How Much CO2 in an Exhale?

I have absolutely no info on this and was simply brainstorming during my last bong session. I was wondering how much CO2 might be exhaled in a breath. Would it be possible for a tiny grow room (3-6sq/ft) to take advantage from blowing up party balloons and puncturing a tiny pin hole in them to slowly release the CO2. A childrens magic trick to do this without popping the balloon is to place 2 pieces of scotch tape in a cross on the skin of the balloon and press the pin through the intersection.
This would be total redneck engineering but just wondering

If i can remember correctly from my memory i remember reading that exhaled air has something like 17% carbon dioxide? or somethin and i think your body doesnt use somethin like 4% of oxygen

thats a good idea with the ballons though. why not get a co2 tank and fill up the ballons and then use that method. or just get some yeast and sugar, thats what i did.

yeah i keep reading about the yeast method and wonder why nobody is trying to capture the gas instead of just letting it seep into the room. Is there something in the balloon material or the chemical make-up of the gas that wont allow it to be captured this way. Just trying to think outside the box a little. Of course this can only be concidered in the smallest of grow rooms

The air we inhale has only 23%-24% Oxygen and if was any higher we would be flammable.

imagine if air was flamable... that would be nuts... and suck... we would all be dead... light a match and the whole everything burns

crazy hun Oxygen being an accelerant, poor astronauts didn't think about it in the Apollo missions

Thats an ingenious idea - and there is a way for you to fill balloons with nearly 100% carbon dioxide. All you have to do is inhale deeply and hold your breath. The longer you hold it, the more oxygen is absorbed and the more CO2 replaced. Holding your breath for a good 30 seconds or so would do the trick. After the balloon is full, place a piece of scotch tape on the bottom of the ballon and pucture at the center of it - it will help the rubber hold its shape and not rip at the pucture location. If you filled 5 or 6 a day I'm sure it would work.

thats what my redneck logic is telling me hahaha. Im sure this is only a small help in a very small room, but it has to be better than none at all.
Is it better to do this during veg or flower or both?

also by room i mean closet or box

I can tell you this and i can confirm it from my greenair produce controller. I breath into my co2 sensor and i got a reading of 5000ppm of co2!!!!!!!!!!!!!!!!

Thats freaking alot dude! Plants only need from 1300-1500 at max point of flowering. I talked to my hydro guy and he told me that if u are in a inclose space depending on the room size lets say 10x10 he said if u step in your raise the co2 ppm to 500-800. So i've said this before in many post i dont know how many tried to avoid my suggestions but talk to your plants or breath onto it more often! thats a INJECTION of co2 for them. 5000ppm!!!!!!!!!!!

lol

I'd say just use the yeast method. Turn off your exhaust fer a half hour a day, and during that time place the yeast n' sugar inside the box. Remove when the air comes back on.

i keep my bottles in at all times u just turn off the exhaust when i shake them. if u have an oscillating fan keep it going because c02 is heavier than air so the fan will keep it up off the floor. c02 is good for both flower and veg but it will be most beneficial in flower.

Youd be surprised -

A lot of the yeast methods look like they produce just as much as a few balloons full of 60-70% CO2.

I think it would be a big help, especially if you keep the closet door shut.

in just a few days i will be starting my clones. My room runs Very constant temp/humidity so maybe i'll try the first batch without balloons, then the second with. I'll keep everything the same including clones from the same mother and tests to see what happens. Look for some results in say about 2-3 months. hahaha

i will test the ppm of a yeast method towards a popping ballon for you guys when i get the chance.

you can capture it but i think that some molecules are small enough that they diffuse out of the balloon fairly quickly. think about a helium balloon. you fill it up with helium but it doesnt stay full. after a few days it is all limp and scrawny looking. some gases and compounds undergo this diffusion more quickly than others. i think it has to do with the molecule size. im not sure how long a normal latex balloon would hold co2 though. you could probably find something about this by just googling or something. interesting idea though. storing your exhaled breath. hahah.

Great idea, i'm using candles (ALWAYS SUPERVISED), bottled co2 gas is the way to go, but to much hassle to fill in UK cause its a shithole

Ive been using bottles of yeast and sugar for years,i just place them under the grow tables,fan mixes the co2 into the air just fine

I check on my plant probably 3098520358 times a day and everytime i go too look at it, i spend at least 5mins blowing air on it, or breathing on it.
My plant seems to be doing fine.


Heres the thing.

If you wanna blow up some balloons and let the air seep out into your room, it is definetly NOT going to hurt the plants.
It may or may not help them, but it wont hurt them.

If you want too, and it seems like a good idea for you...just do it.
