CO2 generation with a candle

[chuck estevez]

if the candle goes out from oxygen depletion, i will be surprised, even tho the CO2 levels are toxic to humans way before that happens. I am also concerned about the soot factor, looking for a plain old candle. I think the cylinder/regulator and controller is the way to go, i agree with you. Although that stuff has hydrocarbons (HC) in it too - just happens to be no spec for HC in any grade of CO2, including USP.

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is slightly less dense than air. It is toxic to humans when encountered in concentrations above about 35 ppm,


Carbon dioxide (chemical formula CO2) is a naturally occurring chemical compound composed of 2 oxygen atoms each covalently double bonded to a single carbonatom. It is a gas at standard temperature and pressure and exists in Earth's atmosphere in this state, as a trace gas at a concentration of 0.04 per cent (400 ppm) by volume, as of 2014.[1]

As part of the carbon cycle, plants, algae, and cyanobacteria use light energy to photosynthesize carbohydrate from carbon dioxide and water, with oxygen produced as a waste product.[2] However, photosynthesis cannot occur in darkness and at night some carbon dioxide is produced by plants during respiration.[3] It is produced during the respiration of all other aerobic organisms and is exhaled in the breath of air-breathing land animals, including humans. Carbon dioxide is produced during the processes of decay of organic materials and the fermentation of sugars in beer and winemaking. It is produced by combustion of wood, carbohydrates and major carbon- andhydrocarbon-rich fossil fuels such as coal, peat, petroleum and natural gas. It is emitted from volcanoes, hot springs and geysers and is freed from carbonate rocks bydissolution in water and acids. CO2 is found in lakes, at depth under the sea and commingled with oil and gas deposits.[4]

The environmental effects of carbon dioxide are of significant interest. Atmospheric carbon dioxide is the primary source of carbon in life on Earth and its concentration in Earth's pre-industrial atmosphere since late in the Precambrian eon was regulated by photosynthetic organisms. Carbon dioxide is an important greenhouse gas and burning of carbon-based fuels since the industrial revolution has rapidly increased its concentration in the atmosphere, leading to global warming. It is also a major source of ocean acidification since it dissolves in water to form carbonic acid.[5]

i would think u would get more from sugar and yeast. connect the exhaust made of a fish tank line thru to the back of an osc. fan to blow it over ur girls.

at a certain point though it stops being cost effective, the co2 tank would probably be the best bet in the long run though i personally really like the sugar and yeast method for small compact spaces, but it ends up becoming another variable you feel like you should keep up with.

thanks chuck, what is the 'proper equipment'? a co2 tank with regulator and flow meter? My room is air tight, no outside vents or intakes for that matter, just a door

CH, I dont know if UB still sells 'em, but i have a feeling i wont be buying, just sayin'

Unless you can separate the systems, you will overheat your growing area by using generators. Only way out is tanks, and they are costly and make ears go up. Stay simple, use good lights and wait. CO2 is not for your average grower as it causes it's own problems. Been there, said fuck it, not worth it. Peace out

that's what i didn't like about the yeast method, worked for a few days then needed to restart, couldn't figure out a way to keep it going by removing some spent product and adding fresh on a regular basis. I am still mulling over in my head a way to add a little water/sugar at a time while at the same time removing some of the brew at the same rate, but only using gravity.

I tried this shit years ago............If you want to go this route I suggest small candles(tealights/4 hr burn) with a short burn time so it runs only during lights on; no wasted $$. 100 pack of tealights at ikea is $4, can't beat that for 100 day supply ....lol

https://www.rollitup.org/t/testing-hans-panel-56watt-cree-xp-e-lumiled-rebel-power-lets-talk-efficiency.531652/ using a ppm meter is highly suggested and the usual safety precautions obviously.

good luck

i run co2, and i don't have a meter. my room is fairly small, and sealed. my light is vented out of the room, and i use a small fan at floor level to force co2 back up. my reg. is plugged into my timers repeat cycle timer. it all works well, and is not all that expensive. some of the co2 equip. can get pricey, but i feel is unnecessary, unless you have a fairly large grow space. burning candles/yeast etc. imo, is a waste of time. if you get a cheap syringe type co2 tester, and do a before and after test, you'll see little to no diff. in co2 levels. some will swear it works, but it's in their minds. if you check the levels, you'll see for yourself...

Hydro shop and online you can get a bag of fungus that raises co2 in room about 300 to 500 ppm over what's natualy there. Last a month or more. Small room one is $12.Produces when lights on, stops at lights out.

that sounds awesome, do you know the name of the fungus? and correct me if im wrong but dont they take up co2 during lights out as well? i think ive heard they do it more during lights on but it could be the other way around.

there are different sized bags, but they are really only beneficial for small cabinet type grows, 3x3 or so. your cab will need to be sealed. if you're in a say 10x10 room......

3x3 fits me to a Tee, 'that sounds awesome, do you know the name of the fungus?'
