Smile CO2 Production using Citric acid powder and Bicarbonate of soda.

I have a legal indoor medical marijuana grow. I've been looking at those buckets of powder that produce CO2. I'm thinking to myself "There must be a way to make these yourself in bulk for less money."
I Don't know for sure (I'm not a chemist) but I suspect these buckets ($60 Each) contain anhydrous citric acid powder and baking soda and function by absorbing ambient humidity which activates the chemical reaction between the two allowing for a slow steady production of CO2.
I have two questions.
#1 Would the above concoction ( Anhydrous food grade citric acid powder and baking soda) function in this fashion by slowly releasing CO2 as it absorbs ambient humidity?
#2 If the answer to the first question is Yes then in what ratio should the dry ingredients be mixed for maximum efficiency?
Thank You for your time and I hope you find this at least a moderately challenging yet basic set of questions.
