I sarted my plants at 16 light 8 dark ,I switched to 18 light at 2 weeks old. I just put them into flower 12/12. When I was putting in the new 2700k lightbulbs I put in a bigger fan, it really didn't fit. When I shut my door it wouldn't close so I tried to force it, it knocked a lightbar down and it fell into my tallest plant. The light knocked the plant down and it bent and it's most stretched node. It was leaning over like I super cropped it , I said fuck it and went to sleep. Eight hours later the plant had picked itself back up! The only thing is now the main branch is curvy haha. At least it's shorter now, it's still growing fine no real damage other then the light cut off a branch. I put that branch in a party cup with some fox farms and water and it's not dying or wilting at all. I think I might be able to make a clone out of it if it survives. I will add pics soon. The seeds were feminized so I'm not worried about males. I have the plants in almost lightproof box with a blackout curtain on top, in a closet, in my bedroom, with one window with a blackout curtain on it, and the doors shut so I'm not worrying about hermies either.
