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.

good informatiom avgdude7

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.
