...you can check out my 1st journal to see how I set it up here (post #7) >>> https://www.rollitup.org/grow-journals/298861-1st-journal-10-strains-seeds.html
...how much it cost to run would depend on how much it runs, obviously.

There are ac unit that the main part of the ac unit is complety outside the room and
Ac hoses go through the wall to a wall mount unit and blow cold air with no in or out,
The main part of the ac unit can be anywhere you want it. Look into sanyo ac units

very nice i understand it a little better, thanks.
but in a sealed room are plants themselves providing enough oxygen/fresh air? and do you need to use CO2 in a sealed environment?
with me having a tent inside a room i can see myself putting a AC unit inside of the room and my tent will stay cool....but do portable AC units need to have hoses that leave or pump in.out of the room? didn't think they just sit in the room with no connection outside....
also the air inside of the room would keep circulating through the tent but the main room is completely sealed, given window and door leaks....

Solarguy I do not use a ac in my room. I have a 10" passive intake hole in the lower part of my room with a damper in it ( meaning it swings open when the exhaust is going and it pulls enough air to open it ). Basically it works the same as a dryer vent. I also have a filter to cover the whole so I dont let bugs and dust and other trash in. Than I have my carbon --> to my 6" air cooled hood --> my 6" 400cfm fan --> vented out of the room. All my ducting is isolated and I have a mattress topper to quite down the fan. Durring the veg I run the light 18 hours a day and my plants are within a foot of the light and the temp there never makes it over 76 degrees. So far I havent had any problems with humidity or over heating or cooling. Hope I helped out some what

The ONLY time you should have a sealed room is if you are adding CO2. If you aren't providing CO2, you need to vent, as the plants will use up the available CO2 in the room quickly, and the air needs to be replenished.

i understand leaving fans on will prvent mold but what about exhaust? any benefit to leaving it on or turning it off? are plants using co2 at night? if not what are they using?

...actually low humidity prevents mold.
...yes, if you have constant exaust you have constant air exchange = low humidity, and a constant 300-500 ppm of co2
...plants need co2 to photosynthesize. Plants do not photosynthesize while they sleep...
...to achieve the perfect conditions ( co2 @1500 ppm while light are on, and humidity @ 40%-60% constantly ) takes alot of bells and whistles....running your exaust constantly is much easier, and cheaper. Good luck.
