It's being lucky with the temps and the timing-may or may not work. Once past a certain point, flowering is unstoppable I am told. We shall see. s'only a clone, and if it revegs, I shall flower as normal.
I shall kick it into flower as daylight goes 12/12, and put it out when temps stay above 10c overnight (may keep it in a pot so I can drag it in if needed) good luck with yours, lets swap notes on it.
