My greenhouse build

[Frank Surber]

I don't remember posting a thread about my greenhouse so I will start one'
I started building myself a greenhouse several years ago and never got around to completing it, Now that it is basically closed in and near enough to completion I'll post a few pictures of it

Very nice. I have had a small one(8x12) for a few yrs and really enjoy it. Ken Sweet

I like the water totes up high for irrigation and thermal mass. Are sides galvanized corrogated steel, or are those translucent fiberglass/acrylic panels?

 

[Frank Surber]

The walls are galvanized corrugated steel, the greenhouse is 32 by 16 with 10ft high walls 2 feet of that is buried in the ground with steel panels on both sides 3 layers of 15lb roofing tar paper over the part in the ground the cavities between the panels in the ground are sprayed with a wax coating and filled with dry sand. the peak of the roof has a utility pole running the length with a utility pole near the center for support the apex of the roof is 12 feet high off centered to the north of the structure making the north portion of the roof 6 feet in length at aprox 12/12 pitch the south roof is aprox 14 feet in length. currently it is roofed and the west wall with a single sheet of 6 mil plastic which eventually will need replacing. Before next summer I will have to add screen shading to cut down on the full effects of the sunlight and heat on a 60°f day the temp. inside can reach 130° and, on a 90°+ day I have noticed temps of over 155°f even with the doors open on both ends.
The totes have a combined total of 575 gallons of water and are painted black these will eventually have automatic refill via a float valve and will be plumbed to make a gravity irrigation system. Now that the totes are in place they do help to even out the temp swing by absorbing excess heat reducing the high temp and maintaining a higher low temp.
I have 4" closed cell PIR cardboard clad freezer insulation panels to line the North wall with and enough room against the upper portion of the North wall

What are the arches made from? Is there a softening cushion between the plastic and the arches?

The arches are made from 2" black poly pipe
