You would need to provide a catalyst (acidic) for the baking soda to release any CO2.
psteve Reviewed by psteve on . Cheap CO2 idea!? I am sure this has probably been thought of before but I have been trying to problem solve on an inexpensive way to provide my plants with a constant supply of CO2. I have tried Yeast. Can't really tell how much CO2 it puts out. I can also create odd odors which draw suspicion. Anyway, this is my idea. Please tell me what you think. Simply this, adding a shit load of baking soda to my humidifier. During the winter the air gets so dry, I need a humidier going constantly in my closet Rating: 5
