help me with my setup??

so in the planning stage of growing :\

i have a 2'd / 3'w / 4't space (indoor closet) to grow in.

and i have a seed that i really want to grow. Some Royal Bubba that i got from a clinic and stoned me harder than ive experienced in a while.

so i was wondering what would be the best way to set up the area i have ??

and what items/materials should i buy to make it the best. although i dont want to spend much more than $300.

If anyone could be of help id greatly appreciate it!!

oh and im only looking to grow one plant in there at a time, no special reason just not looking to go overboard for my first time
