Hello, this is my first time growing and my seed just sprouted, but I really don't want it to take too much space or be too noticable as people around here are judgy. I'm growing outdoors. I've read that topping plants and LST might help. I also don't know if there's a way to induce flowering? I don't care too much about a big yield as I'm not a regular consumer and doing this just for fun.

Hi, yep Topping and LST will both help keep your girls short and bushy and stop them from looking like Christmas trees.
Not much you can do to induce flowering outside, Autos will flower whenever their time is up and Photo Periods will finish in the fall.
Good luck and have fun!
It’s BlackBerry Kush from Dutch Passion actually, thanks a lot for your help!
You're probably ok, but it really depends on the strain and how loud it gets.
