Incorrect, you do NOT use these methods outlined for plant cultivation for mushroom cultivation. Air inflated insulation types are NOT for Mushroom cultivation.
I will be using 1 layer of plastic a layer of 6 inch insulation R30-R32 and then another layer of plastic just how the professional mushroom tunnels are built.

Well can you tell me the reasoning behind this type of design? Does it have to do with cleaning/maintenance and pests etc? I am wondering how the benefits of this design, using 100% artificial heating in the winter, would outweigh the benefits of using the sun to heat it. Is taking advantage of solar heating totally out of the question? (not debating here, i just want a better understanding)

First thing, light control, I will not be only cultivating Oyster mushrooms, and I want to be able to control how much light my mushrooms get.
Second thing is the air insulation method used for plants is far less efficient than R30 insulation.
Again, the method you have described is used for Growing plants, not mushrooms.
I have been doing research on mushroom tunnels for years, dual layer plastic and using insulation is how its done.

I see the difference in fixed R value, plus I can see the ease in maintenance in a fixed double wall set up with insulation.
Light control could be adjusted by material type/opaqueness in either case.
Having lived in Fairbanks Alaska for 9 years, I have also seen the benefits of double walled plastic with an air pocket. Nobody has a cabin that is finished there (lol), but they live in them anyways, usually missing the expensive things.. like windows.. they staple gun up a piece of plastic on the inside of the frame and the outside, tyvek tape the edges. At 40 below the inside piece is warm to the touch (with a heater inside, no sun in the winter there). So, I do understand his idea does have benefits and insulates well.
But given the choice, I vote standard insulation as well.

The main problem with that type of setup that I see, is too much heat, and a shade cloth wouldn't cut it. I need temperatures of no more than 70F in my grow room but they can be as low as 50F. Too much light would inhibit mushroom growth as well.
Now if I opened up the grow room during the summer, and added a shade cloth, then the temperatures would still be to high, and I would have pest problems without screens (added cost). Also humidity would be greatly reduced.
My setup will utilize a hydronic heating system with a heat exchanger and an instant water heater, or regular water heater which is very efficient. I will also use a water chiller or a small air conditioner for cooling, and nightly air exchange for cooling(free).
If I used clear plastic and no insulation I could not use nightly air exchanges to bring night cool air and keep the the room cool for any amount of time.
You need to realize that mushrooms are grown differently than plants.
Plants require full sun and more heat and less humidity than that of mushrooms.

Nice.
Now that I see the terrain outside, I see why you didn't go with underground. Are you going to leave the concrete exposed or lay gravel over it? On mine, I poured a 5 1/2" curb around the edges, which will allow the grow room floor to hold that much gravel. By spraying with a hose, it should maintain humidity pretty well, or at least that's the plan. Keep the pics coming.
Where are you going to colonize the substrates?

What about using a metal roof and spraying foam insulation on? Or maybe Reflectix. The plastic will be cheaper but how long before you have to replace it? These are questions I am asking myself right now even as today we are laying the forms for a 12/50 ft. tunnel with six foot side walls. Here is the picture that inspired me for my design.

That link didn't work out too well. I was looking at the structure with the metal roof 10/ 30 ft.

spray foam is great stuff.. does not breathe at all. You might end up with an exhaust fan to control humidity. I lived in a spray foamed dome house and a dehumidifer running 24/7 left us with enough water to do all the dishes, do personal hygene, water the houseplants, and still get dumped constantly every 24 hrs. However, its very long lasting and again, a great insulator. Just have to plan for the massive condensation.

Would you have to put some bleach or peroxide in the rock water to prevent mold?
I would suggest using lava rocks. I used them in my PMP and they worked real well.

Lava rocks came to my mind as well. I am going to start off with two 4 teir greenhouses, with a drip pan. I wanted to avoid the perlite mess in the pans, but wanted something there to hold the moisture so it gets wicked back up. Lava rocks was on the list, good to hear they worked for you.
I would assume some regular interval cleaning would be neccessary in both small and large greenhouses though. At least in my set up there will be a simple drain plug. I think RR will have natural drainage due to the slope of the "cave" (conex).. please correct me. I also beleive I saw this slap had drainage in this set up, again correct me if I'm wrong. But in either case it should reduce risks to be able to drain out pools. Some bleaching on a schedule should be on the to do list, I imagine.

Correct. There won't be any standing water in mine. I have two 2" drain pipes leaving the fruiting area. I'll be using rocks I pick up in the mountains. Lava rock might have more surface area, but I'm going with what I can get up in the mountains locally for free, with only the work of shoveling it into my pickup truck.

I will not be using gravel on the bottom, which is why I spent the time in pouring a slab all the way across, I have a humidifan...

How much do your poles end up costing for a setup like this and what do you think of the hoop bender? Are you using one of their guides/plans for setup?
I was thinking the double poly air insulation was a good idea as well. This was the first time I'd heard it would have major downsides, but it makes sense.

No rocks around here  have to buy everything.. But, I think I choose lava rocks - nice and cheap, and effective.

in those links you posted, dave and dee's and open minded organics, the tunnels look almost exactly the same. does anybody know what company builds those tunnels, and how much they cost?

the pipe cost was $10 a pole, so it cost me around $250.00 for pipe, I just bent the pipes as instructed and built the building to my own plans.
Double poly air insulation is wrong. Use R30 unfaced fiberglass insulation.
To hot and too much light is the major problems.
It is good for cold climates, but poor for moderate to warm climates.
