How can a terrarium be air tight? Answered

The office where I work has a no plant policy; they're afraid the water will spill and ruin the furniture and carpet. However, I think I can get away with a terrarium. However, I'm am wondering how plants can live in an air tight environment. Eventually won't the plants convert all the carbon into oxygen and suffocate?

Plants also generate CO2, as they respire the glucose they make by photosynthesis.

However, your plants are unlikely to be in the terrarium alone - there will be many tiny and microscopic organisms in the soil, merrily consuming oxygen and producing CO2.

One thing, the reduced "supply" of CO2 will do is slow the plants' growth, so it will take them longer to grow too large for the jar.

No plant means that; if there are plants then they are not allowed.

I don't recognise you, so I'd say not. What does your boss say about a terrarium?

How sad the cost of carpet/furniture is a more overriding worry than your employees' welfare - I hope you are still allowed to walk around the place and sit on the chairs though.

I built my daughter a couple of terrariums for her classroom, but chose to not make them air tight -- I punched some little holes in the plastic lid (of a huge plastic container). She only has to add a tiny amount of water every 2-3 weeks, and the plants are all doing well. It seems much easier to manage condensation than with an air tight setup. To keep the office police happy, you could do something similar, only fasten a piece of thin felt to the lid so it appears to be sealed. Just a thought.....
