it's about 60 or so days away from the shortest night. if you harvest before the year is over you should be ok. about the 2nd week of the year if the plants haven't been harvested they'll begin to reveg and flower at the same time. gets some really ugly looking growth all over the plant. this will continue until you rip the plant out because it'll never finish or you manicure the living daylights out of it. come the 21st of march the plant should have finished revegging if it's going to. Now, should you have the plant growing at that point be prepared to make a monster. it won't finish until the fall harvest. we just finished harvesting one of mine that we put out early in the year. i'm also in so cal, close to the beach and near LA. weather isn't too big a problem. i cover mine during the rains at this time of year. we just started the final set for the year this week. it's a 6 1/2 week flower so it'll be done easily before christmas. it's supposed to be a cold one this year with not too much moisture so you may be in luck. a good thick layer of mulch will be necessary if your in the ground. if you're in pots then do a double potting to retain the heat in the root zone. basically pot the pot that the plant is in. that sounds funny, but trust me, get a larger bucket than what the plant will fower in. poke holes at the bottom, fill with perlite on the bottom and place your pot in there. then fill the rest of the sides with perlite as well. it'll help keep the warmth in once it starts getting really cold. if the roots get too cold then you have no growth at all. just my thoughts with a bong rip!!
