I don't know what it will produce but I used that mix in a bottle and put it near the closet with a fan blowing it in, And the plants close to the airflow had browinsh leaves the next morning !!
I just have it in the room about 4 feet from the closet intake now.
 
I would like to know the average CO2 produced as well! I have two 20oz bottles with a cup of sugar and a yeast pack, and a 2-liter with the 2cup to 1pack ratio in my closet and have very healthy plants. Use a nail to poke a hole in the lids, leave the lids on from then on! It will help cut back with the mess and when you shake up the solutions you can just put your finger over the hole. Both 20oz bottles are positioned directly under the center mass of five plants and I've had no adverse reactions. I do have to computer fans running over the plants, and one 12" fan ventilating the air and heat out, which is a factor I suppose.

You should have this placed above your plants, as Co2 is heavier than air, therefore will fall. Is the vent fan at the top or bottom? I would hate to see you waste your time making these contraptions and then blowing any Co2 you may have created straight out of your room.

If you really want to know how much Co2 you're creating, buy one of these: http://www.co2meter.com/ Shit ain't free, but it seems like a waste of time to build little devices and have no way of knowing how much (if any) benefit you are receiving from them.

Glad to be of assistance. I'm not the smartest guy on the block, but the sun even shines on a dogs ass some days...or something like that.
 
I use that same method. 20 oz bottle cup of sugar and yeast. It creates enough co2 to keep my meter reading 34 ppm for the first week but it slowly drops off over time. Little trick with this the more sugar you use the longer it produces co2. The more yeast you use the faster it creates co2. Iv used this method for fish tanks. And mj plants. Works well. Oh and keep in mind these are my numbers in my grow room. Yours very well could differ due to a lot of factors. Room size. Amount of plants. Airflow. Etc etc.

Thanks for the help, my area is small, so this should suffice

Ppm stands for parts per million. A TDS meter measures the parts per million of, Total Dissolved Solids. Co is not a solid and cannot it will not affect your reading. Not that it really maters because what exactly is it that u believe that thing does for you anyway
