I am doing an experiment with my indoor plants right now by raising the Co2 levels and seeing how it effects the plants growth I have heard that Co2 can make plants grow twice as fast when the atmosphere is high in Co2 I dont know how true it is but it sounds logical.
I hazve 15 plants growing in my empty fishtank with 2 Growlights which are doing the job quite well. It sounds logical that candles burn oxygen and leave Co2 and other gases which circulate inside the fish tank and when the temp goes too high I turn on the fans which dry the air up a bit and leave the leaves looking green and healthy eccept muy leaves were burnt because of over fertilization or a very alkaline Ph but I have only started to use the candle method and over a period of 6 hrs the humidity has gone up and the leaves look alot healthier and greener.
Any other suggestions on my experiment?
Thanks
P.s Aussi weed is top stuff especially the out door stuff.

I prefer to use those oil buring 'lamps'. I have had many a candle eat its self the melted wax leaks out and the flame gets really big and just keeps melting more wax that leak onto the floor/holder. But I think the idea is sound. I haven't had the spare cash to get a co2 gauge to check things out but I don't think too much is bad so...

besides the oil is much cheaper

Im using those incents candles where they dont leak, like they have these little cups around them. Wouldnt the oil ffumes damage the quality of the smok?

I don't know what the oil fumes do, but what about the incents smoke damaging the plant. Because i heard that smoke can block up the poors of the flowers.

I reckon that using oil burning lamps would be good because it would create CO2 and provide humidity for the plant (which is optimal for the plant to grow in).

However, I don't like having a flame in my grow room cause just imagine if a dry leaf fell down onto the flame and made the all the plants go up in flames!

a good oil lamp produces very little (no) smoke and I'll tell you I can notice the diffrence visually from one night of growth with out campared to with out. There really isn't any chance of a leaf catching fire with my set up and if it did the worst that would happen is that the carpet would melt a bit. How long are you burning your candle for? At one point I figured (using molar calculations) that it would take about 2 hours of candel burning to produce enough co2 to bring it to optimal co2 levels however I need a good bit of ventalation to keep tempatures down (around 80-85F) so I just leave the lamp buring while I am at home and hope I don't die of co2 poisoning.

You're not producing Co2 with candles! hahaha

CO (Carbon Monoxide) is produced with fire that emits a YELLOW flame. Such as your candle...

CO2 (Carbon Dioxide) is produced with fire that emits a blue flame. Such as a propane stove, propane lantern, or burning natural gas.

Here's an exerpt from a web artical on this subject.

"1. BURNING HYDROCARBON FUELS:

This has been the most common method of CO2 enrichment for many years. A number of commercial growers and greenhouses use it in their larger structures. The most common fuels are propane, butane, alcohol and natural gas. Any of these fuels that burn with a blue, white or colorless flame will produce carbon dioxide, which is beneficial. If a red, orange or yellow flame is present, carbon monoxide is being generated due to incomplete combustion. Carbon monoxide is deadly to both plants and people in any but the smallest quantities. Fuels containing sulfur or sulfur compounds should not be used, as they produce by-products which are harmful."

So.... you're lucky your plants are still alive.... now blow that candle out. (did you make a wish?)

Candles--> <-- Plants.... any questions?

well it sounds intresting but they are missing something because I have closed my closet door and left an oil lamp burning with out a fan blowing and seen increased growth rates over leaving the door wide open with a fan blowing. I would guess that even though an orange flame is producing co it must also be producing co2 and the ratio is enough to increased growth. As soon as I get my computer (2 weeks til I get it who knows how long it will take for me to hook up) I will post some pictures of growth with and without however I only have one grow room so I am going to have to do one than the other and not at the same time for a direct comparison. Any suggestions for this comparison would be appreciated.

Hi there! im perticularly interested in this thread soley because of the conversation about differant gases being emitted by differant fuel sources....ok im a heating and air conditiong technician by profession and i work on/repair/and tuneup every kind of heater you can think of...Natural gas/Fuel oil/and Lp gas as well... now the truth is this...yes it is true natural gas and lp both burn alot "cleaner" what i mean by cleaner is they are more "efficiently" burned thus meaning they combust alot more efficiently. it is also true that natural gas and lp give off less carbon monoxide, and more co2(in optimal burning situations, (if your element whether it be spark or hot ignition igniters or other things are preventing an unefficient burn then natural and lp have a potential to burn unefficiently as well)but generally speaking natural gas and lp burn better, or cleaner. Oil is mainly used because it produces more btu's per gallon then natural or lp does, it does produce more harmful gases like carbon monoxide in a larger form, but puts off more heat per amount(though its messier). An "oil Burner" can be made to run extremely efficiently and to burn pretty cleanly(by a licensed service technician such as me, who knows what their doing)then you could minimize carbon monoxide..just remember that the most efficient oil burners are only 85 percent efficient and lp and natural are little higher ...its just efficiency vs cleanliess vs btu's vs prices of fuels .....but my opinion would be go with the natural gas,or lp it burns alot more effieciently and are a little safer!(and remember Carbon Monoxide can kill by entering your bloodstream and DENYING oxygen to your blood!!) BE careful with whatever you do please...hope some of this helps, and if not maybe my rambling while im high as a kite will give you a lil info you can use in other areas lol!!

p.s. insanek9 is absolutely right that the color spectrum of the flame is a sure sign of carbon monoxide being emitted or not...e.x. new ideas on fuels for cars is natral gas(because its veryyyyy abundant and it burns more effieciently and "cleaner" (little or no MONOXIDE") internal combustion engines running on gasoliine are only about 35% effiecient the rest is waste!they also give off a substantial amount of monoxide! BUT the power or btu's it produces is more then Natural gases! just a little bit of facts i thought id throw into the air!!!!peace.

You know maybe I have given the wrong idea about what i'm using. I have a glass orb, 3" round, that holds liquid parafin (24$ per gallon specificly for the lamp), I checked. The wick is a synthetic strand material that is suppose to burn forever. I am assuming since it was meant to be burned in the house that there is little risk of co build up even when I leave it burning for 8 hours straight. So what do the people have to say now? Please let me know if it's more than the weed making it hard for me to get up in the mornings.
