Seeing what if happens if you give vegitation different kinds of air and gases

For vegitation inside a chambre:
Periodically putting a little bit more helium inside a chambre together with normal air
Periodically putting a little bit more xenon inside a chambre together with normal air
Periodically putting a little bit more argon inside a chambre together with normal air
And more gases of the periodic table if possible

Periodically putting a little bit more CO2 inside a chambre together with normal air
And more gases
