I don't prefer growing trees inside home. At night, plants releases CO2 gas. This is harmfull for us, especially during sleep. It is good to grow trees in open air.
There is danger only if you have the habit of keeping your windows closed and there are plants in your bed room...Having a few plants in the sitting room is very decorative besides being healthy since they absorb carbon di oxide in the air for photosynthesis...
Pay no mind to those who talk behind your back, it simply means that you are two steps ahead !!!
