I have a valve to release the CO2 in a slow fashion so when I give the 2L bottle a shake I can see the bottle's sides expand under the pressure...

It has had an amazing effect on my grow It is so easy to set up it's crazy not to use the simple system.

I will be changing the yeast every 5 days or less. So I can do a whole bloom with 5 packets or so... it's cheap as chips so why not invest in it !

But really, there is a lot of CO2 coming out of that simple 2L bottle... More than you can imagine !

Do you have a picture of your co2 set up by any chance? Im making mine the same way except I have 6 1 gallon containers which is one container per 2 plants. It has seemed to make a difference. My question is do I have enough yeast added? I wen with 10 tbsp of sugar, filled with water to about 3/4 full, and added one tbsp of turbo yeart per container. Also I have drilled a 3/8 hole in each cap on the container and inserted a hose about 5 inches long for venting the co2 out
