The carbon dioxide scrubber that uses soda would probably be satutated with CO2 quickly if you are making a large batch, and would necessitate either a larger scrubber or more chemical; but the nice thing about a chemical CO2 scrubber is that the soda can be regenerated by heating it. If you are going to go to the trouble of setting up a separate vacuum tank, it would be easy to pass that through a carbon dioxide scrubber; then, later, you could heat your carbon dioxide satuated soda in your green house and drive off CO2 to be used by the plants in your greenhouse. A word of warning; plants do utilize carbon dioxide and water to produce carbohydrates and other nutrients, but only in the presence of light. If you suddenly increase the CO2 content of greenhouse that is not well lit, you could end up causing an acid-base imbalance that is detrimental to your plants.
