OUCH! Been there, done that, HATE that..... but it happens. Anticipaipating doing that a lot with my height limitations. Sounds like a strain best saved for the great outdoors. Something that worked for me to manage stretch in a tall sativa I once had..... Kept cool lighting (MH/coolwhite fluorescent side lighting) for the first 2-3 wks of flowering. Keeping cool white fluo, switched to warm lighting (HPS) for 2 wks, after that switched out the cool fluor tubes for warm white. Lengthed budding time about a week, but almost 50% less stretch. Too much trouble, no more tall girls for me after that. Worth the effort? Depends on how much you like the strain. ~~~ PEACE! ~~~
