I grow in the mn/wi region and have had nice results from starting plants right before may indoor and then outside first or second wk of june. Second wk this year cause we have had it soo cold and really no good rain that will soak. I planted six already sexed plants outside and now down to one. damn wind and dry temps and don't forget the deer and rabbits... oh and the one left is still vegging with warmer temps this coming week and a bit of rain I am hoping to make up some growth before flower.
