Have you considered installing as much window-screen as you can, and comparing winter survival from the different protectants ?

I have to wonder if the apparently increased tenderness of the whips in the grow-tubes might actually be happening in the early spring, as the increasingly strong sunlight heats up the air in the tubes, but then the nights are still quite cold.

A generous nafexer donated a couple hundred grow tubes to our tree growing efforts here. Actually they are recycled tubes from some industrial application, heavy wall, translucent plastic 5" x 2'.
I have been told it is not a good idea to leave them on even year old whips through the dormanting season, because they will not harden off as well as if they had been fully exposed to the oncoming winter.
Snow and low 20'sF is the forcast here this week.
However, I have such a vole chewing problem that I am tempted to leave them on. I eventually depend on window screen for vole protection, but doubt I can get a couple hundred screen tubes in place by freeze-up this fall.
I'd like some opinions from folk out there on the subject of grow tubes and achieving full dormancy, or other winter concerns, thanks!, Del
