Humidity isn't a huge factor, almost always under 50%. The cola was just so dense that its internal humidity must have been close to 100%
I will have the ozone on a timer so that it isn't on constantly. I will run it for a 12 hour period at first though, I'll go hit the beach while it's on. I just want to make sure any spores (mold, mildew etc...) are all dead before next grow. I also have an attic fan in the space so it can clear out the air fast once I get home.
I didn't take any pics of the early signs of bud rot, the way to tell is the small fan leaves of the bud start to die and turn brownish at the base, then they will pull out very easy, almost no resistance, that is when you know something bad is happening inside the bud.
None of the other plants have any signs of bad things happening, they aren't nearly as thick as this was. That picture is on an 8x11 piece of paper and minus the top three inches, so it was close to being a 4x13 chunk of bud.
