Need co2 help

I would guess you could go through a lot of tanks in a day with that unsealed room. LOL... Burning charcoal to make co2, in a vented on high unsealed room, just makes me laugh but firemen will not. LOLOLOLOLOL ROFL....


Expensive is a better word. And ofcourse there are degrees of 'Unsealed'.

My largest concerns with running co2 is that if enough co2 builds up in your grow-op it can be harmful or even lethal to human health. If people break into a commercial op with a system malfunction they could black out and be dead with no chance of escape. Co2 can only be used when the lights are on and has to be cleared from the air before the lights go out. Your plants need o2 when the lights go off. I use charcoal to generate co2 for my personal op and I only line up enough briquets to last the shift. I line them up (4-6 pieces, depending on dampness) like fallen dominoes and ignite one end. My budding room is 8' x 8' x 8'h. I do not seal my room and my blowers and fan schedules are not altered. I have my exhaust up high because co2 is heavier than normal air.

Do a little research. Your thinking carbon monoxide I am guessing. But in order to get c02 to the concentrations where it is dangerous for humans you would need a shit ton of tanks constantly leaking into your room or multiple c02 burners going constantly for quite a long time.

Burning charcoal to create c02 is far more dangerous than running a tank or propane burner will ever be.

i grow in my room and just set up the co2. i did the math in reference to the link you sent.

In my room which is 14' x 14' x 8' it will take a flow meter setting of 10 CFH running for 940 minutes (15 hours). At this time co2 levels should become lethal. Other factors such as central heating and air, windows, doors being open all lengthen this. At this long of run time the co2 tank should be depleted anyway.

After doing this, i think i will turn my flow meter setting down to around 5. This should give me more time to realize something is wrong....being that i sleep in the room.


I got the monitor set up and it seems to be working great. Even tho my room isnt 'fully sealed' it does hold co2 efficiently.

i picked up a Sentinel CHHC-1 controller...she handles humidity, co2, and temps. just learning how to work it now.
Big + rep for stepping up and doing that shit right. You will be VERY happy with the controller for sure. Since your now in the happy world of CO2 users producing FAT fucking buds, couple things to think about....

Research different co2 levels throughout the life cycle. You really don't need 1500 all the time and I have read several accounts of reduced potency with really high co2 in the last couple weeks. I'm not the weed god father or anything but have a pretty decent handle on botany, plant physiology, and hydroponics. This is generally my Co2 schedule...

Clones through 2 weeks... none.
first week in final home.. 700
second week...2nd - 5th of veg.. 1200 ppm, 90 degrees, 80% humidity
First- 3rd weeks of flower. 1500 ppm, 85-90 degrees, 60%
4-th- 6th weeks 1300 ppm, 80 degrees, the lowest humidty I can achieve from here through harvest.
7-harvest, 700-800 PPM, 40% or lower humidity.


I generally don't like super low humidity until I need it (to control molds). It is fairly stressful for plants to be hot AND dry..lots of vapor pressure deficit. Lower humidity has been proven to raise trichome and oil production (especially indicas). The lower the better.

Cheers :)

I would never waste my time using tanks of co2 gas. The advantage of using a charcoal co2 generator is that it will not cause water vapour to build up in the op and when arrainged properly will go out at the proper time. Approximately 2600 homes are destroyed in the US annually by gas explosions. $10 worth of charcoal will last a long time. It is easier, safer and cheaper than propane co2 generators. Before I'd use tanks of co2 or a propane generator I would set up back to back bud ops to supply the proper gases to my plants.

Right on thanks! Currently i am around week 4. Monitor is set to:

Turn co2 on if below 1400
Turn exhaust fans on if above 85 F

I do not have a humidity or heat device...do these values seem like a good start point?

Actual is:
1300-1500 Co2
77 F
46.5 RH

Basically the exhaust fans never come on because the temps never get that hot. If i turn the heater on to my house it will raise temps in the grow room..which might kick fans on a few times a day... I should try to get temps higher right? If im pumping co2, do i need fresh air exchange? I can interlock co2 and temps...when co2 comes on it will shut off exhaust fans and vice versa. I can also set them independently....but this way co2 is not wasted.
Has anyone used this particular model? Mine squeals like a computer thinking, i need to know if this is normal or not.

And these people aren't even growing pot. So if you don't understand co2, don't use it. Keep your exhaust vent tube as close to the ceiling as possible. Co2 is in fact heavier than normal air. Well at least you have some nice crystals happening in your pics. I always get good crystal in all my grows.

Could you point me to a manufacturer of a charcoal co2 generator or do I have to make one myself?

I use a small Hitachi barbecue. I have a metal cabinet I keep the barbecue in. I filter it and send it into my budding room. The cabinet that I am using is an electric smoker for smoking salmon. Someday when I get around to it I'm going to incorporate the element in the fish smoker so I don't have to be there at a specific time. Doing this type of stuff is what makes growing pot a real hands on experience. I even construct my own waterpumps.

I take it you have a carbon monoxide monitor? Do you have one that will follow the actual PPM or just an idiot buzzer when it gets too 'high'?

Smoldering charcoal eh? That is alotta incomplete combustion making all kinds of stuff. I suppose if you put it thru an AC filter first, it would remove alot of the VOC's and even CO's. But Im not sure I like the idea of stoners incomplete burning carbon to lift CO2.

Anyhow, thanks for the tip.

maybe he needs some better bud? heh...

aeviaanah how long does that early skunk take?
8-10 weeks...i havent selected a good trainwreck x earlyskunk yet, im still looking for the perfect pheno. one of two hermied on me, i put her outside...

Yeah, he typed like a prick and on top of that, he is completely wrong! The RH in my grow room today was around 15 percent. I guess the guy has never heard of a desert. But he sure likes to show his ass.

Look u think what you want. But I know humans on the planet earth and the ones that walk and talk a language you can understand. No one understands 6%-9% "RH" in a grow op no less.. You might want to try using that room to dry your clothes in. LOL.. U say I make myself look like an ass well go check out RH in the deserts of planet earth. None have 6% RH. LOL.. Douche.. It is dryer in the snow than the sand. Monkey. Don't ever try any thing that requires common knowledge! My Advice....... Use maybe some kerosene in a bucket and light that, lots of co2 I hear.......
