Decent idea or terribly unnecessary?

Hello fellow growers.
Just walking down the aisle of our local dollar store and came across these clear plastic bowls.
My grow is on my mind 24/7.lol
I was wondering if placing these bowls upside down over my seedlings to first week or so and running a tube into the bowls from the top connected to a diy co2 mix.
Is this just useless or will I benefit from it.
Bowls are not completely sealed so fresh air can enter as well.
Just wondering? It would be easy enough to put together.
Thoughts ?

how are you going to measure co2 levels? what happens if it gets up to 2000ppm?

Good point I did not consider this factor.
So there is a possibility that I might over load the plants with CO2?

yep.

save the co2 idea for a sealed environment with larger plants, higher temps and tons of light.
