December 16 will be the first date this winter when temperatures will hit a low of 26, or so Google Assistant tells me. I checked in with my variegated lemon tree to find out how it’s doing in the grow house.

I’m astonished with the new leaf growth. I believe the liquid Grow fertilizer I provided earlier this month is fueling some of the new foliage. Lemon trees supposedly don’t go dormant during cold weather, so I need to keep a constant eye on this tree for any signs of problems. I’m hoping tonight’s cold snap won’t damage the new leaves.

One thing I’m a little frustrated with is the automation that switches on the Vavofo outdoor smart outlet in the tent under specific conditions. I created a script in the Smart Life app to turn on the lights when local temperatures are equal or less than 48F during daytime hours. I’m currently troubleshooting why the app doesn’t fire consistently.

Obviously if I’m not home or paying attention to local climate conditions, I might lose my frost tender plants to cold weather. Turning on the incandescent string lights helps mitigate the freezing temperatures by keeping grow tent temps 4-10 degrees warmer. I may try using IFTTT integration to get this to work reliably. Worse case is moving to Home Assistant and running my own automation server to control my IOT.
