i was looking for something simple and found this really cheap way with the 2 liter bottle and the air hose with the mixture of bread yeast, bakin soda, and sugar... would anybody suggest or knock this down? im guessing you cant really regulate how much is produced, so can you add too much co2 or is better the more u have?
Many many people use this CO2 making method on these forums, they usually mix it up in a milk bottle and fix a hose to it making the co2 go over the plants. Im pretty sure u cant have to much co2. However i may be wrong. Bionic
increased co2 levels requires better lighting, to ensure the plants get the correct ammount of light to co2 ratio as they usuall would
yes you can have too much c02 but you are not gonna get close to that level with this method. You would need a c02 burner to get a toxicity
