B1 is like Novacain for your plants. Feed B1 to them before you start digging to keep them from stressing. B1 is safe with your nutriants. They sell pure B1 at home depot. its really cheap and very worth it. Directions are on the bottle. I use it all of the time for cutting clones and anything damaging to my plants. your plants won't even know they were dug up if you give them B1 first.
