Learned something today. We have a commercial double sized fridge in our kitchen. Got it about 3 years ago and last week on Thanksgiving day it stopped reaching setpoint.

I never heard of R290 refrigerant and could not find any HVAC guys to work on it. I assumed it had a slow leak. Called a commercial fridge place and they said they might get to me by this Friday. On a lark I called another commercial fridge place and the guy said he was out in my area anyway and he stopped by 45 minutes later. He installed a service port on the plumbing and refilled it and it works. He couldn't find a leak so it might have been in the crimped over stub of tubing he cut off to install the service port.

Now on to the good stuff. R290 is simply a very pure propane. That's it. Friggin propane. It's not a controlled substance like other refrigerants. You can buy three 8oz cans of it on amazon with a fill kit for $60. My fridge holds 3.6oz of it...

Turns out that propane is a very good refrigerant but R12 replaced it because it was flammable. But improvements in compressors mean it is not a fire hazard so it's making a comeback. Goodwe and Gee are making minisplit systems that use it. Apparently it's all the rage in EU and China.

All based on jewusury.

Doucan inventory as of Dec 4 2025.

Today, under threat of rain, we got the last verticals for the end walls concreted in and plumb. Supposed to rain tomorrow. But the green house is now to the point that one person can complete most remaining tasks. I'll have to frame out the end walls. We opted for steel end walls and corrugated poly carb panels. They offer wood endwalls, but I think that's a false economy. They supply the brackets and I gotta source the 2x4's locally. Given the price of lumber and the idea that I'd have to take it apart and redo in the future wasn't worth it to me. Buy once and Cry once.

Once the end walls are framed out, I'll have to dig a 6" deep trench across the end for the poly carb panels to sit in... then we wil back fill with dirt as a rodent barrier.

How to calculate cubic yards of concrete for a job. Length (ft) x Width (ft) x depth (inches) / 300.

40ft x 40ft x 4in = 6400/300 = 21 1/3 yards.

A concrete truck holds 10 yards.

Working on the green house, having a man basket is a life saver. It allows me access up high without leaning a ladder on the frame and making things not plumb. Wife is lifting me up and down and she's doing a fantastic job keeping me level as she lifts.
