I seen someone made CO2 in a 2 liter soda bottle with yeast, sugar, and water and then made a hole in the cap for a hose to be put in the cap, but i don't know for sure how much was used. I made some today by guess work, it's been 2 hours any no bubbling yet, dos it take time? or dos someone have a exact set up (2 cups of this, 2 tablespoons of that, etc.) and the hose thats in the cap dos it dave to go straight down, or can it go up, and then down to the plants? I do know that the exhaust, and the inside fan have to be turned of, but how long? I don't want to buy a tank for the small amount i'm growing and it's winter here and i don't want to leave the basement windows open just to let some CO2 in.
Thanks
Thanks
