As a supercropping fan, i have intentionally broken, snapped, and crushed lots of mainstems and branches. Sometime i got carried away and completly broke it in half with only a few strands connecting the top and bottom. Amazingly, it didnt hurt a thing, and i found if i could somehow hold the break somewhat together for a about ten days without a lot of movement, it would heal and form a big ass "knuckle" right at the break, and it was stronger than the main stem. Those supercropped plants always seemed to do better as far as health and yield, but i never did any head to head comparisons on the final yield of the "broken plants", but it was clear that plants that had broken stems/branches suffered no loss in health, vigor or yield in the end.

I dont hesitate to break down a taller growing plant to keep it from frying in the light.

GaGrown Thats an interesting idea. I use it in my small sog garden at times with plants that are near the edge and need more light. You have me wondering what if.... i did that with all of them in the 3rd or 4th wk of bloom. Its a little harder to do with clay, but with rockwool i could lay em down flat on the sides if needed. Good growing all.
