My stretched plant snapped under the weight of the cola when it was about 5 weeks flowering and i found floss to be useful. I tied the top to nails in the walls cuz i didn't think a splint would provide enough support for such a bad break. The plant showed signs of stress for only 1 day, and was totally healed up in no time. I also tied the side branches to the main stalk cuz they were droopin from the buds.
