I know the importance of CO2 in the grow room and I knew having extra would be a good idea but I never wanted to spend the money to get a system to make extra CO2, but today I read a cheap and easy homemade way to get extra CO2.

All you do is take a gallon jug like say a milk carton and fill with a pound of sugar and mix enough water in to dissolve all the sugar. Then put yeast in there and cap it off. Lead a tube from the cap of the container to your plant area and you have your own homemade CO2 production for nearly nothing spent at all.
