Thanks a heap EoF, every bit of that post was helpful. I'm not much for panic, so I got it duct taped with about a 2cm border beyond the cut on either side, then I laid it back down on the paracord within 30 seconds time, I think I gave it the best chance I could, so I don't feel hope is lost yet. That said it did make my heart sink quite a bit, I've never had something that drastic happen in any grow canna, or vegetable. I think the pattern to be found in the two oh crap moments I've had is that I should go medicate *before* getting to work, I tend to work slower and more deliberate. I'll go in and pull 4 of the biggest olfending fan leaves, thanks again for the advice and comfort, it's much appreciated!
