I did a similar move a few weeks back. I needed to enlarge the hole for my 6" duct going through the ceiling in the grow room. I had moved the plants over to one side so I could get to the spot. I completed cutting the sheetrock and laid the sheetrock saw on top of the mh light I am using. I was vacuuming the area and bumped the light and the sheetrock saw rolled off the light and took both tops and a main side branch of of my first female plant.
I thought I was going to puke, so I ended up having 3 clones that were unintentional, 2 made it 1 did not. The hole that was left from the side branch sealed itself in about a week and a half and it was ripped, not broke so there is about an inch long scar on the side of it, but it is healed over with a brownish nasty looking scar, but it is flowering its ass off now.
Lesson learned - move the plants plum outa the way if there is anything related to construction going on in the grow room.
Peace
