My figs are all dormant and in the shed.  But I'm about to install my 400W HPS light in the basement to jump start cuttings this year.  Since I'll already have the light rolling, I'm considering bringing my trees that started last year in to get some additional growth this season.  

My question: will breaking dormancy months early harm my plants in any way?  My understanding now is that it goes dormant for efficiency purposes.  Does it need a full winter for any reason?

i have some i never let go dormant. just make sure they get enough light.

 I have grown several of my outdoor trees as indoor plants their first and/or second year.  Haven't noticed any down side to it, and it does give them a jump start on the season.  I have a hardy chicago and amy favorite unknown sitting in a south facing kitchen window right now.  They think it's spring and are growing gangbusters.  They'll go into the ground in April or May.

I live in zone 10b and my LSU purple don't go dormant completely: they keep one or two leaves and then at the end of February start growing again and go partly dormant in July.
It is all up-side down from up-north!
It is December the nine and this morning I had a Banana fig and a Strawberry fig from my small trees. I believe it is the change in temperature that is needed more than dormancy. Here during the day it is still in the low 80 and at night it goes into th 60 but in some plants there is some small growth. The dormant period is about a month, from the middle of January to the middle of February when during the night it goes in the 40F.
Most varieties have lost most of the leaves but Janice Seedless, Banana fig and Strawberry fig are still ripening. LSU purple ripened the last ones about a week ago. LSU is the one with most leaves still.
