I live in NorCal, I tried it last year. Put a dozen 4' plants I had started indoors, out into the greenhouse in late Nov.
The plants did grow well, but the buds never fully developed, runny, sparse, airry, but frosty as hell. They had frost all over them.
Fortunatly I have a full sized hash making set-up, made it all into hash
peace
