters.com/faq.html
Can you push or pull through the filter?
You can both pull through the filter or push air through the filter, if you are going to push air through the filter it is recommended to take off the outer pre-filter and place it before the intake of the fan so you can remove dust and dirt particulate before it enters your fan and filter.
