Co2

OK I have an idea for a CO2 maker, but need someone's input from some experienced people.

OK make the traditional 2 liter bottle mix with yeats water and sugar. Drill 2 holes in it and put plastic air line hoses in the holes. Have the exit line go to the plants and have the other tube hooked up to an air pump. The intake tube hooked up the the air pump would have to purposes. 1 make bubles in the mix which would stir it so you would have to shake it up every couple hours, and 2 create an air flow out the exit tube to the plants.

Would this work or would the oxygen going into the bottle mess things up?

It sounds like a good idea to me, personally I'd just use a very weak air pump that slowly cycles the air through but it sounds great, I think I may try this

cool. Yah I have a bunch left over from my fresh water fish tank days. I have one that I can adjust the output on.
