Winter high tunnel

My winter high tunnel is off a d running with tomatoes, green beans, and greens.  We will see how long it thrive.  I am trying to get the ends enclosed. The materials are on hand, but life keeps getting in the way.

Salad in high tunnel

looks real good. even if only it can extend end of season several weeks and help in late winter/early spring to get some things going and get a head start on spring/summer plantings.
what material did you use for the hoops?

Hi Bruce,

1.75 inch steel tubing.

The containers for the greens allow me to move them indoors for a couple of nights in case of a hard freeze of a couple of days.  I should be able to use the high tunnel, in this way, until  christmas.  I have wood heater for the high tunnel that I decided not to use this winter. I want to fully enclose it in a concrete block addition. I thought I has a green light on that project ... the weather proved me wrong.
