As of this morning:
Small greenhouse build

Minus finishing touches such as paint, trim, caulking, and the garden it's done. The rain barrel needs hooked up and benches will be built on the side. It's far from perfect but I'm pretty happy with myself considering I've not built anything like this before.

Looks great. Are you doing passive or active cooling or heating?

Passive. I don't want to use electric but if it doesn't work out I'll look into a small solar panel.

Ok, well keep me posted I'm interested to see how it works for you.

I will!

Took advantage of the box store plant sales and did the garden.

Nice. Better get the caulk out and seal that corner seam...

Caulk and trim.

Awesome build! I’ll be interested to see what min temps you can keep. I can understand not wanting to use electricity. Depending on your species, it seems like many growers use heat mats to keep the roots above a ‘danger’ temp. So my envelope math for a 5ft long 150W mat on for 24hrs/day @ $0.12 kWh is $13/month. It also doesn’t seem like it would have to be on that long and it might be the only heat you need if your passive heat works as expected.

Pretty cool build. I noticed that you mixed lumber building this. Did you used treated fasteners? The siding may not hold in a bad storm if the ACQ has eaten up your fasteners. Something to consider so you don't loose your trees if it collapses.

Any wood touching or close to the ground is treated. Most of the frame is treated wood.

I was actually referring to your studs and top plate, they look like they are standard kiln dried lumber. Attaching that to PT wood without using ACQ rated fasteners WILL eventually result in structure failure. ACQ will eat up steel and even zinc plated screws fairly quickly. Even the PT wood you used on the ground should be rated for ground contact as they will "last" longer. I do applaud you for your efforts though, but these are some things to keep in mind. You really don't want to be under something that can fall on top of you.

The PT wood is rated for ground contact. You are correct about the studs and top though, they aren't treated. I'm not sure if the screws are ACQ rated. I just used outdoor wood screws. So are you saying what the wood is treated with will break down metals? Is that what ACQ is? My dad did help with picking out the materials so hopefully the fasteners are okay to have used.

Hot dipped galvanized, stainless steel, painted screws would work, but they cost a bit more. You would have to ask your dad or read the packaging of the fasteners. If you still have access to the studs on the inside then just follow up with ACQ treated fasteners while leaving the original fasteners you used to tie everything together. Be careful when toenailing as you can split the ends. Better to be safe than sorry.

Thanks! Most of the screws looked like they were painted brown. I'll check one of the packages to make sure.

If they were star drive and painted tan they were most likely deck screws.

It looks like according to the package they are stainless steel and galvanized with rustoleum paint.

They are star drive. Thanks for all the info! It'll be useful for the benches and shelves I still need to do.

If you hook the mats up to thermostats that have probes, then the mats are only on part of the time, to raise the root temps to your desired level. I keep mine at about 35 or so.
