Marijuana grow closet from scratch

A question from a starting grower:

How do I make a small stealthy grow closet for first try??

Area – height, width, depth? And where is this closet going to be? In a large house with a decent size property surrounding it? Or in an apartment or condominium setting? These will greatly determine the lengths and amount of money you will need to invest in odor counter measures.

Small closet. May get small grow tent? 2 feet x 3 feet x 5 tall… It’s not a money thing as much as trying to go undetected from house cleaner, kids home from college etc…any help greatly appreciated…
PS just starting 1-2 plants, already in 4/5 gal bucket.
