Oh, I'm not disputing that growing weed is easy, that is why I said minimal greenthumb.
I'm noting that nobody has mentioned the necessary room to grow pot.
230RN - That brings up another point. Growing pot may be easy, but how easy is it to grow *good* pot? How much work? Working off from what I have heard, making good pot requires sexing the plants to make sure the males are removed, as unfertilized buds are the best. You have to fertilize carefully, as too much or too little negatively affects the quality. You have to provide the right amount of light, harvest at the right time, then process the buds and leaves yourself.
While perhaps not difficult, it takes research, time, and effort. As opposed to nipping down to the local dispensary and buying some good stuff straight up.
