one day i was chilling in my backyard and i noticed a small plant in my dirt. i looked closely and i noticed it was a marijuana plant. "dont ask me how it got there, i just dont know" but i desided to grow it. i put it in a small pot and water it every other day.should i water it more. i dont have any grow lamps or anything (im too damn broke) so i kepted it outside. so far its grown some 4-5 inches. i was wondering if one of you out there would help me out with this. ill take any advice anyone gives me.
