green poison extremely long growing period

I received a free "green poison" seed from Attitude seeds, so I gave it a shot and planted the seedling on June 1. It was supposed to take about 49 days and is supposed to be a sativa/indica hybrid. Regardless, it took 121 days to mature and appears to be much more of a sativa plant. Anybody have any ideas why it took so long? (at least compared to the described time of 49 days)

Love to hear any rational explanations
