CO2 from candles?

Hey Topfuel.
Would you be so kind as to post a better pic and description of your co2 bubbler?. I'd like to try an experiment to see if an increase will change the outcome. Also, do you have a source for an inexpensive co2 meter? I've looked and damn if the ones I've seen aren't about $1700.00 a bit out of my price range.
Thanks

Candles and CO2=

100% pure paraffin wax is basically CH2. The O2 combines with the C to produce CO (carbon monoxide) and CO2 and with the H's to produce H2O. Therefore the candle is using more O2 than it is creating CO2. This is true of other waxes as well but the other waxes have even more elements to combine with the O2.

But that's good isn't it? Plants don't like o2 very much, thay get all thay need from photosynthesis. And if you have enough oxygen in the air then no carbon monoxide is produced. Carbon monoxide is produced when not enough oxygen is available, it is not toxic to plants anyway because they don't have blood so have no heamoglobin for the co to bind with.

I've designed a system, had a bunch of help from a biochemist/ computer guru*s8 seriously though, this dude knows his stuff, We're working on a system controlled by 'puter with as much included as possible. as much for information as too keep it as a working system as I don't venture far from home if you know what I mean.

In creased heat.. ppm becomes less
I anit stopping you dude give it a go.... report back- get some hydro foam for co2 testing ( i think its that ) to test your ppm. LOL

In order to produce co2 there needs to be a fuel source, in this case it's wax, the amount of co2 being produce will be minimal, you need a fast burning fuel source in order to get the co2 levels you need. And that source should be a clean burning one, like propane or natural gas... And even then there is a decent amount of carbonmonoxide being put out...

Candles... Hahaha... That's like using a single x-mas light to try to grow.

Would you explain Hydro foam? I need to check my co2 and while there are inexpensive methods..they 're a bitch to set up and time consuming, and*shudder* higher math. You know, boil the water..bubble room air through it, check the ph..if you have a digital ph meter. So, where can hydro foam be gotten? Thanks

It would put out some co2 though, the yeast method is obviously better, I'm not saying candles are a good idea. I'm just saying they would work, sort of. Carbon monoxide doesn't harm plants by the way, and it quickly oxidises to form co2 so it doesn't matter how much co you get from your fuel because it ends up as co2 in the end.

I'm trying to figure out the amount of co2 produced from a given quantity of either chalk or baking soda, or what ever source. After that's determined then I can design an auto dispensing system. I'm loath to use natural gas as I really don't want an open flame in case it goes out. I guess I'll install an extra auto shut off valve.*shrug* It's all still up in the air so too speak*lol*

Thanks, I couldn't figure out what hydro foam is.*l* I'm trying to figure out a system that doesn't use flame but household chemicals..doesn't look like it will work for my size room. That's the lowest price I've seen for the co2 kit. Thanks for that. When I'm somewhat richer than I am now, I'll get the various controllers. I've been designing a puter based system , not PC more as an exercise for the brain, unless it's inexpensively. I will be adding co2, but not to the whole room. I'll be piping it to the bottom of the plants. Thanks again for the info.
