Grab any tape you have in the house worth a shit, preferably duct. You'll need twine and splints as well. Make splints out of sticks, then go do your repairs. Use the twine to tie the plant up to itself. I'm assuming you are in flowering now b/c duct tape isn't something to be used for vegging plants. I should make a guide for this, 4 hurricanes in Florida taught me well.
