Is a scrubber necessary in a closed system???

[Guest]

Helping a friend put together a closed system and don't hear people talking about using a scrubber much in a closed system. Since the only time scent leaks is when you open the door if this is not an issue are there other benefits to using a scrubber in a closed system? I guess a scrubber could be hooked up and when the door is opened a fan could come on to create some negative pressure to ensure no scent leak. I remember someone awhile back who said a scrubber helps control things like mold/mildew problems.

Anywho...thanx...

I use a scrubber in my sealed room. It will help clean the air and will keep the smell down. Nothing is every completely sealed. I don't have any exaust hooked up to it, I just have an inline fan set on top and it recirculates room air.

^^Me too...it keeps the room completely odor free since the same air gets recirculated through it so often. If you're running a sealed setup, you can get away with a smaller scrubber/fan than if you were exhausting the air since the air will have alot more contact time with the carbon since it'll go through it multiple times.

If you're using co2 enrichment do you still want to use a scrubber?I use the vaportek optimum 4000 in my sealed room I'm real happy with the results.I installed the first classic neutral cartridge on Nov 1 and will be changing it out today.The 120 day carts really only last about half that long.Nontheless my odor problems are toptally a thing of the past and I will pay any price for that lol

hey Skeletor, theres that vaportec 0 4000...i need to ck it. how much$? so. cool the lights. tanks. reg. air flo meter and solinod...DUDE ...REDUX....THANK YOU FOR YOUR HELP!!!i appreciate it BIG TIME! would something like a ionic breeze do it?..i really need to stir the air when enriched...so, sm. carbon filter,w/ fan= clean and stir.
i need to be able to say MY oder problems are a thing of the past!

Ionic Breeze's are garbage. Conumer Reports test of that showed it actually, almost, doesn't work.

OK bro...I did a little research and found the Vaportek 4000 will cost about $150 online and replacement filters are about $60. Following Skeletors advice of replacing every 60 days means the yearly cost for filters will run about $360. First year cost would be $510.

If you buy a Can 2600 filter, 94 cfm, for about $110 and a cheap squirell cage blower to match it, prolly about $100 max, your first year cost will be about $210 as the filter lasts 12-18 months. That setup may work fine but...

Step up to a Can 33, 200+ cfm, for about $140 and a 4" Vortex for about $110 and your first year cost will be about $250.

That bargain Phat filter is nice but when it would come time to replace you'd be spending bigger bucks and you would probably have overkill on odor control and air circulation driving that thing with a larger fan and uneccesary expense. I vote for the Can 33/4" Vortex option. Check one out and it should be pretty small and hopefully easily fit in a lower corner of your grow space. Add a length of duct and blow the air into the opposite upper side of the room pointed slightly down for better circulation and stirring. Draw the air diagonally through the room somewhat. The 2600 option is nice as those filters are super small. If I remember right your space is about 460 cubic feet so it may work fine. Squirell cages are noisy and maybe buy a 4" Vortex and tone it down with a $30 300 watt solid state fan speed controller as you don't want to overdrive the filter.

Obviously the Can 33 option will be better for air circulation and stirring but I assume you have some oscillating fans??? You could always mount that 33 in the attic above your room like you were going to do with the Phat but you'd have to build a small airtight enclosure. If you do remote mount any filter in teh attic you'd really need to go with 33 and max air flow from the 4" Vortex to overcome any line resistance. To start you'll lose about 10% flow through any filter.

Hope this helps...Happy New Year bro .

If your running a "closed" system, how do you manage to keep temps down? Air cooled light is only option there

How do you plan on exchanging the air inside whatever your growing in? I would think you would be more suseptible to mold and fungus by simply re-circulating filtered air back into the growspace

If your going to use a scrubber, why not then simply vent the scrubbed air into your attic space (sounds like that is an option)...This would also help control temps and get some fresh air into your space...I think your plants would also benefit from fresh "new" air

Just my opinion

He's creating a closed system with CO2 so no need for venting to get 'fresh' air and the lights will be sealed and air cooled. He's also got an air conditioner installed and ready to go.

Thanx for responding...

Joe...The manufacturer claims it's good for up to 20,000 cubic feet but saw other sites only claiming 2,000 cuft. It uses a dry vapor dispensing system and not activated charcoal. Still looks like a very sweet unit and it's only 5" x 5" x 12", 10 fan speed settings and about 5 lbs.

Oh yeah...kicking up to a Can 50 and 449 cfm Vortex only puts you at about $300. I'm not knocking Phat filters as they seem pretty damn good and appear to be much small than the same size (air flow) Can filters. Maybe I'll get a Phat next time.

I run a sealed room with an sinky stain... it SMELLS! even with a srubber it still leaks a lot of smell. be careful!

 

[Guest]

so its a can 33 /W/ 4" thanks redux. your help is awsome.have a great day.
thanks Gronut and DaNapster every bit helps! P>joe

Hey man...you know your space and I don't. A properly sealed room should not leak anything. I'm talking about using expanding can spray foam in outlets and light switches, tubes of caulk sealing anything that even looks like it might leak, taping up any leaks in the hoods and ducting but doors are the real bitch to deal with. Seems like metal doors with magnetic weatherstripping are a great start. I've used those and even caulk the corners cause there's gaps in the weatherstripping. Threshold's are a pain.

You know your budget and I don't. I always try and overengineer giving me a margin of error. Overengineering ='s more $. I don't mind as I want the best and sacrifice some things in life. The greater the airflow and the larger scrubber size the more you're assured there will be no odor. When you open the door stink will escape cause you have no negative pressure in a closed system. This can be resolved by using a small scrubber and fan that you switch on before you open the door. Every problem has a solution if your wallet can handle it.

The difference between good and great weed is genetics, medium/nutrients/feeding AND environmental control. Buy the best you can afford....always.

Hey man, use a scrubber in the room, it will keep the air circulating and clean. I set mine up in the middle of the grow space and let it blow straight into the ceiling. Plant's love it and it also circulates CO2 supplementation. Sealed grower, Berryhill
