How can i get co2 (besides yeast)

[tkjoe]

it kinda smells like sweet bread dough (go figure lol) but it's really faint, nothing like vinegar. I hear that if you use the same mix for too long (over a month) they can develop some nasty smelling mold though

SO just change the mix once a week or every 2 weeks?

I change my bottles every 2-2 1/2 weeks

awesome thanks man!! check out my grow journal! in my signature. ill add a bottle tomorro

why not just use the yeast method. and also if you do use co2 do it between the hours of 5a.m and 7a.m that way your plant are more suseptable to take in co2 and other trace element in the air.

Please explain why they are more suseptable at those times?

I know that co2 is only beneficial during daylight hours when the photosynthesis process is taking place. So I'm guessing what that guy meant is that during the first few hours of daylight is when the plant processes the most energy. So if you're growing indoors, those times are not set, it's just the first few hours after your lights come on.

The yeast method is the cheapest most efficiant way my room is 5x7x6 I use two 5gal buckets 10 pounds sugar each bucket changing one every week cost me under 5 bucks a week and I use a lot I have a tank controller moniter coming this week before I take out the buckets I'm goin to put in the monitor and see what its at in my air tight room

Yip thats dam right! We make there time in there world,its fun being god!

Your grow room sounds pretty big. I have a 8 x 12 flower room that holds 160 plants and I run CO2 in there from my natural gas hot water heater (my flower rooms in the garage) It cost me a total of less than 80.00 bucks to build and install and the co2 is free. I posted a thread on it in the DIY sub forum. I don't know if this will suit your needs but it did mine and since I installed it my plants have taken off like bats outta hell.

good luck on your grow

the reason why i dont want to do yeast is because i would need like 8 gallons of mix and my growroom is gonna be loaded.

I ve played with c02 alot. if you grow room is big, i would say save your money and do it right the frist time.

Get a controller, cool tubes, c02 tank and reg or a genater. and look at making your room a c.a.g.e

that is an awesome idea, props man. do you regulate the flow in any way?

I was just making a suggestion to the brother. I'd go the route of tank/generator,controller ect....if I had to, but this setup works very well for me . It may or may not work for others. And just because I didn't spend hundreds and hundreds of dollars on a store bought professional CO2 setup does not mean I didn't do it right the first time.

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.
Most commercial CO2 generators that burn these fuels are too large for small greenhouse or indoor grow room applications. Some small ones are avai fable or a Coleman lantern, bunsen burner or small gas stove can be used. All of these CO2 generators produce heat as a by-product of CO2 generation, which is rarely needed in a controlled environment grow room but may prove beneficial in winter growing and cool area greenhouses.
The rate of CO2 production is controlled by the rate at which fuel is being burned. In a gas burning CO2 generator using propane, butane or natural gas, one pound of fuel produces approximately 3 pounds of carbon dioxide gas and about 1.5 pounds of water vapor. Approximately 22,000 BTUs of heat is also added. These figures can vary if other fuels are used.
To relate this to our standard example in an 8' X 8' X 8' growing area, if you used ethyl or methyl alcohol in a gas lamp or burner at the rate of 1.3 oz. per day, we would enhance the atmospheric concentration of CO2 to 1300 PPM if the room was completely sealed.
An enrichment standard of 1300 PPM was chosen as it is assumed that 1500 PPM is ideal, and that the plants will deplete the available CO2 supply by 100 PPM per hour. Remember, the normal atmosphere contains 300 PPM of CO2. A 100% air exchange (leakage) every two hours is assumed to be the average air exchange rate in most grow rooms and tight greenhouses. If many cracks and leaks are present, this exchange rate will increase significantly, but added CO2 (above 300 PPM) will also be lost. If a vent fan is in use, disregard CO2 enrichment, as it will be blown out as fast as it is generated.

lol your post was not up at the time i started to type mine,i am a slow typer.
so dont get bent out of shape

and yes i like the gas hot water co2 ducting,
here in nz that type of hot water heater is not very common.

Nz ?

you could find a small portable stove or bunsen burner anything that runs on propane (also get a flam guard like the ones used in lanterns) run it on low you may have to buy a CO2 ppm meter to find the right rang 800-1200 dont go over 1500 FYI you could also use co2 enrichment to kill bugs increas ppm to over 2000 for like 1 hour i think
