Sugar and Yeast vs. Baking Soda and Vinegar

hi all,

i am currently in the process of determining the best way to produce co2 without a tank and regulator, right now i have bottles set up with baking soda/warm vinegar....baking soda/cold vinegar.....sugar/yeast/warm water....and suagr and yeast/cold water....and a retrofit pressure guage on each, as of now the yeast/warm is at 6 psi w, the yeast/cold at ~4, vinegar/warm at 8.5 and vinegar/cold at ~8 all with 12 floz total mixture in each, going to experiment with ratios soon, will keep this updated if all goes well

Did you ever figure out what the best result was?

Thanx keep us posted if it work good ill try it
