    I am setting up a sealed room,and need to get a co2 controller.
    I am on a budget and would like to spend less than 6oo.
    I am going to run ac and a humidifier if i need one.
    Do i just need a co2 cont or aa tempcontroll aswell?

    I will have 1 x 1o" exaust just incase of overheating
    I was looking into the sentinals but am open to all
    Thanks for reading,cheers

    Honestly, if you're going for a sealed room, co2, and to also control heat and humidity, on a budget, I think you should wait.

    To get everything dialed in correctly (co2, heat especially), takes a decent amount of cash. Unless you live in cold climate , your biggest issue with sealed room is heat.

    I was going to get a 24,ooobtu window a/c to run.
    What would you recomend i do then? Im interested in saving money but thought co2 was a big part of the cea /sealed rooms.I think im gona run my 1k bulbs with no hood vertically.Im shooting for 85 degrees w all 6 lights on and at 3ooobtu per 1k=18,ooo btu needed at most.If you canhelp me with a better layout heres a list of
    Gear i have:
    12" elecient fan
    8" vortex
    6 x 1kballasts
    7 x 8'' ac hoods
    ebb and flow bucket system

    Thanks for your help,cheers

    I know for a fact that with a little math a fella can just run c02 out the bottle, through the regulator/flowmeter, and solenoid valve set up with timers to reach your desired saturation levels. search co2 calculator, it'll give ya everything u need to know, I'm envious of a 2 ton window unit, I got a 1 ton yesterday 4 cheap at a garage sale. The absolute minimum u need for c02 equipment is regulator/flowmeter with a solenoid valve and either 1 or 2 timers, and obviously a bottle.

    hi I want to try the same thing .but i was going to try a swamp fan.it runs on the same princible as a fan blowing through a wet sheet.Southern poor mans ac.Its nothing more than a fan with a water pump .even with a dehumidifier running it could save thousands in a years time .Or if you run off gennys it allows more electricity for more lights.I use one to cool off my house last summer cause I didn't want my electric bill to go any higher .cooled it off fast.but not as cool as ac .I'll seal off my room as soon as I have the money for the co2 monitor ,regulator.

    thanks, faceoff13, and I hear ya tjizzle on waiting for the controller, I was kinda in the same boat then I started thinking about it, they want $1500 for a c02 controller where I live, but thats more for syncing the c02 release with in/out fans in a conventional set-up (not CGE/perfect room). So, armed with a little knowledge of gases, gas flow thru a given orifice and saturation levels one can figure out your flow time and flow volume required for your size of room and desired saturation level. Then I found this C02 calculator on here that did the same thing in 2 minutes..... I know my idas are kinda hillbilly but my $1500 could definetly go to better purchases, christ, I've heard of ppl growing without PH or TDS measuring devices....


    P.S. that C02 calculator is stickied on indoor growing !!!!

    lol my first two rounds were w/o ph/ppm checking! lol

    Where i live the co2 controller i want is only 4 or 5 hundo...im interested cause of ease of use and for pest controll just pump ppms to 1o,oooppm for an hr and no mas bugs.
    I have seen the calc,and might go for it as my power bill this mo is $1487! thts not even with all lights on.
    To help lower my bill i will flower with 6/12! yes 6/12 not 12/12.
    A hydrofinned heatreducer/exchanger is way cheaper to run for sure but im gettin my ac at HD fer 5oo but im gona charge and pay it off after the cycle.
    Im leaning twards the sentinl controllers,anyone using them?

    be careful of a too big AC unit. If it cools the room down too fast, the humidity/moisture will condense in the room instead of the evaporation coil. This can create mold.

    Yes, you don't need to bundle all the features together. The CHHC-1 is a bit misleading because the total amp that can be used through it is 15amps. That limits your options if you had a lot of equipment that pulled through the one controller. Dehumidifier is easily 5-6 amps. A 12,000 btu ac unit dual hose is 12 amps. Intake/exhaust fans typically pull 1-2 amps each as well.

    I would keep the AC separate from the CO2 controller. It should have it's own temp controller/timer features that work just as well.

    That is one the hazards of running the CHHC-1. If, for some strange reason, the circuit breaker on the CHHC-1 trips, your whole environment will go totally out of control.

    My setup is a CPPM with all the devices needed to run my CO2 on it's own breaker. I then have my Humidity/AC on their own separate breaker/controllers. Lastly, my DRT-1 and pumps are on their own separate breaker.

    I have the CHHC-1 and a sentinel PMX-2 power expansion modual for my 240volt a/c I haven't hooked the a/c up yet because I haven't needed it but in theory this should work. I love the CHHC-1 it does everything I need and is very simple to use. I got mine at a player price of $480 plus tax $520 out the door.

    ac wont work sucks out al ur co2 u need a swamp cooler dehumidifer carbon filter with vortex fan recirculating air aka scrubbing and a matador co2 controller with a blue ox burner. Thats the easiest cheapest way to do a perfect room.

    you may also get a green air controller and co2 tank regulated but its hard going in and out of a house with co2 tanks lol unless u can convince everyone ur a diver

    run the dehumdifier on its on all the time set it to 55 percent co2 1200 to 1800 ppm and the water chiller should have a temp control unit installed on it or if your on a budget have it on a timer to go on every hour for 15 mins should do the trick or run for longer if you c ur temps higher then 90f, optimum temp for co2 enriched room is 90f to 95f. aka hot house

    Thanks I will check those out now,
    I was told window a/c's dont exchange outside air with inside air?
    I know the little portable ones do,but not the window ones...hmmm
    I also read the sentinals peak at 25OO ppm and I read sometimes 1ok ppms is used for an hr to eliminte bugs...Heres oon that goes to 1ok ppm

    The matador is sweet! Shit 8 hundo ?! ouch is that wht you use?

    There should be a lever on your window a/c that will allow you to recirculate the inside air instead of dumping it out.
