I live in a southern state (urban area tho), and I'm having trouble with year round. We thought we could start the grow to start to flower process indoors, then move them out continually, by the fence, and house and garage, and keeping them in a discreet from the neighbors view places.
It depends upon the strains I guess, but flower time is so much longer, that it is difficult to keep mother's, clones at an indoor managable size while awaiting outdoor room and keeping within legal growing limits.
And even though we keep it clean and ozone, eventually around a year old, the mother plants contract powder mold.
