Ara and I just installed a new piece of greenhouse film on our nursery tunnel. The old film blew off in a storm last winter.

When we moved to our property, it was this tunnel’s third time to be constructed. It was originally built when were at our first rented plot. It had solid wood bottom boards and hip boards, roll up sides made with metal pipe and ropes to hold the sides from blowing in the wind.

We grew microgreens on a shelf hanging from the ridge pole.

Then we had to disassemble and rebuild it at our second rented plot. It went back together mostly the same, though it was tricky to get some things to line up and I had to drill some new holes in spots for the boards.

Then we moved to our current place, and almost nothing lined up after I rebuilt the metal frame. There are holes in the hoops and posts for the boards to bolt on and instead of drilling another set of new holes to make it line up, I left them off.

I also used some old farm gates from the horse paddocks that were here as my greenhouse benches, they work great!

It was always a bit loose after the third build since I didn’t have the side boards on the hoops. Over winter, a storm ripped the plastic off. I chose to rebuild it a simpler way this time, utilizing some techniques from our caterpillar tunnels.

The result is fully functional, much simpler, uses less materials and can also be opened up more for ventilation. And it was expedient, only taking a few hours to get it restored!

Instead of using solid hip and base boards, I used shorter J bolts in the holes of the ground posts and leftover rope from our other tunnels. The two runs of rope are thrown over the tunnel back and forth and hooked into the J bolts.

The rope prevents the plastic from billowing in the wind.

It still has the original channel lock on the end bows to hold the plastic. I used a few side curtain hooks on bows 3 & 5 for holding up the plastic for ventilation.

We got it covered again just in time for all the rain.

This is where we grow microgreens and transplants for our CSA, it’s solar powered!
