When you mix baking soda and vinegar it bubbles up and produces co2, Ive been doing this quite a while,, but I wanna know if anyone else does? Also I was wondering if anyone with a co2 monitor (or any reuseable co2 measurer) would tell me if this puts out a lot of co2. Im pretty sure it puts a lot out, cause even my friend said that the room smelled weird, and it wasnt just vinegar, and Ive seen improvement on the days where I do it (usually several times a day). Let me hear what ya got to say about this people. The way I do it is cut the upper part off a milk jug and put a small cup or small small dish inside the jug and fill the small dish with baking soda, and also fill the bottom around it with baking soda, then I pour a bit at a time (be careful it doesnt fizz up and out) in the lill dish and itll produce co2. Very cost effective too.

I have generated C02 by mixing water, sugar yeast and a small amount of urine in a 3 gallon demijohn You can use one of those stoppers with a hole in it and a piece of flex tube to ditribute the gas where you want it. It should give a slower moor steady flow than the volitile mixture of vinegar and baking soda. Dry ice is another source. Dry ice is cheap and can be kept in a cooler for slow evaperation, again using a tupe for distrobution. I imagine a 5lb block maky last several days. I think some welding suppliers can get dry ice. You can say you want it for shipping specimins or food.

I believe the gas is hevier than normal air. something to consider when placing the tube. I may be wrong though, can anyone verify?

I have also heard about the yeast and sugur water, my question would be...what kind of yeast there are different types( beer, bread)::

By the time you go through all that vinegar and baking soda, it would end up costing more than 12gram CO2's. You can buy a pack of 25 of these at walmart for 10 bucks, and I forgot who it was, but they use a bike tire filler that uses 12gram CO2's, he said they are about 15 bucks. Then again, if you paintball you could use the 12oz or 20oz tanks which is even more cost efficient because it costs about $3.50 to fill up a 20oz tank.

I paintball and get free CO2 refills (work at a field), so I plan on using two of my 20 oz tanks. I can turn the valve on a bit and have a slow constant leak for a while, and 20 oz is a lot of CO2

wine yeast works best, when I fget this one file again ill post the 2 brands that i read

yup, CO2 is heavier than air for the most part. Im gonna be trying the dry ice in the cooler thing.

I also have a paintball gun, have 2 20oz tanks, where do I get something to let the co2 out, do i do it a couple times a day or week, do I leave it on till it's empty sounds like an easy way for me to add co2 to my room

tank 100 reg. 60 tank refill 13 timmmer 25. Only works for a 10x12x8 ft room for 40 days. Hum almost as expensive as the cheap way. hum. Say when you inject the measuring samples are 8 buck each. Also the grow space must be a tight as a condom. Any leaks and its a dumb guess. Also you must dump the air out at night. YOU all know that, and at 3000 its toxis to the plant you know that. hum YOU all might want to use the free stuff in the air. 300 ppm so if you changed the air out often it might be better 1 free co2 2, air movement, 3 cooler temps. Hum its free, does not metering and cost almost nothing.

Phatfarmer, you need to install an on/off valve on your tank, they don't cost that much at all, and will save you a bit of CO2/Orings
