Well depends on if your going to order seeds or not? If its a hassle to buy seeds, you should just buy a decent bag of mids, and use those. You dont want to many, otherwise helicopters might notice ya. First grow I would try about 10 to be safe, or less, realisticly I doubt this will be noticeable by copters but its up to u. Hopefully you get about 5 females, and that should give you plenty of room for trial and error. try diff things on diff plants, find out what works for your enviroment, then get some good strains, and make it happen
