No, you don't get it. A CO2 tank and enviro control unit are a luxury.
Seltzer water is about $0.79 a bottle, is misted on leaves where evaporating CO2 is used. Those numbers of hundreds of dollars you pulled out of your rear are BS. I might go through 3 bottles a week at a cost of $2.40 to provide my plant micro nutrients and some CO2. Your argument looks pretty silly now. I gave ya sources, you make up figures, I prove you wrong yet again. Why do you continue? It has been proven to be beneficial, and if someone wants to spray their plants with seltzer water, more power to them. Sorry that doesn't satisfy your need to control what others do.
All your doing at this point is displaying ignorance.
