Greenthing Reviewed by Greenthing on . how to make a Poor mans CO2 Its very easy. It will run 24/7 but will need a little maintanance. You will need a one gallon milk jug. Fill it 3/4 way with warm NOT HOT OR COLD water. 2 cups pure sugar 1 pack dry yeast(anykind of yeast that still works) add the sugar and shake to mix it up. Then add yeast to mix in and skake for a few seconds. set the milk jusg above your plants the yeast will produce CO2 and it will overflow the milk jug and shower down on your plants. Rating: 5
