the main stem of one of my babes was damaged when it was being transfered, it was completely crushed in one half inch section about 4-5 nodes down from the top and really splintered bad. I bound it up in some velcro gardening strips and tape and tied a bamboo stick to the stem for support, after about a week I removed the splint and bandage and everything was nicely healed up with only a fat knot in the stem to show for its damage. This was 1 of 2 plants, the one that had been bandaged was actually about 3-4 inches shorter than the other one, yet showed no lack of vigor compared to the other. This happened and was done during the first week of flowering.
