Carbonating plastic keg?

[blagooba]

Hi all

I have one of those plastic kegs with the co2 valves on top.

My question may seem stupid but do the co2 canisters carbonate the beer or just help it to poor?

If so do you still need to add priming sugar?

Thanks

They can do both but you will use up a canister of CO2 quickly if you use it to carbonate. It will be better to use priming sugar to get the carbonation and the canister to maintain it while consuming.
