I have come across websites that state Grow Tubes could cause a plant
not to harden off enough to survive it's first Winter. Has anyone in
the Northern States used Grow tubes and had good survival rate for
their grapes first Winter? I have six new Grapes and six 29" long Snap
n Grow tubes that I'm itching to put around the new vines.
