Outdoors organic is the best. Find a nice clearing in the woods and plant em up. the only thing is if you have an indoor set up you can do early flowering and weed the males before you put em out. i just start 20 and wait till flowering to pull the males, which is quite a bit of wasted energy depending on how much i have to water but its cool...good exercise. There are a lot of things to worry about outdoors (pests, animals, people, choppers) but theres plenty of problems indoors too. it does cost a hell of a lot less to get the same yeild though and unless you got hydro inside the buds are better outside in my opinion.
