Help needed for tiny steps into gardening | New Gardeners | Commercial Hydroponics farming in India

Hi All,

I am a resident from Chennai having plans to start off with my own organic garden. I have no hands on planting and nurturing so far, and trying to start off on it now. I would like to try cultivating a single plant or 2. Can anyone suggest which plant would be ideal for a beginner? I read at a couple of places green chillies, tomatoes etc are quick grows.

And as well, the rains have started off in Chennai right now. Would this climate be suitable to cultivate a plant or should I wait for January or so by when, rains would be gone?
