Default nutrafin CO2 system

hi,

if I buy this CO2 system, is there a cheaper "co2 generating source" that I
can use later instead of buying their co2 generating chemicals?
(yeast/sugar, etc...)

also, how long does a typical chemical mixture last for a low KH, 30G
aquarium with moderate planting?
