I'm of the opinion that autos may have some kind of panic mode survival trait. One three occassions now, I've had badly damaged autos, not only recover, but also turn into the largest plant of the grow! My very first grow on afn, a Sliff Seeds White Widow, got broken on the main stem at arounbd the second or third node.And I mean 90% broken off! I stood it up and tied it in place with yarn. Withing three days it was healed together. Then she sat and did nothing for about 2 weeks. Then.......... she became a monster! I grew 2 of these WW. The undamaged on gave me 30 grams dry. The broken one? 168 grams dry!
This happened again. My dog pulled a Blueberry Dommina out of a pot of coco. It was just transplanted the day before. He ripped it completely out of the coco and it must have laid on top of the coco for an hour, it was wilting. I almost tossed it, then said, what the hell, if it dies, then I'll toss it. Once again, the biggest plant of the grow out of 4 plants! Always take the time to give a plant a chance, you'll often be glad you did!
