Anyone using a carbon scrubber in sealed grow area?
- Thread starter JBLUNTS
- Start date
In the grow room it is not doing much except getting clogged...you want your outtake venting to go through the carbon filter. * If you use an ionizer after the carbon scrubber make sure that the intake air for the plants is not the same ionized air or you WILL have BEASTERS no matter what. Make sure you have a sealed environment or the air cleaners are worthless. Hope this helps.

If it's completely sealed, are you not worried about temps climbing? What size light are you using? It's best to have a intake somewhere low to the floor to get cooler air from the floor.....and have the scrubber inside the enclosure/room....and have the scrubber towards the top of the room/enclosure. The blower will pull the hottest air from the top, thru the scrubber, outta the enclosure smelling nice and fresh.
But to answer your question, yes it will still clean the air in the enclosure. But I'm curious as to how your going to deal with temps though. Usually the scrubber/blower system is also part of keeping the air circulated and controlling temps/gas exchanges(more Co2) as well as humidity. Hope this helps ya somewhat

I know what I'm going to do. Since this sealed space of mine is a closet...with a doorknob. I'm gonna take the doorknob out and use it for an intake whole. It will be smaller than a 4" duct but enough air should still come through. I will then use a 4" duct carbon scrubber inside at the very top of closet. Do you think that will work ok?
I doubt that will work...you are better off covering the closet top to bottom with panda plastic, and using thick and multiple layers of hvac tape building a 2x4 frame to hold both an intake fan and an outtake fan. Then use c02 in the in duct and have the carbon filter on the outtake. you want the intake low and the outtake high. This should give you the best results...or use led's and try that method.
My 2kw room is going to be sealed once i'm done with it. you should make the intake about twice the size of your exhaust assuming you are using passive intake active exhaust. So if your exhaust is 8" @ 740cfm make sure ur intake is 16" or two 8" holes.
Edit: forgot to inform you to make the intake at the bottom and the exhaust on the top, opposite side of eachother. obviously because hot air rises. Lets just say I live in one of the hottest areas on the planet and my temps range between 75-94. good luck bro

Dang...
The way my closet is I will only be able to have one intake hole (door knob hole) that I will attach a 4" ducting to that will go to the floor of the closet. I will put a 120mm PC fan (115cfm) between the doorknob hole and the ducting blowing any fresh air in that will fit through doornob hole. I then planned to have a 4" eco plus fan and scrubber at the top of the closet.
walker_so: Do you think this would work using that carbon scrubber with such a small intake hole and the rest sealed?

Sounds like he wants to exhaust the air back into his closet... Have the one hole for an intake and thats it.... Problem is thats probably not going to work...
The temps i would think would be out of control... You would simply be moving hot air around your closet and not actually getting rid of any...
The intake at the doorknob won't do you much good unless you have an exhaust hole so your fan is actually taking air from inside and pushing it out...
More or less what you would want to do, would be to put another hole in the door, or if your renting go by a cheap replacement, and cut 2 holes.... One in the bottom for intake and one in the top for your exhaust... Then hook your fan to your scrubber, so that the fan is pulling air through the scrubber and, blows through ducting to the hole on top of the door....
Hope this helps.

To answer you're original question Jblunts, yes, a carbon scrubber does work in sealed rooms.
However, your real problem, as Rookie pointed out, is temperature.
Most sealed room systems utilize a ducted exhaust portable A/C to cool the room, and a CO2 system. You must have some manner of cooling, as any kind of lighting will generate heat, and if you do not vent the heat the room will eventually become too hot for your plants. Likewise, with no fresh air being drawn into the room, the plants will eventually use up the available C02, and die of suffocation.
In the situation you're describing, you're gonna cook your plants if you don't exhaust that hot air. A scrubber and 4in fan will remove the odor, but there's not gonna be any odor when your plants die from the heat
If you'll provide us a little more info on your proposed setup (room dimensions [Length Width Height], lighting type and wattage) we could provide much more effective help on setting up your room.

Just another penny to the pot. If you go with the spare door to/or cut holes in the door, put them on the side with the hinges so when you open the door you don't rip your duct work off each time. I'd shave an inch off the bottom of the door for an intake, pop a hole to the attic and push all the heat out there. Good luck, keep it simple.

My closet is 2.5' x 2.5' and about 8 ft tall (or however tall the ceiling is in my apt).
I'm growing 5 AK-48 and 2 White Widow x Big Bud under a 2 foot long T5 tube fixture (tek lamp). That is another question I have is how close to keep the T5 fixture during veg. Right now it's about 3.5" from the top of leaf.
I'll be switching to either a 250w or 400w HPS at flower time, not sure which yet.
My girls are currently sitting in a 18gal Rubbermaid DWC w/ airstones (thinkin about swithing to ebb and flow but not sure). They've been in for about a week and roots have not hit water yet. I'm anxious.
So as is right now I have no cooling except for 1 oscilating fan. But I also don't have any odor so I can leave the closet door cracked. What I am worried about is when I do have odor what will I then do for cooling and odor.
Changing the door and putting come 4" holes at bottom and top sounds good but I just don't know about getting the door. Would look kinda funny carrying a door into my apt...

You could use a piece of plywood cut to fit as well....
You need ventilation unless your running co2 as stated above... Once you throw that HID in there it's gonna get hot.... REAL hot.....
The fans that you have will do the trick perfectly if you can find a way to vent your exhaust....
Seeing as how punching a hole in the wall or the ceiling is out. The door is your only option aside from buying a 3-500 dollar portable ac....
Just thought of something.. You could use doorskin as well... It's like 1ply of plywood. Same stuff closet doors are made of. Cheaper than 3/4 inch ply too...
Well good luck and I really hope you get it all sorted out.. I wanna see some of those buds... :wink:
Oh yeah... You can pretty well put those flouro's right on top of your plants... Within an inch should do fine... They shouldn't burn, if they touch the lights, closer is better with flouro.

These T5's are kinda hot though. It's between 76 and 85 degrees near leaves with it 3.5 inches away.
I have a question about venting my exhaust and using a carbon filter. How would that go?
Would I have my fan, then my scrubber, and then what? Would exhaust attach to other end of scrubber or would it be seperate from scrubber? How many duct fans would I need cuz I really only want to buy one.

I once helped set up a grow room, and we got LUCKY! In the closet was the attic access! All we did was cut a piece of plywood same size as the attic door, cut out the hole for the exhaust in the plywood, and put it place of the original door. I have also cut a hole in the ceiling of an apartment, in the closet, and fixed it after the grow was done. Sometimes, you gotta do what you gotta do. As far as what rookie said, you could also do that, they have a white panelboard available at HomeDePot or Lowes for like 13 bucks, put that in place of the door, and cut your holes in there. It's extremely reflective white, durable, easy to clean, and best of all, CMEMORY!

why not just build a sealed box to use in your closet?
less of a design headache?

What you do is mount your fan where you want it, then you want the scrubber on the intake side of your fan and the air blowing through the ducting out of the closet... Simple enough....
Then you just need a hole or two on the bottom of the door/plywood whatever for your intake...
This way when your fan is running it's creating a vacuum in the room because it's blowing air out.
Creating negative pressure is key to having your scrubber work properly. More air going out than coming in....
With my limited skills i'll try and draw it here....
You'll need a bigger fan than a pc fan btw. Small squirrel cage fan or a centrifugal fan... Min i would think would be like 200 cfm...
