Interesting subject.. I'd have to say that the pros and cons to debate, would simply be the pros and cons to indoor gardening vs outdoor gardening. If you're going to grow outdoors and have the ability to grow using trellises to form a nice, wide, even, canopy to produce a monster yield... I can't see any problems with that haha, sounds like fun to me. The only problems I see with that is that you sound like you're talking about "farming", and thats a lot of work unless you've got helping hands all the time. If you can handle all the labor work of it and all that, then go for it, with a little fine tuning and practice you'll have a pretty insane garden, at least based on what I'm picturing in my mind. Other downside could be visibility. That intense of a grow outside would attract a variety of preditors, I would think, such as thieves and destructive rogue humanoids. Not to mention the legal aspects of it if you aren't growing in a legal state, under the guidelines laid out by your state government. I always forget that there is a large portion of the country where there is no such thing as medicinal marijuana programs or laws, and people live without ANY ability to legally obtain or produce their medicine.

Anyways... I'm sure I could think of some more on it after a while here but I'll start with that.

Of course the positives of these gardening styles you're talking about are focused around the yield and quantity of bud you'd harvest.. which could potentially be tremendous, haha. Also I know a lot of people don't like outdoor grown bud for some reason, or just like to think they don't like it.. but I believe outdoors can produce some of the best buds in the world.

Lemme know what you think about this stuff as well, I'd be interested to know more details about exactly what kind of garden setup you're thinking of.
