Coldest Time of Morning

Hi ~

What time is the coldest time in the morning? I need to set a timer for the mini-lites around my frost-tender plants.

Thank you,

Nancy K.

Good Morning Nancy K.,

Great question, very timely. Thank you.

Right now our sunrise is near 7 AM. On a clear and calm night, the coldest time is about an hour before to a half-hour after sunrise.
