I have a little experience with Southeast Asian strains. We have no problem getting them to bud in Hawaii on our natural photoperiod.

I would start with 12/12 for three weeks. After that, every day I would knock off two minutes of light. By the time she is ready to harvest, she will be getting about 9 hours of light per day.

In my experience, these strains need to be very gently shocked to go into bud. Too hard, you get scragily bud. Not enough...even scraglier bud.

That's my 2 cents....
