these accidents can help... several times this happen to me.. and after the plants tissues repair the wound it will have a huge bulge of vascular tissue and it be like a muscle.. simmilar to supercropping... it should be ok as long as it isnt completely detacheddont worry man my fan fel on my sog bent down 2 plants i put a piece of tape around the part it bent and cracked a bit so to keep the air out and it notted up on the break point. I also tied it up to the ceiling to hold it up and the mofo grew into a big bush mofo shes a bit shorter than the rest but much fatter. so i wouldnt worry might even stress the plant enough to creat buckooo buds hope this helps good luck
