My response likely to annoy some of the more seasoned growers here......
a seed fell out of the single joint I thought I would enjoy this year. It was mid May, and I pressed it int my flower pot on my deck, about an inch deep and promptly forgot about it (amazing how that happens when I smoke da ganja!).
2 weeks later, a friend points out to me that I have a wee weed plant next to my geraniums. I yank it and re pot it, she falls over, seemingly dead, and next am, she is straight and tall and healthy looking. She had a full summers worth of sunlight everyday.
knowing absolutely nothing, I feed her (who knew then that there even were he's and hers) plenty of miracle grow and yield myself a solid pound of smoke after I harvest 2 weeks ago a 7.5 foot tall plant with buds everywhere.
so, this site has helped massively. Great people and great learning to be found here.
my advice: outdoor growing is a snap. Indoors a PITA.
