really stupid questions

please dont b 2 harsh with me...i dont no shit bout growing. i live in florida so i was wondering if i planted a couple seeds from the maryj i have been smoking could i grow a couple plants in my back yard (there is a 3 foot fence with a shed 4 feet away that will block the area i was thinkin of. so my stupid questions r as follows;
1. is this 2 small of an area
2. do i need to wait for a particular time of year to plant
3. how do i no if the plant(if it grows) is a female
4. should i put down potting soil, or a compost pile in the area i was planning on
