I have a few jugs of sugar, water and yeast.

It will produce carbon-dioxide gas, ammonia gas, and water. It's a fast reaction.
I Would not use it. I wouldn't even use baking soda and vinegar. It's to fast of a reaction. Your plants never get the exposure time they need to absorb the extra CO2.
Yeast and sugar is IMO the best poor mans CO2 set-up. It's safe, it will produce CO2 for a week or so. (Use Lager yeast. It makes more CO2 than wine yeast.) If you do use yeast and sugar make sure to make a bubble counter out of a pop bottle and cooking oil. The counter will clean the CO2 gas, the oil is viscous making it easy to see how many bubbles of CO2 gas. If your mathematically inclined you can calculate the volume if gas your producing.

Must be very fast because I've seen that recipe - ammonia, baking soda, and water - recommended for cleaning. Just mix, shake, cap, and store. Well, if you cap anything that is actually generating CO2 over time (like yeast and sugar), it will explode!

champagne yeast and sugar works great. i use a 5 gallon bucket with the pump from a co2 boost bucket that penetrates the lid. i use an air stone to keep the mix agitated and run the pump lines to my oscillating fans and clip them on. usually only use in weeks 4-7 as the yeast isnt active very long.

I use a setup like this, whats that oil filter you be talin about? I wonder if I could adapt it to my setup

The middle bottle acts as a filter. In this diagram (CO2 for planted aquariums), water is used. You could use oil I guess - veg or mineral, not motor. Note that the CO2 from the yeast bottle flows in through a tube submerged in the filter (oil or water). The output of this is up at the cap and not in the oil. The "check valve" is not needed since you 're releasing the CO2 into the air and not underwater.
