I have a 6x5x5 den I transformed at the moment and I am currently not using a cooling fan just the bare bulb which is a 400w hps/mh with digital ballast. I do have a 4inch inline fan which I am goin to rig up a cooling system in the next day for it because I have all the ducting already im just curious to the temp drops without it set up.

Id post this in the general section This is a thread about air conditioned sealed rooms, using co2, dehumidifiers and with discussion centred around IN/OUT vents

I run a sealed room and I dont exhaust air. I pull cool air from another room through my hood and exhaust into the attic. I run co2 so the plants eat co2 at lights on and in return make fresh oxygen and whatever stale air is in the room gets pulled through my carbon filter which sits on the ground and runs 24/7 to scrub whatever stale air. I also open the grow room door about 5 min before lights on to bring in some fresh air. Oh yeah I grow in AZ so every house here has central air and my grow room is a spare bedroom so the AC keeps things cool, If I didnt have it then I'd definitely be investing in a Mini Split AC.

It seems that cooling my lights on a separate circuit is going to help a lot with the temperatures Another question: If i use a mini split, window unit, portable a/c to cool my room... does the air exiting the grow room through the air conditioner not have a strange smell to it as it is not filtered??? I want to be sure of this before it exits the property.

I dont know much about air exchange but I do know all of those AC's will suck out your Co2 unless you are using central AC or a mini Split AC ... A mini split is a really good way to cool a sealed environment, in my opinion the best way if you dont already have central AC.
I used to have a single hose portable AC I used in my closet grow and yes the air exchange stinks like your grow room I made DIY carbon filter with activated carbon from Pets Mart shoved inside some pantyhose. The window AC I assume will do the same.

I run a 14,000 BTU Soleus Air portable. It handles a/c, heat and has a dehumidifier. It has both separate intake and exhaust that can be run outside the grow environment.

I'm still building my room out, it's an L shaped closet that is sealed. It has three separated areas, a work space, veg and flower area. I already tested out the concept with smaller a/c unit but decided to go aeroponics so I just redid the entire closet. I've been working on it for a week now and I'm almost finished. The room has been sound proofed and I made two DIY mufflers for the exhausts and intakes. Everything is very quite and stealthy. You can't even tell anything is even in the closet when the door is shut.

The ventilation works pretty simple. I fill the work area with a/c set at 75 degrees. The veg area has a 4" intake fan and 4" exhaust fan with a carbon filter exhausting back into the work area. The veg room uses 125 watt floro so it doesn't get hot.

My flower room uses a 600 watt HPS that is air cooled with a 6" 400 cfm fan and a 6" booster. The fans are controlled by temperature. They turn on when temps reach 78 day and 70 night. I also run a 6" 400 cfm exhaust with a carbon filter which turns on at 83 degrees. The exhaust fan is combined with an 8" booster fan that brings air in (cool air) from the work room. It's turned down using a variable speed controller which allows me to dial in a slight negative atmosphere when exhausting.

I run a CAP AIR3 to control the exhaust/intake fans and CO2. I've been running some tests on the room for the last 3 days and I'm able to maintain rock steady 78-80 degrees in the flower room and 75 degrees in veg. I'm running 30-35% humidity.

So far this setup maintain 1,500 ppm's, uses very little C02 and is very efficient. I'll be starting a grow journal for some AK48 and Blue Mystic in about a week.

so mini split = good and does not suck out co2? and will i be ok for smell using a mini split? thx

Mini Split = The Best and no you wont be sucking out any co2 and your smell will stay inside your sealed room. Back in the day sealed environments had to be exhausted to bring fresh air in and what not but now a' days they call sealed environments C.E.A ( Closed Environment Agriculture ) where you dont exhaust anything. Of course you have to pull air from another room to cool your lights but basically no outside air gets in or out besides you opening the door. Your AC will act as a dehumidifier and bring new fresh air in back in the early days the technology was limited. We put a scrubber on the ground to scrub whatever stale air is left in the room and to help mask the little odor that hangs around the grow room door, your plants help with fresh air too they eat the co2 at lights on and shit out new fresh oxygen.

Yeah it's been quite the experiment. I'm satisfied with the result though after some expensive trial and error. I'm hoping to finish everything by this weekend and start germinating.

I want to seal mine at some point, im about 2-3 weeks from flower. I wont need an a/c/dehumid till may hopefully.

is it worth it to go mini-split > portable a/c? whats the main difference between the two?

Why are you going with the sealed room vs vented room?

To answer your question of is it worth it: - yes. Think less pests in your growroom, ability to control temperature 365 day a year, ability to dose with co2 without worrying about exhausting any of the co2, ability to insulate your entire grow op (big plus in my books) - basically you become god, you control nature perfectly in your area and as a result get big fat juicy buds... it will cost ya though... The main difference between portable and mini split is firstly the price - a good mini split will cost up to 1000 pounds and a portable will come in at about 300 pounds - you get what you pay for in this game Also the portable will have a smelly single or dual hose exhaust from your grow room wheras the mini split wont, its a split unit 1 part inside the room and the other on the outside of the property - trust me, if you are thinking of doing a sealed room - dont do it any other way - invest in a mini split, you need an excellent air conditioner to deal with all that heat. Good Luck
