Lol. First off..
How the hell do you drop a plant from a 2nd floor window?? Or any window for that matter? Lmao. Sorry I'm just really curious on this story for this instance.
With that being said, check out my first grow journal. And the one I'm on now. You don't need to read them all. Just the first bits of pictures. That will be your answer on just how much torture plants can take lol. It should make you feel better.
First grow one is good for a laugh and the second one I had my lights fall on it, and it looked AWFUL, and somehow it pulled through. You can probably trim off anything broken and wait a few days for the new growth to appear, as long as its not all broken of coarse![emoji2]
