I worked for a car painter for a bit. He said paint will adhere to most rough surfaces so it should work although flexing plastic might be a problem.
We do have some 50-gallon barrels. I think they'd take up too much room in a small greenhouse like that, which is why I thought of a row of smaller buckets all along the planters.
I was thinking about that and had an idea. What if the barrels were mostly outside the greenhouse but using convection they could feed warmed water (thru convection?) to the one or two barrels within the greenhouse. Consider those inside being laid sideways under your growing tables. Your seals need to be first rate but that shouldn't be difficult.
The only Montana I've seen was a few hundred miles of highway but it was clearly dry high desert so your supply of sunlight should be great. It's mild here in Oregon but while I'm very pro-solar I often wonder if there's every a way to regain the initial costs in my state. Entire months of rain are the norm here.
We also mulch well and keep our soil in good shape to reduce water needs
My neighbors laughed at me a lot the year before I tried my first garden. I'm no farmer and went to the books to learn how to prepare the soil.
First I dug out the top 18 ins, to 2 ft. of my 14 x 6 ft. garden. I added an inch or two of sand for drainage too. Then all that summer I filled my van with my neighbors grass clippings. Marvelous things happen just sitting in hot garbage bags for a few weeks.
By Fall I had a fairly impressive mountain of rotting grass all ready for it's winter work. I now covered the crass with the two feet of earth removed earlier and dumped a big bag of lime on top.
That winter was very cold but also had heavy snows. Mt. Grassclippings grew so warm no snow would lay atop it. By early Spring it was steaming night & day.
The first crop of tomatoes required two extensions of poles until they reached 14 feet and bore obscenely large red fruit. No one laughed again and I was teaching Soil Prep 101 the rest of that year.
Is a well impractical? A reliance on rainwater is fine now but what if Mount St. Helens carpets you with a few inches of ash? I'm a big believer in having a solid Plan B for critical commodities and at 6.5 lbs. per gallon water is darn heavy to move around in quantity.
I used to keep a 100 gallon plastic vat in my mother's kitchen. (she was not amused). It used gravity to feed age, pre-aerated water to the tanks holding 3000 fish in the basement. Chemical companies and large medical supply houses too them out but it's best to know what they had once contained. Rural fire departments often can be extremely helpful filling things.
If the bulk of thermal mass in one container would work better than the collection of smaller buckets I could probably put one or maybe two of the barrels in there instead.
We collect rainwater off our house and sheds, and the excess is stored in stock tanks and 50-gallon plastic barrels in the garden. We don't have a well, so whatever water we use on the garden is either rainwater ('fresh' or stored) or has to be hauled from town. This time of year we fill everything we can so we have water in July and August for the garden.
