After reading your comment, I Googled it and guess what, there is no indoor garden like this not only in New Delhi but probably in the whole of India. And maybe it exists somewhere but I couldn't find any information about it even after searching with different keywords.
We have indoor plants but no indoor garden! 😅😅

I suppose it makes sense that most glass house gardening is done in cold weather counties. The two biggest conservatories are in the UK.

Maybe you are right, it must have some connection with weather and temperature. As far as I know, indoor plants grow only at a fairly balanced temperature.
