Bundled my little ones up last night. Not exactly a green house, but it helps.
They were a bit warmer than air temp this morning.
Unfortunately my big girl was on her own. Quite a bit cooler in the yard.
Been giving them potassium silicate once a month or so to help protect from the cold. Will also add a little SuperThrive to their water this week to lessen any cold damage.
On the bright side supposed to have a high of 88 on Sunday.
