Outdoor Marijuana Seeds

I was wondering if some seeds planted marijuana and just left for about two months and let it grow naturally, will have grown when you see or do you need to care?

It is a weed my friend, and thusly develops itself. No, he will not need care once started from seed. My friends shed their seeds on their shoulders in the flower beds around my home. Moley Spirit! I found myself more than I knew what to do with. I do give them a little Miracle Grow from time to time with the rest of my flowers. The harvest was outrageous. Just learn the sex of sources online or elsewhere and pull the males. They are useless. All they do is make the weed woman seedy and add it to your criminal charges. You do not want to get to the weeds growing which has not broke ... Well, you know.
And do not get carried away by the hype. So many stoners seem to think that the brain surgery. Honest, yer just growin 'a weed. No need to overthink. Been there. ;)
PS Make sure he is planted in soil that has been cleared of weeds and other grasses which compete with it. You can also bury a fish in there for them to feed. (A hint of girlfriend of Jerry Garcia, Mountain Girl. His eyes light up.) PPS You have not heard all this from me.

I suppose, for the first two weeks you need to water / care for her to get the plant "has started," then it will probably become more resistant and can survive by itself.
