Cheap CO2 idea!?

[Mr. Happy]

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 garden. I can barely maintain 40%. So it just occurred to me to add baking soda. Would that help provide enough CO2 to matter?

Thanks, MH

No.
You would need to provide a catalyst (acidic) for the baking soda to release any CO2.

Go for a paintball CO2 system. Although I hav never grown MJ myself, it is commonly used in aquariums.

The way to get the available CO2 out of baking soda is to put it in a nonreactive tray, such as a glass lasagne pan.
Take a plastic soda bottle and put a TINY pinhole in it so that when filled with water, it BARELY drips out- a slow, controlled drip.
Empty a box of baking soda into the glass pan.
Fill the soda bottle with white vinegar and hang it over the pan.
It should slowly drip onto the baking soda, providing the acid catalyst necessary to release the CO2.
It's not ideal though. CO2 boosting is really only useful when you have provided all your plants' other needs.

Thanks to all, I will keep experimenting.

Doesn't that get pretty smelly?
