I am searching for a list of plants which are easy to maintain, small and would produce enough oxygen for one person in a 25m² room.
Until now I just found two sources:
I have a great deal of skepticism about the idea that less than an acre of plants in full sun can make a substantial difference in the oxygen levels of an enclosed area. Most tropical plants that are inside are receiving from 100 to 500 lux.
Outside in the northern hemisphere on a cloudy day is around 50,000 lux.
How can you reduce the amount of light by a factor of 100 and get the same amount of photosynthesis going on? I see a commonly quoted figure of "Plant leaves produce 5 milliliters of oxygen, per leaf, each day." but I don't see under what conditions this is measured under.
I don't think you can produce enough oxygen inside a room unless the roof is glass and you fill it entirely with any type of plant.
