CO2 To Combat the Heat??

This may seem like a stupid question, but i've been battling temps for the last week, leaving me at around an average of 85F. Which is too high for comfort, and since the summer has barely begun, it's only gonna get worse. Tell me, if I manage to up the CO2 in the room, can I simply let it remain that hot due to the increased co2 level?
There are simple CO2 DIY designs I can easily make. Cooling a hot room cheaply isn't NEARLY as easy.
Is this a viable option, or...?
Any suggestions are welcome.
But before someone said "Get an A/C" "Get a ventilation intake"

I'm growing in soil, have 5 plants under 17 26W CFL's, they'll start their first 2 weeks of flower under them and then go under a 400W HPS. Which will only increase the heat even further, making a Co2 setup almost a necessity. Also, are there any precautions I need to take regarding the use of Co2? I know they can explode if not vented properly and if mixed in the wrong measurements. But what about breathing it? Would I need to seal off the room so it doesn't leak out? Or will the standard ventilation of a room be enough (IE; Ceiling Fan, Osc fan, open door, a/c vent from central air conditioning.) And the ROOM itself is 10 ft, by 11½ feet.

Too much info? Maybe...but many times when I question is asked, the answer is just out of reach due to a lack of info.
Thanks in advance, +rep and likes for helpful answers!!! bongsmilie

If it's 85* now using just CFL's, what do you think is going to happen when you spark that 400w?

It will be too hot even with the C02.

I really don't see any way around not improving your ventilation to deal with this, CO2 or not.

Is this a viable option, or...? You would need at least 800 to 1100 PPM of Co2 to make a difference and I don't think any of the DIY systems can produce this amount.
Any suggestions are welcome. Fill some 2 liter pop bottles with water and freeze them, put one in a bucket of water with a small fan blowing gently blowing over the water surface this will drop the temps. Just keep extra frozen bottles in the freezer.

None you should be concerned with if your making a DIY system. It takes a ton of Co2 to become toxic. I know they can explode if not vented properly and if mixed in the wrong measurements. Yes be careful, they only explode if they are not vented. But what about breathing it? No issues. Would I need to seal off the room so it doesn't leak out? YES Or will the standard ventilation of a room be enough (IE; Ceiling Fan, Osc fan, open door, a/c vent from central air conditioning.) And the ROOM itself is 10 ft, by 11½ feet. Your room is 115 sq. feet and you are not going to make a DIY Co2 maker big enough for this room.

Just go with the frozen bottles.

Thanks everyone so far. I've been under the impression that if you can use Co2, you can keep your temps around 90 or so. which would be a typical temp in there once the temp outside kicks up, the problem is that it's warm out now, but not warm enough for the ac to turn on yet. Once it starts turning on, it won't be so bad. But as it stands, NO A/C yet, and I think once the temps outside go up, i'll be able to keep the room cooler. I just feel if I add Co2, it will make it so even if I can't have complete control of the temps in there, a few degrees too hot wouldn't be an issue. I'm going to seriously consider the frozen bottle idea tho.

Indeed. 85 is a pretty average temp i'm having to deal with. So it's not unreasonable to think that if I can give each plant their own DIY Co2 Generator releasing underneath them to allow for maximum usage. I should be able to tolerate the higher temps. I know I won't be able to use the Co2 to it's maximum potential since the room is large and I won't be able to allow it to accumulate to sufficient density. But since i'm battling the heat anyway, I figure what could it hurt to add the DIY Co2 to help?

No, CO2 is not flammable and will not explode in any circumstances. Why do you think thy fill fire extinguishers with CO2?


Maybe you meant the professional combustion CO2 generators could explode, in which case you would be right...

No No, not like...FIRE explode, like, the jug may explode yeast all over if put under excessive pressure. Which simple means your DIY design (or your execution of it's creation) was flawed. It's simply something to consider of what happens when a DIY Co2 device goes wrong...

However I do appreciate the input.

yes co2 allows warmer growing temps but heres the catch, co2 is the number one greenhouse gas, which means that your room will heat up a lot after enrichment. co2 absorbs infrared heat light causing the molecules to vibrate, which creates warmer air that acts as a blanket.

^this^.

if you're already having temp issues, AND you're plugging in a WAAAY hotter light, you're going to need a more realistic longterm solution anyway.

Not long term, by the time the HPS is running, the A/C will be also. So that will balance out. And it's not as if i'm just running a couple CFL's and im having a heat problem with it, i'm running 17 CFL's, and having a problem :-P
But I think if I use Co2, get my exhaust fan running (part of the carbon filter) and maybe that frozen water bottles in the cooler with a fan blowing out cold air idea, I think i'll be set. Shouldn't need much more then that to get me through the next 3 months at most. Once this grow is done, I'm gonna pack it in til i'm growing in my own place. Roommates can be a pain in the ass! ;-)

not to mention CO2 doesn't do anything with a 400w HPS. It only works once you have all other factors maxed out and a lot of LIGHT.
