Ground temp here is 55 F. Hoping to heat up the clay in the ground, as I don't want the water temp to fluctuate too much. And yes my arms and shoulders are still aching from all that digging. Slowly filling the FT up with well water, and some rain water today too.
shovel got some use too, as I started working on the wall near the FT, I had to move the dirt and clay to make room for the ladder.
No new pictures today, but I did find a used exterior door for $10, so hopefully tomorrow I can finish the first wall and maybe even put some plastic up soon.

Considering stretch wrapping the outside PVC poles to the wood frame that I built, then applying that expanding foam inside the stretch wrap. Should stiffen up the wall considerably sticking to both the PVC and the wood frame.

Still not comfortable with supporting the PVC. I think I might run some 2x4 from the center beam to hold up some coduit to hold up the PVC.
