They don’t use enough oxygen over night to negate the effect as they use the carbon to grow. It’s still bad to have a lot of plants in your bedroom, but it doesn’t really matter as long as they are relatively small.
That had me go and look it up and apparently you’re right that they use part of the carbon dioxide as energy storage, but as I understand this storage eventually gets released in full when the tree dies too…
Not sure if that would be so much to balance it out again, but it does still diminish their overall effect even more…
It is just how a tree works, it gets the matter to grow from the carbon dioxide. If they are burned or they die this carbon is slowly released again, same way as coal has carbon that is stored until burning
They consume oxygen during the night so when you have a lot of them it can cause respiratory problems, that is for the bedroom
An effective HVAC system makes this a non-issue. It isn’t like the air is stagnant, the air handler keeps air moving.
