Yeast/Sugar/Water mixture for CO2

[kissthesky]

Anyone know the ratio of brewers yeast/sugar/water to produce CO2? (Somewhere online I read 15 mL yeast w/600g sugar. But that seems like a lot of sugar (21 oz.) and very little yeast (15 mL = 0.03 pint).)
I have a small grow and a little ventilation so I wanted to give this a try.

what worked great for me is redmans yeast(in the baking isle)fill a gallon jug a little less than half full of warm water pour in 2.5-3 cups of sugar shake till all suger i gone add about 1teaspoon(tsp)of yeast shake about 1-2min poke a few holes in the cap shake every few days will last about 2-3weeks has worked well for me turn fan off for a few hours or it will blow out the co2 distill the mixture to make some strong liquer good luck man love your plants pos. energy equals happy potent buds
