"Everyone romaine calm! I have come here to chew bubblegum and kick ass, and I haven't botany bubblegum."

To make it extra evil, Vivi for short.

(ducks for all the Final Fantasy fans that now want to kill me)

I think this would be where "evil" falls into a grey area.

That’s it, I don’t think we’ll find a better one!

In the average day, a person breathers out 500 litres of co2 in a day. So approximately 20 litres per hour.

There is no way that amount of plants is converting that much co2 back into oxygen,

If this rig is air tight, all this person is doing is slowly poisoning themselves with co2 and lack of oxygen.

For some reason I remember something like 8-12 fully grown oak trees being the minimum to sustain a person. I think it was in a thread about surviving in a bunker or fallout shelter.

Not a biologist though, so you'd better do your own googling
