Once you have your high tunnel up you will have a real advantage in doing winter vegetable plantings. (Remember however there is less sun per day so you can no longer rely on the stated "Matures In" dates on seed packages! )
I did four of each variety of Bok Choy just to try them all. Next year is when I’ll really grow some and had planned to do succession plantings in the tunnel. I’ll have to check day length charts and average temperature charts.
There’s a reason I only planted four of each. I know not what I’m doing with Bok Choy. Bok Choy is a weird one in that a cold snap or nights below 50 may make it bolt. (just learned that this morning) Kind of opposite to most stuff we grow.
Each layer of plastic also reduces light intensity which is already low in Winter.
Picked up white paint for the tunnel frames this morning. I’m forgoing the primer. The rust treatment I use describes itself as a primer and ready to paint the next day, plus the paint I got is a rust preventative, direct to metal type.
Time to go weld up the four remaining frames and spray them all with Ospho.
