“HOW TO REVERT FLOWERING CLONES INTO VEGETATION
The optimal timeframe to take your “Monster-Cuttings” is around 2-3 weeks after switching to 12/12. When you see the formation of the first buds, it’s time to take your cuttings. Place them into a glass of water for some time to ensure that no air to enters the vascular system.
Now, you simply switch back to the light cycle you prefer for vegetating your clones, meaning 18/6, 20/4, or 24/0. You don’t need a lot of light intensity at this point. CFL’s with a daylight or “cool white” light spectrum get the job done. If you remove buds of your clones at this point, they will revert into the vegetation state.”
The light cycle is as important as the prep I believe. I could be mistaken.
