Well, like sticky mentioned you don't necessarily have to camp out with your plants but why is this a disadvantage? Remember we're talking about deep, deep, unexplored woods (it's gotta be a real good spot, don't know where you're from) The theory here is if you're willing to spend the time you could clear cut a garden of enormous size that supports say 30 plants. If done right, outdoor plants can yield up to a pound of bud. You do the math, 30 lbs could make a commercial grower almost $100,000 for 12 weeks work!
