A while ago, I saw a documentary where they had a big-ass fan on an apple orchard, which they would turn on early in the morning.
The problem is that when it cools down in the night, it can dip below freezing temperatures, which would damage the blossoms, if it stays that low for too long. And the cold air gets trapped between the apple trees, so just creating some artificial wind is apparently a pretty good solution to untrap it and therefore allow things to warm back up as soon as the sun hits.
Just found it interesting that this is a common enough problem, without requiring more drastic solutions like actual heating, so that they came up with this idea.
The documentary is in German, but you can see it at 5:00 here: ardmediathek.de/…/Y3JpZDovL3dkci5kZS9CZWl0cmFnLXN…

This is only done when there’s an unexpected frost in spring or summer when the poly tunnels have been taken away.
