Separate vent circuit for lights, C02 for sleaed plants

[Undrgrnd Armory]

Correct me if I am wrong, but...........

I could make a 180 curved vent line in my cabinet starting with an intake, bending around through my air cooled hood and out the back of the cabinet again. This ventilation line would serve only the purpose of cooling a 600w hps.


I could then totally seal the cabinet in black/white poly with a zipper door (viewable only after unlocking the tot locks on the melamine doors). This would not only prevent light leaks, but also smell leaks.

Plants would get their c02 via tank and co2 controller. Could I then eliminate the need for a carbon scrubber, free space, and have less noise as a result of a lowered power fan?


Not to mention the added benefit of C02?

Anyone?

In a word, YES!!!

Have the ducting from the light completely seperate from the room (ie pulls air from AND exhausts air OUTSIDE the growroom).

For odor control, you will need to get ANOTHER fan and a carbon scrubber that circulates the air inside the room (and in turn scrubs it). Or you can get a vaportek or ozone. Alot of people using the vaporteks run a search on them. They use almost no power make almost no noise and are damn effective!

So you would have no ventilation for your plants themselves.. in theory it should work since you will be supplementing CO2 but I don't know if there are any other gasses required by the plants. I still think some smells would end up seeping out of your grow someway or another. Now since you won't be exchanging air inside the cab you could, also theoretically, use a standalone air scrubber.. but if you were going to do that you would probably just do normal venting / scrubbing.

wow BabyHughie I swear I didn't copy your post, you just type a little faster.

i think you stil should circulate your room cause plants dont use only CO2...

I grow in a totally sealed room with a co2 generator and no air coming in or going out except for the occasional oscillating fan on the floor

Yes, but plants create their own 02 during respiration.

I know people will have differing opinions on this, but please explain why this will or will not work. I would like thought specifically in the realm of whether or not a c-22 lined in plastic with a zipper door will hold in smells and also whether a plant actually needs any fresh air if co2 is added to the room.

I run a sealed room also... my plants don't get any fresh air all day just co2. My room smelled up the entire house and the drivway in front before adding a scrubber inside the room and ozone outside of the room so be careful. I don't think the plastic will hold in the smell in.

If you seal your room I think you will need a way to controll humidity. An unvented light helps keep it down but once you seal the light and vent it I think your humidity is going to get pretty high.

doin a sealed room w/ co2, I only vent with fresh air for 30 mins a day. shrug, just me, works fine

what would an otherwise sealed room with a window mounted AC be, air wise?

is ALL the air the in the room going to be exchanged out for cold by the AC unit?

 

[Guest]

Undrgrnd Armory howdy, i would add an internal scrubber as stated to eliminate smell, or a vaportek even better less noise. thiough if smells a not such a huge problem, should work just be careful smell is dangerous


mpro ,is ALL the air the in the room going to be exchanged out for cold by the AC unit?"" nope. see them type of units (split systems also) do all the exchanging on the outside bits so you wont loose your co2. them portable ones will (not including the dual hose'd ones). just to clarify good luck.

In a sealed room your gonna need a dehumidifier to run at least during the lights off hours or you'll have the morning dew all over your buds

I don't think you could completely seal your plants off even if you were using bottled Co2 because the plants produce almost (i believe) as much O2 as they use CO2 and since you'd slowly be filling the space with CO2, all the O2 left over would need somewhere to go.

I've never put this to the test, but sooner or later the space would get so full of gas that it would spring a leak somewhere and everyone would be like "that smells gooood."

Not to mention that without proper ventillation mold would probably be appearing much easier, and the humidity would not be regulated simply by approaching whatever ambient levels are because of the interchange.

Sorry if I'm not really answering the question.... and I'm speaking only theoretically, not from my experience.

You could use the slow accumulation of pressure within the growing area to passively exhaust excess gas through activated carbon or whatnot, that should take case of the smell as long as everything else is airtight. Just make sure you put the vent at the top, because the precious CO2 you feed to the plants is heavier than O2 they produce as waste and will sink the the bottom undisturbed.
I think.

Goodluck!
