That is a easy way to make CO2. Basically anything with yeast and sugar (toast helps).

I have a 2 liter soda bottle that I fill up to where it curves inwards with warm water, dissolve a cup of sugar in it, wait for it to cool down to room temp, then put some crumpled up burnt toast (half a slice or so) and then I put 1/2 tablespoon of yeast in there. Then I got the cap and made a small hole with a knife in the top so I could barely get some 1/4" aquarium tubing in, put some sealent on it. Measure out how much tubing you want, cut it, then take the tube outside, light then end you just cut on fire for a few seconds then use some pliers to clamp down the molten plastic to create a end cap. Then make holes the size of the end of a pen where the tube goes over each plant and screw it all together and you are done!

Nice work Hash ! you described the easy co2 tank, it works well for me. Its good to shake the shit out of the bottle everytime you go past it. Keeps the yeast active and give the plant even boost of co2

Do you f*%! around w/ a monitor if yer to go at on the fast, cheap simple route? Or does a 2 liter bottle have an ideal sq footage it'll supply co2 for?

Btw I make bread and beer, and am thinking of piping co2 into my grw room from that. Am I going to end up with bread bud? mmm pot beer...

Seriously tho, sterility issues perhsps?

just sit in your grow room all day taking deep breaths.

with the sugar, yeast method i used 2 cups of sugar and 1/2 teasepoon of yeast in a 2 liter bottle is that okay? also instead of drilling a whole in the cap and puting my tubing their, i drilledto holes right underneath the cap and put two different tubes threw it will the co2 come out okay wiht two tubes? i did it this way because i plan on taping each tube to the brim of each pot (2 pots i guess) so the co2 flows right underneath it and up

Co2 Tablets. with out dought the easiest way. :)

remember that the yeast will die if they are cold so the temps must be lukewarm where the yeast bottle is situated. so behind the fan next to a light or something does the trick. also ive heard that if you dont have HPS or MH lights co2 isnt very useful since the plant cant absorb it without having alot of light absorbtion.
