New to indoor need help with terms

i decided i t would be best to try indoor growign after my last outdoor crop. it all happened when one day i took them outside to take the sun, there were four plants, when i went back to get them in for the night tehre were only two left, yes... someone took them, at least they only took half and not all of them.

Well i tried reading the growing thing for noobs but needles to say my inexperience and english are not helping me to understand.

Iḿ thinking of growing in a space about... 5 (height) x 2...3...4? Well iḿ thinking of one plant for my first time, hence the space size... itś my closet, itś a lot bigger but i dont want to use all the space, no ventilation except for the one in the room. well i kknow what a plant needs to grow, i just dont know how to provide it artificially.

i know i need light, i' ve read abotu the kind of lights, and white paint ( will foil paper work too?). so that i understand a little bit, i just dont know which light shoudl i use for the space mentioned. I dont understand ventilation and when fans are mentioned i dont understand if we're talking about normal fans that one would use to be fresh on a hot rio de janeiro night or will i need other type of fan?

any help or tips will be appreciated as i want to udnerstand what i'm getting myself in to before i start off
