I'll keep it simple, straightforward and specific for you. You want to buy a minimal number of seeds, preferably already female so you don't have to grow more than one at a time to get a female, and you want a high potency plant that flowers fasts and stay short and squat.
Seed boutique, Female seeds, maroc, 4 pack.
it will only cost you 25$ plus handling, I reccomend never sending seeds to the place you grow. To keep it small start it mid summer, that way it will start flowering sooner.
A five gallon pot full of good potting soil is all you need. there is plenty of good advise on line about how to germinate seeds, look and you will find.
One word of caution, it sounds like a dangerous place to grow, keep to your plan of one small plant at a time.
hope it helps
