using AC probably will double (or close) yield and bag appeal.. I fought it for years...

"oldbean" leads me to believe yer just being a cheap old bastard!??You're right, I know it deep downbut I keep telling myself I can't afford it as I don't sell what I grow
hence considering a smaller fan & led's
If I was a commercial operation, even small scale I would have a/c running for sure along with multiple lights
Peace
consider selling some to close friends..you do have friends that get high, right??
what! you sit home a stay high by yourself!!
no, no...I'm sorry OB, I got carried away..
we all have our directions.. GL brother..

HAHA!! yeah, my friends with the stills. you should put this post in budgreenjrs thread 'you know you live in the country if...'..Lolz been there done that Snook, these days the friends that I have that like to get high do not pay for the pleasure, the same way that when I go round to them I never put my hand in my pocket & I'm always drunk, high and well fed.
Horses for course's my friend!
BTW CheapBastard is the name of a fellow grower from back in the day..I'm sure he's lurking around somewhere
Peace
but I can not drink as much as they can consume.. my work is expensive but they get a real good deal, nothing like market.. guess I was in retail too long..

Yes it is 2016, and power is 86 cents per kW/h. Tack on another 12 cents after you hit stage two. Even with ac in a sealed room you need fans and filters to move the air to and from your lung room. The only extra cost is the controllers . Just do some quick math and you'll figure out your savings on power greatly out weighs the controller costs in 1.5 mts.
Also wondering where your getting a 18,000 btu air con for 300 bucks?

That was a very nice post OG.. complete.. thank you.. scale it up or down... good.
I have a question. kinda ventilation... currently run warm filtered exhaust into attic... florida. the return AC register that I disconnected from the household AC system dumps directly into the attic. All is good... but what would be the ramifications of running that warm (77*F) filtered air into the AC system? Would this affect household AC balance?
Yes it would for sure, it would make your ac work a lot harder
Also what a lot of people forget is the plants never care how you maintain 78 or 86 or whatever temp you wanna run. They just want a consistent environment. Ac or fans or ice or swamp coolers . Doesn't matter. As long as it's a consistent, perfect enviro. You'll get the same yeild and bag appeal running any of the above . Consistency is key

so we're all on the same page, 77*F is a better constant, lights on, than 85*F..?? yes??
but to my question: my house thermostat is set at 71*F at night when lights are off when lights are on its ??? 90*F outside and therm set at 73*F.. my tent temps are 77*F lights on, 71*F, lights off... by 'pumping' that 77*F air only out of the tent into the system and not allowing household AC to put air back into the room makes it work harder??
OG, I wanted you to say it was OK..

I was referring to 78 without co2 and 86 with co2
Sorry I miss understood your question. Sounds like you have everything under control. i have never ran anything quite like that so I can't be 100% certain but it would be easy to test it all and run it a few different ways to see if it is working the ac harder than it has to.
Mid 80's, co2 and humidity at 60-70%, with night temps not going below 70f is when I have had my best results. Have to have lot's of air movement in the room. The way i see it(IMO) the closer you can get your room to a rainforest, the better the plants will do.
EDIT: here's a room i ran that was in those parameters:

Wow 86cent per KW/h in the uk we pay around 13p , yes you do need fans and filters etc to move air still but no way near the amount as you are only recirculating. Sealed rooms offer much more environmental benefits to control RH etc and if your running C02 it's not as wasteful and also easier smell control and less noise. Air conditioning units are very efficient , even in heat mode they give around 8KW of heat and only consume 2.2kw. You can pick up many second hand units for penny's ....

That's 400 odd quid and you have 6000btu to spare which is always wise ..

I thought a sealed room ran independently - i.e., without a lung room; but rather AC directly in the room... not moving air to and from the room... but instead supplementing CO2 — instead of moving air from room to room...
Or am I missing something?

2.2 kW vs 900w.... That's another light I can run.
You have some good points on sealed rooms but as far as smell, there is none with either system if you keep your filters in good condition.
I probably would have totally agreed with you if this was 2 years ago, but air exchanged rooms are way cheaper to set up. No co2 and less work during construction phase,way less power, no propane or bottles to deal with.
U.K. Must be nice . I wish I got power that cheap, for an ac that size would be 700-800 here. I wouldn't buy a second hand ac if it was the sole means of cooling my grow.
Granger- not answering that one lol
Shvmas. You can do it any way you want but your plants near the ac will suffer from the cold and the ones further away will be way to hot, if your going for a perfect enviro you need to use a lung room and you need properly sized fans to move the air in and out fast enough to keep the whole room at the desired temp.. Sealed rooms also need to have a filter for smell. Other wise when your opening and closing doors,you will let some smell out.

Thanks OG, that makes sense. I just didn’t realize that using a lung room for air exchange into the grow room is still considered a ‘sealed’ room. So it sounds as though AC directly in the room doesn’t allow for even distribution, whereas it’s better achieved when using a lung room. Not to mention the cost savings with AC in lung room as opposed to directly in the room...
AC and burners in the room do create issues with plant placement when ceiling is >8-10".
Good thing there is only one way to grow weed.
Peace Bruah
So is using fans and filters but everyones still at it

I'm with you shmavis.. sealed room, no intake or exhaust..
for sealed hood yes... air in, out of the room, no> CO2 enrichment. I could be wrong...

A "Sealed room" means there's no air exchange or air introduced into the grow room from the outside environment. A truly sealed room needs CO2 enrichment to compensate or the lack of fresh air.
An a/c can be a part of a sealed room, considering an a/c unit (well at least a good one) doesn't introduce outside, it out exchanges and cool the intake air (which comes from within the grow room.)
Probably the absolute best way to design a room, (at least for cooling purposes) (though not always achievable), is to seal your air cooled hoods and cool them with passing intake air and exhausted without ever coming in contact with the grow room air. This in itself will lower the ambient temp at least by 10 degrees. But as I said, not always achievable, especially if you're running multiple lights or banks thereof.
But hey...what do I know...

This kinda got derailed and some off topic info I dont k ow how to respond to.
The lung room and grow would both be "sealed" they are two different rooms to maximumize efficiency , in every sense , mostly environmental and lighting purposes, they only exchange air between the rooms so both rooms are "sealed" ,90% of the sealed room i have saw always use a lung room to hold the air handler, res ballasts ,dehumidifiers ,foggers and heaters. Your lung room is smell free because all the air travels through a filter before its sent there and treated by the air handler, dehy, fogger and or heaters. It's the only way to get a perfect enviro. Now I suppose if you had a where house grow you could hang all this in the rafters and it would give it all time to equalize before it hits the plants but that creates other problems normal growers without a refrigerant licence can't really deal with.
You will need co2 in sealed room, lots of people now a days are using 6" exhaust fans to keep some negitive pressure and fresh air in there room to get away from co2 and smell issues. It works well I have done it at several spots , I prefer it to sealed
