Hey Mater,
Good to hear things are going well. I'm not sure what it is either, but I had the same thing happen on the 5th of July...we had a couple-few really nice hot days here, and I had 40-50 tomatoes ripen in that time span.
Kinda sucked to tell you the truth, I much prefer the slower 2-3 ripen a day harvest. Bato bucket res. would have saved you from any lack of water failure if it was just one day I think. But then again I don't deal with any temps over 90...ever.
I had to spray too, but remember the "Safer" brand product is still organic, and is an edible enzyme I think.
I would love to see some pictures
