Hey Dank,
I tried to tie down my plants a little bit like you've shown, but I'm wondering if it is possible to bend it too much (without snapping it)? As I'm just using a 90W LED I wanted to try to flatten it out as much as I could and I have one of them down at about an 90 degree angle (did it over a period of a few days). I'll probably take a few pictures this weekend--I have just been updating on the weekend.
The one I have really tied is the Orange Bud I switched to 12/12 and almost killed by overwatering in crap-soil, but it looks like it might survive. I don't think it will really produce anything from how it is looking, but I'm not giving up on it yet. I also started to bend down one of my auto-flowers as it got a fair amount taller than the one next to it--must be a taller strain (Auto Berry v Auto AK). I know everyone seems to be really negative about the auto-flowers, but they're looking pretty damn healthy so far. I think they'll be good for me for a first successful grow while I'm learning the 12/12.
Anyway, I don't want to over-tie them and know that you've gotten some pretty good results. With my space issues I just think that bending them a bit will suit me better than just going straight up like some others do. We'll see I guess...
