diy co2 enrichment

i was wondering how to make my plant grow faster and i thought about a system that is to built and it is used to enrich aquarium water with co2 for controling ph!so u will need
-a 2litre bottle of cola
-3cup of tea sugar
-1/2 of tea spoon yeast
-small host that is used for aquarium air pumps can be found in any pet shop!
so here it is!
boil 1/2litre of water and put the sugar in it until the sugar melts in the water!
add 1litre of tap water in order to make water's temperature 30c then add the yeald!put the mix in the bottle and make a hole on the lid of the bottle put there the hose and seal it with silicon!thats it from the other side of the host in 12 hours you will have pure co2 produced with rate of one bubble in 2 seconds not a big amount but i think in a closed enclosure it will be quit helpfull whats your opinion should i try it?
