We finally got relief from the heat today. It's been well over 100 for the last several weeks, night temps are dipping into the 70s. Got some rain today and it cooled things down quite a bit, it was 66 degrees on my way home from work. How long does it need to stay cool to get fruitset? I don't want to get my hopes up, 24 hours is about the most I expect before the oven is back on.
