Need some feedback.
My plan is to build two grow chambers seperated by a lung room. In the lung room will be my ac, dehumi, scrubber, etc. And run them on a flip, with Y ducting and automatic dampers, etc supplying the active room with perfect climate air.
But.... my problem is the space i have to work with will only allow a lung room of about 4ft , essentially the space left between after the grow chambers are built.
I know for the most effiency a lung room with equal or even greater volume is best but would this work?

Thnaks Laylow!!
Ha ha .. I wish i had Anti's skills when designing stuff on the computer.
Here is how im picturing it. I cant decide if having the air from the lung room pump in from the top (co2 enriched cool air trickiling down the center and sucked out at the bottom).
Or change it to suck from the top and push from the bottom. Normally you would want to suck from the top, but with c02 it seems like the plants would benefit more from the co2 disbursing from the top down.
any ideas yall?

I think you'll get better heat extraction from the room if you extract at the top. (Heat rises, etc.)
This will work well in your lung room as well, since cold air sinks... so hot air comes into the lung room at the top and then is cooled by the A/C and sinks down and is then sucked into the grow room at the bottom.
I think that will be the most efficient way to do it. If you've got a cyclical system where the CO2 is being maintained in the lungroom, whether it comes from top or bottom it should completely saturate your rooms as long as there's good air movement.
I wouldn't battle physics is I guess what I'm saying. It will reduce efficiency.
Most of my heroes would say that you'll get more benefit from a properly dialed environment than you will get from CO2 enrichment anyway, so why not get the environmental part as close to perfect as you can and then let CO2 do what it can do?
Oh yeah, and Sketchup (the software I use to make my models) is free from Google and it has tutorials attached to each tool that gives you a mini-demonstration of how each tool works. (You can turn this off once you understand it.)

Thanks Anti,, yea i figured that would be better to, but was unsure. Do you think the smaller lung room will be a problem?
The location for this grow requires that i run a closed loop system totaly sealed for security reasons. Im gonna insulate the hell out of it. I wish i could just use maximum venting, but it would be a little risky. And the way the room is it would be hard to find someplace to draw air in. So im stuck with it.
Beacuse its a closed sealed setup, c02 is kindof a must. ( plus i already have all the equiptment) I do plan on running the room cooler then you would when using c02. So at first until things are dialed i will just try to hold c02 levels a couple hundred over ambient.

I don't honestly know. If you're exchanging the full volume of the grow room twice a minute, and your lung room isn't twice the size, you might find your AC running 24/7 and still not keeping up. I guess it would depend on how many BTUs you are willing to throw at the problem.
I will defer to someone with more lung-room experience. (cough... DHF... cough.)

Yea..DHF would definaetly know. Ive been searching everywhere about a smaller lung room and just cant find anything. The mini split AC i was looking at is a mitsubishi 14,000 btu with the DC inverter technology. Those things are made to run constantly for years. It will just have to cool the one 1k bulb at a time flipping back and forth in each 8x8 room so i think that should do. but im not certain. It might even be overkill who knows.

You want you're growroom to have negative pressure. ( wish freezerboy was here to see me shine)
I was going to draw you a nice little pic but, I think I'll just do my best with words....
You want to have your A/C going in through the BOTTOM of both your grow chambers.
C02 is a WASTE if you do not have a sealed environment. You want to be exchanging the air a lot in both rooms and if you want to add c02 you're going to have to make it a closed loop system with no exhausts or intakes so the c02 doesn't escape.
You want the exhaust at the TOP of the growth chambers. You also want the exhaust to have a FAN that's taking out more air then the A/C is putting in. The exhaust from both rooms should meet in a box in the lungroom where the dehumidifier sits.

cool drawing Ursus! Yea the closed loop is what im doing, and the rooms will be totally sealed. No intake or exhaust from anywhere other then the lung. The dehumi box is interesting? is this for the extra heat, and to make sure the air passes through and gets treated before heading back to the grow chamber?
Also, the room will be on a flip meaning one active room at a time (12 hrs) then the damper closes off the one side and dumps to the other now active room. Passive intakes would definaetly be alot easier and more efficient.
I was thinking i could put a small maybe 250cfm exhaust fan (totally seperate from the main exhaust) mounted on the ceiling somewhere in each of the grow rooms ducted back to the lung room to only run during lights off to help cool and dehumidify that room using the lung rooms air.
Isnt one of the main goals of running vertical rooms is to try and keep day and night temps as close as possible? That would make it pretty close i imagine? I could even put that small fan on a thermostatic controller to really keep it close.
The AC low in the lung room is a neat idea!! i could mount it wherever i want and if thats the best then so be it huh!!
I still beg the question of a smaller lung room? anyone.

Maybe the box for the dehumi could just have a mesh wire bottom of some sort so another fan wouldnt be needed. The air would be forced to pass by the dehumi before getting to the lower half of the lung room? But im not sure if just having the dehumi sitting in there would do just as well? especially since the ac acts to dehumidify as well.
I'm loving this grow you have going with your incredibly creative designs farmhouse cat.
Depending on what is above the ceiling of your lung room, you might be able to increase the lung room volume by opening up part of the ceiling to include some attic space. You could even seal off a volume of attic for this by enclosing it with heavy visqueen using ducktape and staples.

wow rabbit thats another great idea i didnt think of! Thanks.
Alright, farmhouse, we know you know what DHF says about keeping temps as steady as possible morning, evening, and maybe even at noon.
So:
Stop sweating the smallness of the lung room.
Do not isolate one room from the other, but design it to exchange both rooms twice per minute, like you were doing an nice non-supplemented open room, llight and dark.
So now your total air volume is more than doubled. (Room+Room+lung).
Set your CO2 for something that won't shut the girls in dark down, like 800 ppm. Your 2x minute air exchanges at 800ppm and no girl is hurting for CO2.
Set your humidity (50%) and AC (86) and keep the air moving.
You should be able to keep both room's environment almost totally stable, night and dark, as the AC will be keeping all the air down to 86... And it should be good year round.
And bobble will be on your door with cookies.

I love cookies! LOL
Im not sure i understand what your saying exactly?
Are you saying to forget the lung room? Or keep the lung room but keep the fan pulling in both rooms 24/7? in reality making the inactive growroom a lung room while its in the dark?
Genious!!! I need a V8! and a cookie!
Yeah. That's what he means, and I think it's a much better solution then having the dark room's vent close off when not lit.
Make it so.
