18 overnight again. But the ice is nature’s R/O: water freezes leaving sweeter sap: from 2.5 Brix to 3.0 Brix.
Collected 70 gallons. Done by 5:00 PM.
Took until after Noon to warm to high 30s and even later for 40. By 5:30 it was below 32 already. The ground is still cold.
Put out the tree pressure gauge. 18 PSI today.
