Yep. Just tie it back up to where it goes, and just having the broken parts make contact with each other is enough for transfer of fluids to take place... Just try not to fuck with it at all after it's tied/taped back on.
When are my buds supposed to turn into nasty clumps of mold? They're all dry and have had the sun shining on them all day now. They look perkier and the purple strains have really got a lot more color to them now that they were wet and cold for a night. The Black Widow has only got a few more days, I can see the trichromes turning amber with just my eyes.
