Broke main stem on Auto :(

Not on autos but on photos ive re attached main branches that snapped clean off and repaired split main stems from too harsh LST.. and ive always used some kind of tape, anything from plumbers silicone tape, to duct tape and even mesh tiling tape. The common theme is you need to wrap the damages area WELL and not move the damaged area for a few weeks. Pretty sure this will badly stunt the Autoflower as it heals the damage instead of growing but If you got others going its maybe worth letting it go as an experiment to see how your patching job works out, use it as a learning experience. But if its the only plant you have or one of only 2, and you NEED it to produce a half decent yield then id prob cut my losses and sprout another seed while you watch this one for a week and then move the seed in and this one to the bin.
