ok so i forgot the questions

OH! ok the water should be ok, just check the ph. some say its good to use water that fish swim in cuz of the fish crap. The light thing, i dunno about that. would probably just attract popo copters flying around looking for grow sites. Human hair does work. It keeps deer away. You could also go get some fox piss from a hunting store to get rid of things like squirrels and rats. Anything else use a bb gun. Unless its someones pet.......then get the hell out of there! and um, you harvest after they bud.......duh!
