Hard to stop deer, armadillos, rats, etc. if they are really determined but back in my younger days I did nothing but guerrilla growing. Human urine works about as well as any. I would piss in a gallon milk jug and refill longneck beer bottles as needed. You put them in the ground at an angle so it won't just rain straight into them...don't worry about the amount you put in them, one third bottle is plenty. The more bottles the better. Someone mentioned Irish spring soap...buy a big pack, use an old cheese grater and cover the ground in and around the grow. That will also help.
