Outdoor experiment

[Privatebrowser]

So after moving to warmer climates I found a ropey guy to get a bit of smoke from and turned out there was a seed in the bag, so being curious I popped it and planted it and have left it to grow outside . There have been days of 26 degrees and nights at 3 degrees the rain has come in buckets then dried up for days but being an experiment (I plan to buy seeds and grow properly at alter date) I have not fed any nutes or messed with, all I did was pin a couple of branches down because I had 6 branches bit all going vertical parallel to the main stalk.
it's been 14 weeks but nothing seems to have developed over the past 2-3 weeks.. any recommendations as to whether I leave it or crop it, maybe it won't advance with out nutes I don't know. As you can see by the pictures it has endured some hardship from wildlife and the changes in weather but at the moment it stinks to high heaven but doesnt seem anywhere near finished
