Getting more C02

The space I'm starting my grow in is a huge attic. So I will be laying some areas so that heat will stay in, but I want to pump in as much C02 as I can. Since this is an attic what can I do to pump in more c02? Just get a simple air pump and run it into open space? Or is there a better option?

Well not really because you need CO2 which can be gained by burning propane with a pilot setup or a bottled system, roots need O2 but the topside needs CO2

CO2 can be generated by putting yeast and sugar into a 2 litre coke bottle that is half full of warm water. About 30 minutes after mixing, you will see bubbles. These bubbles are CO2, the byproduct of the yeast eating the sugar.
