The cheapest CO2 is simple... fresh air from outside... Baking soda and strong vinegar works pretty good too, and is cheap... Sugar is pretty expensive for the amount of co2 you get. You also get alcohol evaporating into the air, which isn't good for the plants.
Cheapest co2 would be to burn something that produces a clean burn, like propane. But only do that if you have sufficient cooling. You only need a small amount of co2, so keep it small.
When the plant stores energy, it needs co2. But when the plant uses energy, it needs oxygen. So don't produce so much co2 that you starve the plant of o2.
But that gets you back to fresh air is the best thing.

There used to be a growfaq on this. Nic eof you to share.
1. Make sure you don't over do it, because you can burn your plants with too high a concentration of co2.
2. You want humidity at 40%, and no more than 505 in flower. n Higher in Veg.
3. Do not try to use a burnable gas. Although we use co2 generators/heaters in a commercial greenhouse; I really do not think this is a good idea for a grow room unless you have a very big room or greenhouse setup.
