I have no idea how this works, new to site, new to growing...friend tossed some seeds in garden and whoops the damn thing is 7 feet tall now and I just hope the neighbors don't see it. Looks like buds all over the place, sorta white, sorta green - what happens next and when. It's a mild climate here.. someone told me to try to hold out till just before first frost. Is that right? then what????
